Cannabis Myths vs Reality
We asked you for your (health-related) opinion on cannabis use—specifically, the kind with psychoactive THC, not just CBD. We got the above-pictured, below-described, spread of responses:
- A little over a third of you voted for “It’s a great way to relax, without most of the dangers of alcohol”.
- A little under a third of you voted for “It may have some medical uses, but recreational use is best avoided”.
- About a quarter of you voted for “The negative health effects outweigh the possible benefits”
- Three of you voted for “It is the gateway to a life of drug-induced stupor and potentially worse”
So, what does the science say?
A quick legal note first: we’re a health science publication, and are writing from that perspective. We do not know your location, much less your local laws and regulations, and so cannot comment on such. Please check your own local laws and regulations in that regard.
Cannabis use can cause serious health problems: True or False?
True. Whether the risks outweigh the benefits is a personal and subjective matter (for example, a person using it to mitigate the pain of late stage cancer is probably unconcerned with many other potential risks), but what’s objectively true is that it can cause serious health problems.
One subscriber who voted for “The negative health effects outweigh the possible benefits” wrote:
❝At a bare minimum, you are ingesting SMOKE into your lungs!! Everyone SEEMS TO BE against smoking cigarettes, but cannabis smoking is OK?? Lung cancer comes in many forms.❞
Of course, that is assuming smoking cannabis, and not consuming it as an edible. But, what does the science say on smoking it, and lung cancer?
There’s a lot less research about this when it comes to cannabis, compared to tobacco. But, there is some:
❝Results from our pooled analyses provide little evidence for an increased risk of lung cancer among habitual or long-term cannabis smokers, although the possibility of potential adverse effect for heavy consumption cannot be excluded.❞
Read: Cannabis smoking and lung cancer risk: Pooled analysis in the International Lung Cancer Consortium
Another study agreed there appears to be no association with lung cancer, but that there are other lung diseases to consider, such as bronchitis and COPD:
❝Smoking cannabis is associated with symptoms of chronic bronchitis, and there may be a modest association with the development of chronic obstructive pulmonary disease. Current evidence does not suggest an association with lung cancer.❞
Read: Cannabis Use, Lung Cancer, and Related Issues
Cannabis edibles are much safer than smoking cannabis: True or False?
Broadly True, with an important caveat.
One subscriber who selected “It may have some medical uses, but recreational use is best avoided”, wrote:
❝I’ve been taking cannabis gummies for fibromyalgia. I don’t know if they’re helping but they’re not doing any harm. You cannot overdose you don’t become addicted.❞
Firstly, of course consuming edibles (rather than inhaling cannabis) eliminates the smoke-related risk factors we discussed above. However, other risks remain, including the much greater ease of accidentally overdosing.
❝Visits attributable to inhaled cannabis are more frequent than those attributable to edible cannabis, although the latter is associated with more acute psychiatric visits and more ED visits than expected.❞
Note: that “more frequent” for inhaled cannabis, is because more people inhale it than eat it. If we adjust the numbers to control for how much less often people eat it, suddenly we see that the numbers of hospital admissions are disproportionately high for edibles, compared to inhaled cannabis.
Or, as the study author put it:
❝There are more adverse drug events associated on a milligram per milligram basis of THC when it comes in form of edibles versus an inhaled cannabis. If 1,000 people smoked pot and 1,000 people at the same dose in an edible, then more people would have more adverse drug events from edible cannabis.❞
See the numbers: Acute Illness Associated With Cannabis Use, by Route of Exposure
Why does this happen?
- It’s often because edibles take longer to take effect, so someone thinks “this isn’t very strong” and has more.
- It’s also sometimes because someone errantly eats someone else’s edibles, not realising what they are.
- It’s sometimes a combination of the above problems: a person who is now high, may simply forget and/or make a bad decision when it comes to eating more.
On the other hand, that doesn’t mean inhaling it is necessarily safer. As well as the pulmonary issues we discussed previously, inhaling cannabis has a higher risk of cannabinoid hyperemesis syndrome (and the resultant cyclic vomiting that’s difficult to treat).
You can read about this fascinating condition that’s sometimes informally called “scromiting”, a portmanteau of screaming and vomiting:
Cannabinoid Hyperemesis Syndrome
You can’t get addicted to cannabis: True or False?
