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:

See: Likelihood of developing an alcohol and cannabis use disorder during youth: Association with recent use and age

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:

Is marijuana really a gateway drug? A nationally representative test of the marijuana gateway hypothesis using a propensity score matching design

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:

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.

  • The Seven Principles for Making Marriage Work – by Dr. John Gottman

    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.

    A lot of relationship advice can seem a little wishy-washy. Hardline clinical work, on the other hand, can seem removed from the complex reality of married life. Dr. Gottman, meanwhile, strikes a perfect balance.

    He looks at huge datasets, and he listens to very many couples. He famously isolated four relational factors that predict divorce with 91% accuracy, his “Four Horsemen”:

    1. Criticism
    2. Contempt
    3. Defensiveness
    4. Stonewalling

    He also, as the title of this book promises (and we get a chapter-by-chapter deep-dive on each of them) looks at “Seven principles for making marriage work”. They’re not one-word items, so including them here would take up the rest of our space, and this is a book review not a book summary. However…

    Dr. Gottman’s seven principles are, much like his more famous “four horsemen”, deeply rooted in science, while also firmly grounded in the reality of individual couples. Essentially, by listening to very many couples talk about their relationships, and seeing how things panned out with each of them in the long-term, he was able to see what things kept on coming up each time in the couples that worked out. What did they do differently?

    And, that’s the real meat of the book. Science yes, but lots of real-world case studies and examples, from couples that worked and couples that didn’t.

    In so doing, he provides a roadmap for couples who are serious about making their marriage the best it can be.

    Bottom line: this is a must-have book for couples in general, no matter how good or bad the relationship.

    • For some it’ll be a matter of realising “You know what; this isn’t going to work”
    • For others, it’ll be a matter of “Ah, relief, this is how we can resolve that!”
    • For still yet others, it’ll be a matter of “We’re doing these things right; let’s keep them forefront in our minds and never get complacent!”
    • And for everyone who is in a relationship or thinking of getting into one, it’s a top-tier manual.

  • Tight Hamstrings? Here’s A Test To Know If It’s Actually Your Sciatic Nerve

    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.

    Tight hamstrings are often not actually due to hamstring issues, but rather, are often being limited by the sciatic nerve. This video offers a home test to determine if the sciatic nerve is causing mobility problems (and how to improve it, if so):

    The Connection

    Try this test:

    • Sit down with a slumped posture.
    • Extend one leg with the ankle flexed.
    • Note any stretching or pulling sensation behind the knee or in the calf.
    • Bring your head down to your chest

    If this increases the sensation, it likely indicates sciatic nerve involvement.

    If only the hamstrings are tight, head movement won’t change the stretch sensation.

    This is because the nervous system is a continuous structure, so head movement can affect nerve tension throughout the body. While this can cause problems, it can also be integral in the solution. Here are two ways:

    • Flossing method: sit with “poor” slumped posture, extend the knee, keep the ankle flexed, and lift the head to relieve nerve tension. This movement helps the sciatic nerve slide without stretching it.
    • Even easier method: lie on your back, grab behind the knee, and extend the leg while extending the neck. This position avoids compression in the gluteal area, making it suitable for severely compromised nerves. Perform the movement without significant stretching or pain.

    In both cases: move gently to avoid straining the nerve, which can worsen muscle tension. Do 10 repetitions per leg, multiple times a day; after a week, increase to 20 reps.

    A word of caution: speak with your doctor before trying these exercises if you have underlying neurological diseases, cut or infected nerves, or other severe conditions.

  • Body by Science – by Dr. Doug McGuff & John Little

    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 idea that you’ll get a re-sculpted body at 12 minutes per week is a bold claim, isn’t it? Medical Doctor Doug McGuff and bodybuilder John Little team up to lay out their case. So, how does it stand up to scrutiny?

    First, is it “backed by rigorous research” as claimed? Yes… with caveats.

    The book uses a large body of scientific literature as its foundation, and that weight of evidence does support this general approach:

    • Endurance cardio isn’t very good at burning fat
    • Muscle, even just having it without using it much, burns fat to maintain it
    • To that end, muscle can be viewed as a fat-burning asset
    • Muscle can be grown quickly with short bursts of intense exercise once per week

    Why once per week? The most relevant muscle fibers take about that long to recover, so doing it more often will undercut gains.

    So, what are the caveats?

    The authors argue for slow reps of maximally heavy resistance work sufficient to cause failure in about 90 seconds. However, most of the studies cited for the benefits of “brief intense exercise” are for High Intensity Interval Training (HIIT). HIIT involves “sprints” of exercise. It doesn’t have to be literally running, but for example maxing out on an exercise bike for 30 seconds, slowing for 60, maxing out for 30, etc. Or in the case of resistance work, explosive (fast!) concentric movements and slow eccentric movements, to work fast- and slow-twitch muscle fibers, respectively.

