Cannabis Legalization Is STILL NOT Crazy-Making In Canada OR The USA

Reefer Madness? More like Reefer Sanity. Yet another study finds that cannabis legalization in Canada (where the age limit is 18 or 19 depending on the province*) did NOT result in any increase in cannabis-related psychosis.  This dovetails nicely with several previous studies in both Canada and the USA.

In other words, the remaining prohibitionists and fearmongers are looking less and less like Cassandra, and more and more like Chicken Little now.

(*Quebec had initially set it at 18 in 2018, but they raised it to 21 in January 2020, with no grandfather clause.  Alberta remains 18 to this day, and all other provinces are 19, mostly matching the drinking ages.)

Cannabis Legalization NOT Crazy-Making After All

Good news, it looks like cannabis legalization did NOT lead to a statistically significant increase in psychosis as the Chicken Little prohibitionists liked to claim.  And this new study was not done by hippy-dippy stoners, but by serious researchers at Stanford University, who published it in the esteemed Journal of the American Medical Association (JAMA).

Not even recreational retail store sales (i.e. cannabis commercialization) seemed to significantly move the needle in that regard, despite the obvious net increase in cannabis availabilty, convenience, and potency relative to not having such legal retail store sales, and the (eventual) net decrease in price per unit of THC.

And furthermore, when results were broken down by age, the results were totally in the "wrong" direction than the age-restrictionists would have predicted.

OOPS!

Looks like Alex Berenson was wrong about that, yet again.  And looks like Reefer Madness 2.0 was ultimately a flop once again.  Womp womp.

UPDATE:  See also here and here as well for further studies that pour cold water on the Reefer Madness 2.0 fearmongering. 

25, You Say? Let's Nip That In The Bud

A handful of psychiatrists in Minnestota, where cannabis has not yet been legalized for recreational use (but is currently being considered), is calling for the age limit to be 25 when it is legalized.  They cite anecdotal evidence of young patients with psychosis that they claim is caused by today's high-potency weed.  And here is why they are, in a word, wrong:

1. First of all, these psychoses that they cite are occurring despite recreational cannabis remaining illegal in Minnesota for all ages.  Legalizing it with an utterly unrealistic age limit of 25 will only preserve and entrench the current black market while worsening criminal justice inequities, both age and racial disparities.
2. The brain continues developing well into the 30s and 40s, and the risk period for schizophrenia continues until about 30, so 25 is arbitrary.
3. While excessive cannabis use can be harmful at any age, and starting use before age 18 and especially before 15 is likely more harmful than starting at 18 or older, there is really no clear and convincing evidence that using it at 18-20 is any worse than using at 21-24 or 25+, especially for light or moderate use.  To claim otherwise is unscientific, disingenuous, and really pushes the limits of the precautionary principle.
4. As we have noted many times before, the relationship between cannabis and psychosis is quite complex, and far more nuanced than Reefer Madness.  Though there is likely a tiny, exquisitely vulnerable sliver of the population that should really avoid weed like the plague at any age, that is no reason for blanket bans or restrictions (by age or otherwise) for legal adults.  That would be unscientific and unjust.
5. And finally, if today's high-potency weed is in fact the culprit in an alleged (and far from certain) recent increase in psychosis among young people, the solution is NOT to raise the age limit and force it deeper underground, but to put a cap (say, 10% or 15%) on the potency of THC on legal weed (and perhaps also setting a minimum level of CBD, which counteracts many of the adverse effects of too much THC), and/or taxing it based on THC/CBD levels.  And also warn people who are at increased risk of psychosis as well via honest public education messaging without sensational fearmongering.

There it is.  Problem solved.  No good reason to set the age limit any higher than 18, let alone 25.  Let's nip this ageist idea in the bud, pun intended of course.

UPDATE:  Twenty-One Debunked believes that proper labeling and tax incentives alone will likely be enough to encourage lower THC and higher CBD levels even in the absence of hard THC/CBD limits.  Taxing cannabis at a higher rate base on THC levels (whether proportionally, or perhaps disproportionally when exceeding a specific threshold or for specific product categories) and applying an offsetting tax discount based on CBD levels would do the trick, as the market would adjust accordingly.

Also, getting back to the subject of psychosis in young people, don't forget to take your fish oil.  Yes, you read that right.  Apparently a new study found that there is an inverse correlation between omega-3 fatty acid levels during adolescence and psychosis in young adulthood.  This dovetails nicely with a study from 2010 that found that just 12 weeks of giving fish oil supplements to teens at ultra-high risk of psychosis greatly reduced their risk of developing psychosis a year later compared with those given placebo.

The Verdict Is In: Legalizing Weed STILL Does NOT Increase Crime Rates

Recently, the modern-day "Reefer Madness"-type alarmist yellow journalist Alex Berenson has been claiming that cannabis legalization has caused huge spikes in violent crime since 2014 in the states in which it has been legalized.  He then claims that such increases in crime are somehow causally linked to the effects of cannabis (particularly via the putative and controverisal link to psychosis), and therefore to legalization as well.   But both claims are in fact highly faulty and questionable at best:  1) plenty of states, not just legalization states, saw at least modest spikes in violent crime in 2015-2016, 2) violent crime now seems to be decreasing once again regardless of legalization, 3) 2014 is an arbitrary year to choose for the base year given the timing of legalization initiatives, 4) cannabis has never been causally and conclusively linked to violence, except perhaps inversely, and 5) and most importantly, correlation does not prove causation, as so many other variables come into play here.