False. However, it is fair to say that the likelihood of developing a substance abuse disorder is lower than for alcohol, and much lower than for nicotine.
See: Prevalence of Marijuana Use Disorders in the United States Between 2001–2002 and 2012–2013
If you prefer just the stats without the science, here’s the CDC’s rendering of that:
Addiction (Marijuana or Cannabis Use Disorder)
However, there is an interesting complicating factor, which is age. One is 4–7 times more likely to develop a substance abuse disorder, if one starts use as an adolescent, rather than later in life:
Cannabis is the gateway to use of more dangerous drugs: True or False?
False, generally speaking. Of course, for any population there will be some outliers, but there appears to be no meaningful causal relation between cannabis use and other substance use:
Interestingly, the strongest association (where any existed at all) was between cannabis use and opioid use. However, rather than this being a matter of cannabis use being a gateway to opioid use, it seems more likely that this is a matter of people looking to both for the same purpose: pain relief.
As a result, growing accessibility of cannabis may actually reduce opioid problems:
- Cannabis as a Gateway Drug for Opioid Use Disorder
- Association between medical cannabis laws and opioid overdose mortality has reversed over time
Some final words…
Cannabis is a complex drug with complex mechanisms and complex health considerations, and research is mostly quite young, due to its historic illegality seriously cramping science by reducing sample sizes to negligible. Simply put, there’s a lot we still don’t know.
Also, we covered some important topics today, but there were others we didn’t have time to cover, such as the other potential psychological benefits—and risks. Likely we’ll revisit those another day.
Lastly, while we’ve covered a bunch of risks today, those of you who said it has fewer and lesser risks than alcohol are quite right—the only reason we couldn’t focus on that more, is because to talk about all the risks of alcohol would make this feature many times longer!
Meanwhile, whether you partake or not, stay safe and stay well.

Avoiding Anemia (More Than Just “Get More Iron”)
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
The Iron Dilemma: Factors To Consider
Anemia affects around 10% of American seniors, and that number jumps to 34–39% if there’s a comorbidity such as diabetes, hypertension, or hypercholesterolemia, which in turn climbs with increasing age or with other chronic conditions:
So, what can we do about it?
Get iron yes, but how?
We’d be remiss not to say: yes, do of course make sure you get plenty of iron.
Most people know that red meats, which are terrible for the heart and for cancer risk, are good sources of iron.
Well, good insofar as they provide plenty of it! They’re bad for other reasons.
❝Studies consistently show that consumption of red meat has been contributory to a multitude of chronic conditions such as diabetes, CVD, and malignancies.
There are various emerging reasons that strengthen this link-from the basic constituents of red meat like the heme iron component, the metabolic reactions that take place after consumption, and finally to the methods used to cook it.
The causative links show that even occasional use raises the risk of T2DM.❞
Source: Red Meat Consumption (Heme Iron Intake) and Risk for Diabetes and Comorbidities?
To heme or not to heme
Did you catch that in the middle there, about the heme iron component?
Dietary iron is broadly divided into two kinds: heme, and non-heme.
- Heme iron comes from animals
- Non-heme iron comes from plants
Bad news for vegans: non-heme iron is not so easily absorbed as heme iron.
This means that if you’re just eating plants, the RDA may be significantly lowballing the amount actually required. As a rule, about 1.8x more iron may be needed for vegans, to compensate for it being less easily absorbed.
Why this happens: it’s because of the phytic acid / phytate in the plants that contain the iron, blocking its absorption.
Good news for vegans: however, taking iron with vitamin C increases its absorption rate by about 5x better absorption, and several other side-along nutrients do similarly, including allium (from garlic), carotenoids (from many colorful plants), and fermented foods.
Why this happens: it’s because they bind with similar sites as phytic acid, without causing the same effect. To make a metaphor: these foods steal phytic acid’s parking space, so phytic acid can’t do its iron-blocking thing.
By happy coincidence, today’s featured recipe has all of these things in, by the way (vitamin C, allium, carotenoids, and fermented foods), and the star ingredient (fava beans) is a rich source of iron.
What are good sources of iron, then?