    What does this mean for the usefulness of the book?

    • Will it sculpt your body as described in the blurb? Yes, this will indeed grow your muscles with a minimal expenditure of time
    • Will it improve your body’s fat-burning metabolism? Yes, this will indeed turn your body into a fat-burning machine
    • Will it improve your “complete fitness”? No, if you want to be an all-rounder athlete, you will still need HIIT, as otherwise anything taxing your under-worked fast-twitch muscle fibers will exhaust you quickly.

    Bottom line: read this book if you want to build muscle efficiently, and make your body more efficient at burning fat. Best supplemented with at least some cardio, though!

    Morning Routines That Just FLOW

    “If the hardest thing you have to do in your day is eat a frog, eat that frog first!”, they say.

    And, broadly speaking, it is indeed good to get anything stressful out of the way early, so that we can relax afterwards. But…

    • Are we truly best at frog-eating when blurry-eyed and sleepy?
    • Is there a spoonful of sugar that could make the medicine go down better?
    • What do we need to turn eating the frog into an enjoyable activity?

    Flow

    “Flow” is a concept brought to public consciousness by psychologist Mihaly Csikszentmihalyi, and it refers to a state in which we feel good about what we’re doing, and just keep doing, at a peak performance level.

    Writer’s note: as a writer, for example…

    Sometimes I do not want to write, I pace to and fro near my computer, going on side-quests like getting a coffee or gazing out of the window into my garden. But once I get going, suddenly, something magical happens and before I know it, I have to trim my writing down because I’ve written too much. That magical window of effortless productivity was a state of flow.

    Good morning!

    What is a good morning, to you? Build that into your morning! Set parameters around it so you don’t get carried away timewise and find yourself in the afternoon (unless that would work for you!), but first thing in the morning is the time to light up each part of your brain with appropriate neurotransmitters.

    Getting the brain juices flowing

    Cortisol

    When we wake up, we (unless we have some neurochemical imbalance, such as untreated depression) get a spike of cortisol. Cortisol is much-maligned and feared, and indeed it can be very much deleterious to the health in cases of chronic stress. But a little spike now and again is actually beneficial for us.

    Quick Tip: if you want to artificially stimulate (or enhance) a morning cortisol spike, a cold shower is the way to go. Or even just a face-plunge into a bowl of ice-water (put ice in it, give it a couple of minutes to chill the water, then put your face in for a count of 30 seconds, or less if you can’t hold your breath that long).

    Serotonin

    Serotonin is generally thought of as “the happy chemical”, and it’s stimulated by blue/white light, and also by seeing greenery.

    Quick tip: to artificially stimulate (or enhance) a morning serotonin boost, your best friend is sunlight. Even sun through a partly-clouded sky will tend to outperform artificial lighting, including artificial sunlight lighting. Try to get sun between 08:30 and 09:00, if you can. Best of all, do it in your garden or nearby park, as the greenery will be an extra boost!

    Dopamine

    Generally thought of as “the reward chemical”, but it’s also critical for a lot of kinds of brainwork, including language processing and problem-solving.

    Quick Tip: to artificially stimulate* a dopamine surge to get you going, do something that you and/or your body finds rewarding. Examples include:

    • Exercise, especially in a vigorous burst
    • A good breakfast, a nice coffee, whatever feels right to you
    • An app that has motivational bells and whistles, a streak for you to complete, etc

    Note: another very enjoyable activity might come to mind that doesn’t even require you getting out of bed. Be aware, however, gentleman-readers specifically, that if you complete that activity, you’ll get a prolactin spike that will wipe out the dopamine you just worked up (because prolactin is antagonistic to dopamine). So that one’s probably better for a lazy morning when you can go back to sleep, than a day when you want to get up and go! Ladies, this is less of a worry for us as the physiology an orgasm driven by estrogen+progesterone rather than testosterone is different; there will not usually be a prolactin spike following the spike of dopamine; our orgasm-related dopamine spike is followed by a wave of oxytocin instead (“the cuddle chemical”), which is much more pleasant than prolactin.

    *there’s no “(or enhance)” for this one; you won’t get dopamine from doing nothing, that’s just not how “the reward chemical” works

    Flow-building in a stack

    When you’ve just woken up and are in a blurry morning haze, that’s not the time to be figuring out “what should I be doing next?”, so instead:

    • Work out the things you want to incorporate into your morning routine
    • Put them in the order that will be easiest to perform—some things will go a lot better after others!
    • Remember to also include things that are simply necessary—morning bathroom ablutions, for example

    The goal here is to have a this-and-this-and-this-and-this list of items that you can go through without any deviations, and get in the habit of “after item 1 I automatically do item 2, after which I automatically do item 3, after which…”

    Implement this, and your mornings will become practically automated, but in a joyous, life-enhancing way that sets you up in good order for whatever you want/need to do!