In the category of plants:
- Beans (pick your favorites / eat a variety)
- Lentils (pick your favorites / eat a variety)
- Greens (especially dark leafy greens)
- Apricots (you can get these dried, for convenience!)
- Dark chocolate (5mg per 1oz square!)*
*Ok, technically dark chocolate is not a plant; cacao is a plant; dark chocolate is usually plant-based, though, as there is no reason to add milk.
In the category of dairy products:
That’s not a publication error; dairy products are just not great for iron. Cheeses are more nutrient-dense than milk, and have less than 0.5mg per oz, in other words, the top dairy product has around 10x less iron than dark chocolate, which came in 5th place and let’s face it, we were doing broad categories there. If we listed all the beans, lentils, greens, etc it’d be a much longer list.
Eggs, which are sometimes considered under the category of dairy by virtue of not being an animal (yet!) but an animal product, have around 1mg per egg, by the way, so considering eggs are nearer 2oz, that’s not much better than the cheese.
“But what about if…”
The above is good science and general good advice for most people. That said, some people may have conditions that preclude the foods we recommended, or have other considerations, and so things may be different. Anemia can sometimes be caused by things that can’t be fixed by diet (beyond the scope of today’s article; another time, perhaps), but for example, if you have leukemia then definitely discuss things with your doctors first. Other illnesses, and some medications, can also have troublesome effects that can contribute to anemia. Again, we can offer very good general information here, but we don’t know your medical history, and our standard legal/medical disclaimer applies as always.

Longevity for the Lazy – by Dr. Richard Malish
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
There are some people who devote all their resources to longevity, which can become a full-time occupation, not to mention a very expensive endeavor. This book’s for those who want to get the best possible “bang for buck” by doing the things that have the most favorable cost:worth ratio.
Dr. Malish covers what can be done easily for personal longevity, as well as what technological advances can be enjoyed that those before us didn’t have as options. He also discusses the diseases that are most likely to kill us, and how to avoid those.
He preaches a proactive approach, but one that is simple and consistent and based in good science, and good statistics. Indeed, while he’s served 20 years as an army doctor and a cardiologist, he now works as a healthcare policy consultant, so he is well-placed to advise.
The style of the book is halfway between regular pop-science and a textbook; you can either read it cover-to-cover, or skim first though the key points, highlight boxes, summaries, and the like. He also provides a time-phased task list, for those who like things to be laid out like that.
Bottom line: this is a very good, methodical guide to living longer without making it a full-time occupation.

The Orchid That Renovates Your Gut (Gently)

The Orchid That Renovates Your Gut (Gently)
Dendrobium officinale is an orchid that’s made its way from Traditional Chinese Medicine into modern science.
Read: Traditional Uses, Phytochemistry, Pharmacology, and Quality Control of Dendrobium officinale
To summarize its benefits, we’ll quote from Dr. Paharia’s article featured in our “what’s happening in the health world” section all so recently:
❝Gut microbes process Dendriobium officinale polysaccharides (DOPs) in the colon, producing short-chain fatty acids (SCFAs) and oligosaccharides that alter gut microbial composition and improve human health.
DOPs have been shown to decrease harmful bacteria like E. coli and Staphylococcus while promoting beneficial ones like Bifidobacterium.❞
We don’t stop at secondary sources, though, so we took a look at the science.
Dr. Wu et al. found (we’ll quote directly for these bullet points):
- DOPs have been shown to influence the gut microbiota, such as the abundance of Lactobacillus, Bifidobacterium, Akkermansia, Bacteroides, and Prevotella, and provide different benefits to the host due to structural differences.
- The dietary intake of DOPs has been shown to improve the composition of the gut microbiome and offers new intervention strategies for metabolic diseases such as obesity and type 2 diabetes as well as inflammatory diseases such as chronic obstructive pulmonary disease and colitis.
- Compared to drug therapy, intervention with DOPs is not specific and has a longer intervention duration
This is consistent with previous research on Dendrobium officinale, such as last year’s:
❝DOP significantly increased benign intestinal microbe proportion (Lactobacillus, etc.), but reduced harmful bacteria (Escherichia shigella) (P < 0.05), and significantly increased butyric acid production (P < 0.05)❞
In summary…
Research so far indicates that this does a lot of good for the gut, in a way that can “kickstart” healthier, self-regulating gut microbiota.