  • Is it OK to lie to someone with dementia?

    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 was disagreement on social media recently after a story was published about an aged care provider creating “fake-away” burgers that mimicked those from a fast-food chain, to a resident living with dementia. The man had such strict food preferences he was refusing to eat anything at meals except a burger from the franchise. This dementia symptom risks malnutrition and social isolation.

    But critics of the fake burger approach labelled it trickery and deception of a vulnerable person with cognitive impairment.

    Dementia is an illness that progressively robs us of memories. Although it has many forms, it is typical for short-term recall – the memory of something that happened in recent hours or days – to be lost first. As the illness progresses, people may come to increasingly “live in the past”, as distant recall gradually becomes the only memories accessible to the person. So a person in the middle or later stages of the disease may relate to the world as it once was, not how it is today.

    This can make ethical care very challenging.

    Pikselstock/Shutterstock

    Is it wrong to lie?

    Ethical approaches classically hold that specific actions are moral certainties, regardless of the consequences. In line with this moral absolutism, it is always wrong to lie.

    But this ethical approach would require an elderly woman with dementia who continually approaches care staff looking for their long-deceased spouse to be informed their husband has passed – the objective truth.

    Distress is the likely outcome, possibly accompanied by behavioural disturbance that could endanger the person or others. The person’s memory has regressed to a point earlier in their life, when their partner was still alive. To inform such a person of the death of their spouse, however gently, is to traumatise them.

    And with the memory of what they have just been told likely to quickly fade, and the questioning may resume soon after. If the truth is offered again, the cycle of re-traumatisation continues.

    A different approach

    Most laws are examples of absolutist ethics. One must obey the law at all times. Driving above the speed limit is likely to result in punishment regardless of whether one is in a hurry to pick their child up from kindergarten or not.

    Pragmatic ethics rejects the notion certain acts are always morally right or wrong. Instead, acts are evaluated in terms of their “usefulness” and social benefit, humanity, compassion or intent.

    The Aged Care Act is a set of laws intended to guide the actions of aged care providers. It says, for example, psychotropic drugs (medications that affect mind and mood) should be the “last resort” in managing the behaviours and psychological symptoms of dementia.

    Instead, “best practice” involves preventing behaviour before it occurs. If one can reasonably foresee a caregiver action is likely to result in behavioural disturbance, it flies in the face of best practice.

    What to say when you can’t avoid a lie?

    What then, becomes the best response when approached by the lady looking for her husband?

    Gentle inquiries may help uncover an underlying emotional need, and point caregivers in the right direction to meet that need. Perhaps she is feeling lonely or anxious and has become focused on her husband’s whereabouts? A skilled caregiver might tailor their response, connect with her, perhaps reminisce, and providing a sense of comfort in the process.

    This approach aligns with Dementia Australia guidance that carers or loved ones can use four prompts in such scenarios:

    • acknowledge concern (“I can tell you’d like him to be here.”)
    • suggest an alternative (“He can’t visit right now.”)
    • provide reassurance (“I’m here and lots of people care about you.”)
    • redirect focus (“Perhaps a walk outside or a cup of tea?”)

    These things may or may not work. So, in the face of repeated questions and escalating distress, a mistruth, such as “Don’t worry, he’ll be back soon,” may be the most humane response in the circumstances.

    Different realities

    It is often said you can never win an argument with a person living with dementia. A lot of time, different realities are being discussed.

    So, providing someone who has dementia with a “pretend” burger may well satisfy their preferences, bring joy, mitigate the risk of malnutrition, improve social engagement, and prevent a behavioural disturbance without the use of medication. This seems like the correct approach in ethical terms. On occasion, the end justifies the means.

  • The Big Book of Kombucha – by Hannah Crum & Alex LaGory

    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.

    If you’ve been thinking “I should get into kombucha”, then this is the universe prompting you, because with in this book’s 400 pages is all the information you need and more.

    Because, it’s understandable to be wary when starting out, from “what if my jar explodes” to “what if I poison my family”, but the authors (and photographer) take every care to ensure that everything goes perfectly, guiding us through everything from start to finish, including very many high-quality color photos of what things should (and shouldn’t) look like.

    On which note, that does mean that to enjoy the color you should get a physical copy or Kindle Fire, not a Kindle e-ink version (as then it’d be black and white).

    There’s also a comprehensive section on troubleshooting, as well as hundreds of recipes for all kinds of flavors and occasions.

    Bottom line: in the category of books that could reasonably be called “The Bible of…”, this one’s the “The Bible of Kombucha”.