As to its further prospects, check out:
Very promising!

An Underrated Tool Against Alzheimer’s
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Dementia in general, and Alzheimer’s in particular, affects a lot of people, and probably even more than the stats show, because some (estimated to be: about half) will go undiagnosed and thus unreported:
Alzheimer’s: The Bad News And The Good
At 10almonds, we often talk about brain health, whether from a nutrition standpoint or other lifestyle factors. For nutrition, by the way, check out:
Today we’ll be looking at some new science for an underrated tool:
Bilingualism as protective factor
It’s well-known that bilingualism offers brain benefits, but most people would be hard-pressed to name what, specifically, those brain benefits are.
As doctors Kristina Coulter and Natalie Phillips found in a recent study, one of the measurable benefits may be a defense against generalized (i.e. not necessarily language-related) memory loss Alzheimer’s disease.
Specifically,
❝We used surface-based morphometry methods to measure cortical thickness and volume of language-related and AD-related brain regions. We did not observe evidence of brain reserve in language-related regions.
However, reduced hippocampal volume was observed for monolingual, but not bilingual, older adults with AD. Thus, bilingualism is hypothesized to contribute to reserve in the form of brain maintenance in the context of AD.❞
Read in full: Bilinguals show evidence of brain maintenance in Alzheimer’s disease
This is important, because while language is processed in various parts of the brain beyond the scope of this article, the hippocampi* are where memory is stored.
*usually mentioned in the singular as “hippocampus”, but you have one on each side, unless some terrible accident or incident befell you.
What this means in practical terms: these results suggest that being bilingual means we will retain more of our capacity for memory, even if we get Alzheimer’s disease, than people who are monolingual.
Furthermore, while we’re talking practicality:
❝…our subsample may be characterized as mostly late bilinguals (i.e., learning an L2 after age 5), having moderate self-reported L2 ability, and relatively few participants reporting daily L2 use (33 out of 119)❞
(L2 = second language)
This is important, because it means you don’t have to have grown up speaking multiple languages, you don’t even have to speak it well, and you don’t have to be using your second language(s) on a daily basis, to enjoy benefits. Merely having them in your head appears to be sufficient to trigger the brain to go “oh, we need to boost and maintain the hippocampal volume”.
We would hypothesize that using second language(s) regularly and/or speaking second language(s) well offers additional protection, and the data would support this if it weren’t for the fact that the sample sizes for daily and high-level speakers are a bit small to draw conclusions.
But the important part is: simply knowing another language, including if you literally just learned it later in life, is already protective of hippocampal volume in the context of Alzheimer’s disease.
Here’s a pop-science article about the study, that goes into it in more detail than we have room to here:
Bilingualism linked to greater brain resilience in older adults
Want to learn a new language?
Here are some options where you can get going right away:
If you are thinking “sounds good, but learning a language is too much work”, then that is why we included that third option there. It’s specifically for one language, and that language is Esperanto, arguably the world’s easiest language and specifically designed to be super quick and easy to get good at. Also, it’s free!

Can You Get Addicted To MSG, Like With Sugar?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small 😎
❝Hello, I love your newsletter 🙂 Can I have a question? While browsing through your recepies, I realised many contained MSG. As someone based in Europe, I am not used to using MSG while cooking (of course I know that processed food bought in supermarket containes MSG). There is a stigma, that MSG is not particulary healthy, but rather it should be really bad and cause negative effects like headaches. Is this true? Also, can you get addicted to MSG, just like you get addicted to sugar? Thank you :)❞
Thank you for the kind words, and the interesting questions!
Short answer: no and no 🙂
Longer answer: most of the negative reputation about MSG comes from a single piece of satire written in the US in the 1960s, which the popular press then misrepresented as a genuine concern, and the public then ran with, mostly due to racism/xenophobia/sinophobia specifically, given the US’s historically not fabulous relations with China, and the moniker of “Chinese restaurant syndrome”, notwithstanding that MSG was first isolated in Japan, not China, more than 100 years ago.
The silver lining that comes out of this is that because of the above, MSG has been one of the most-studied food additives in recent decades, with many teams of scientists in many countries trying to determine its risks and not finding any (except insofar as anything in extreme quantities can kill you, including water or oxygen).
You can read more about this and other* myths about MSG, here:
Monosodium Glutamate: Sinless Flavor-Enhancer Or Terrible Health Risk?
*such as pertaining to gluten sensitivity, which in reality MSG has no bearing on whatsoever as it does not contain gluten and is not even made of the same basic stuff; gluten being a protein made of (amongst other things) the amino acid glutamine, not a glutamate salt. Glutamate is as closely related to gluten as cyanocobalamin (vitamin B12) is to cyanide (the famous poison).
PS: if you didn’t click the above link to read that article, then 1) we really do recommend it 2) we did some LD50 calculations there and looked at available research, and found that for someone of this writer’s (very medium) size, eating 1kg of MSG at once is sufficient to cause toxicity, and injecting >250g of MSG may cause heart problems. So we don’t recommend doing that.
However, ½ tsp in a recipe that gives multiple portions is not going to get you anywhere close to the danger zone, unless you consume that entire meal by yourself hundreds of times per day. And if you do, the MSG is probably the least of your concerns.
(2 tsp of cassia cinnamon, however, is enough to cause coumarin toxicity; for this reason we recommend Ceylon (or “True” or “Sweet”) cinnamon in our recipes, as it has almost undetectable levels of coumarin)
With regard to your interesting question about addiction, first of all let’s speak briefly about sugar addiction:
Sugar addiction is, by broad scientific consensus, agreed-upon as an extant thing that does exist, and contemporary research is more looking into the “hows” and “whys” and “whats” rather than the “whether”. It is a somewhat complicated topic, because it’s halfway between what science would usually consider a chemical addiction, and what science would usually consider a behavioral addiction:
The Not-So-Sweet Science Of Sugar Addiction
The reasonable prevailing hypothesis, therefore, is that sugar simply has two moderate mechanisms of addiction, rather than one strong one.
The biochemical side of sugar addiction comes from the body’s metabolism of sugar, so this cannot be a thing for MSG, because there is nothing to metabolize in the same sense of the word (MSG being an inorganic compound with zero calories).
People can crave salt, especially when deficient in it, and MSG does contain sodium (it’s what the “S” stands for), but it contains a little under ⅓ of the sodium that table salt does (sodium chloride in whatever form, be it sea salt, rock salt, or such):
MSG vs. Salt: Sodium Comparison ← we do molecular calculations here!
Sea Salt vs MSG – Which is Healthier? ← this one for a head-to-head
However, even craving salt does not constitute an addiction; nobody is shamefully hiding their rock salt crystals under their bed and getting a fix when they feel low, and nor does withdrawal cause adverse side effects, except insofar as (once again) a person deficient in salt will crave salt.
Finally, the only other way we know of that one might wonder if MSG could be addictive, is about glutamate and glutamate receptors. The glutamate in MSG is the same glutamate (down to the atoms) as the glutamate formed if one consumes tomatoes in the presence of salt, and triggers the same glutamate receptors in the same way. We have the same number of receptors either way, and uptake is exactly the same (because again, it’s exactly the same chemical) so there is a maximum to how strong this effect can be, and that maximum is the same whatever the source of the glutamate was.
In this respect, if MSG is addictive, then so is a tomato salad with a pinch of salt: it’s not—it’s just tasty.
We haven’t cited papers in today’s article, but it’s just because we cited them already in the articles we linked, and so we avoided doubling up. Most of them are in that first link we gave 🙂
One final note
Technically anyone can develop a sensitivity to anything, so in theory someone could develop a sensitivity to MSG, just like they could for any other ingredient. Our usual legal/medical disclaimer applies.
However, it’s certainly not a common trigger, putting it well below common allergens like nuts (or less common allergens like, say, bananas), not even in the same league as common intolerances such as gluten, and less worthy of health risk warnings than, say, spinach (high in oxalates; fine for most people but best avoided if you have kidney problems).
The reason we use it in the recipes we use it in, is simply because it’s a lower-sodium alternative to salt, and while it contains a (very) tiny bit less sodium than low-sodium salt (which itself has about ⅓ the sodium of regular salt), it has more of a flavor-enhancing effect, such that one can use half as much, for a more than sixfold total sodium reduction. Which for most of us in the industrialized world, is beneficial.
Want to try some?