In fact, the latest studies on the matter have confirmed what the TSAP and Twenty-One Debunked have kinda always known.  Legalizing weed does NOT seem to increase crime rates like the prohibitionists often claimed it would, and if anything, appears to decrease violent and property crimes a bit, as well as improve their clearance rates by police.  For example, researchers found this by comparing the border counties of Washington and Oregon, whose timing of legalization differed but were otherwise quite similar. But we could've told you that years ago, for those actually willing to listen.

The theory for how legalization of cannabis would reduce crime is fairly simple.  First, it frees up relatively scarce police and other resources that would otherwise be used to bust people for weed, and allows such resources to be put to more productive uses (i.e. targeting real crime rather than victimless crime).  Secondly, cannabis is basically a non-violent drug, and can often substitute for alcohol, which is often (rightly or wrongly) linked to violence to one degree or another.  Thirdly, there is the systemic aspect, the violence linked to the illicit drug trade itself, which would self-evidently decrease if not disappear upon legalization, at least with regard to the substance being legalized. And finally, victimless crime laws, especially widely unpopular ones like cannabis prohibition (and, of course, the 21 drinking age) erode respect for the law in general and also erode cooperation and cohesion between the police and the community.  Thus, it really doesn't take a rocket scientist to see how removing such illiberal and pharisaical laws from the books would tend to decrease crime in general.

What about the opposite theory?  Not the long-debunked one that cannabis per se actually causes violent and property crime (which is rather silly on its face, mind you), but the one that claims that cannabis prohibition is a useful crime-fighting tool for police?  Well, as the saying goes, the proof is in the pudding, and we really don't see any credible evidence of that on balance.  Any utility that such an abomination would have in that regard appears to be more than outweighed by its very real downsides, and thus we can consider that theory debunked as well.

(Cue the Law and Order DUN DUN sound effect.)

We need to legalize cannabis in all 50 states and all territories as well, yesterday, and lower the age limit to 18 as well, just like our neighbor to the north.  It is LONG overdue.  So what are we waiting for?

Reefer Madness Redux (Again) Is More Smoke Than Fire

Many years ago in 2011, the True Spirit of America Party wrote an article discussing the highly controversial and complex link between cannabis and psychosis.  Since then, many more studies have been done, and to this day the supposed link (as to whether or not it is a causal relationship) remains as clear as mud for the most part.  That, of course, does not stop the prohibitionist alarmists from harping on it as though it were certain--there is even a recent book (which can be easily debunked) titled Tell Your Children, which interestingly enough, was also the original working title for the 1936 film--wait for it--Reefer Madness.  What passes for discourse on the topic these days has come full circle, it seems.

The most recent study to date is a case in point.  The researchers examined 901 people aged 18-64 who experienced first-episode psychosis at a mental health facility, compared with a control group of 1200 people in 11 cities around the world.  While it still does not prove causation, it did find that 1) daily use of cannabis in general, 2) initiating use before age 15, and 3) use of high-potency cannabis (i.e. above 10% THC), especially when used daily, were correlated with a higher risk of having such psychotic episodes.

And while the three cities with greatest availability of high-potency weed (London, Paris, Amsterdam) had higher rates of psychosis, though this was cross-sectional and cannot establish temporality, a rather crucial criterion of causation.  And interestingly, psychosis rates were higher in London and Paris (where weed is illegal) than in Amsterdam (where it is quasi-legal), so the legal status of cannabis did not really appear to be an issue.  Moreover, it is not clear which is the proverbial chicken and which is the egg.

Paul Armentano of NORML wrote an excellent and in-depth article (with links to other studies) that does a great job debunking this latest round of Reefer Madness 2.0, and is certainly worth a read.  A shorter version can be found here as well.

Additionally, we at Twenty-One Debunked have previously reported on the emerging research suggesting that nicotine may be the real dark horse here in the etiology of psychosis and particularly schizophrenia.  And famously in Europe, particularly in those three aforementioned cities, cannabis is usually mixed with tobacco, especially when it is high-potency and users may wish to stretch it out by giving it some bulk. Though clearly a far less toxic and nicotine-free way to stretch it out is mixing with catnip or even parsley, or just do what most American tokers do:  smoke (or vape) the weed straight up without mixing, but simply take fewer hits, use bowls/bongs instead of joints, and/or seek out lower potency strains.  And in Australia, not mixing with tobacco is about as common as mixing.

And as we have noted time and again, the rates of cannabis use have increased dramatically since 1960 or so in nearly every country, while the best evidence suggests that psychosis rates have generally NOT increased since then.  Thus, any causal link with psychotic disorders that would not otherwise have occurred would most likely be either weak, rare, or both, and thus likely limited to a very, very tiny percentage of the population who are unusually vulnerable and/or ultra-heavy users.  And while some already psychotic users may find exacerbations of their psychosis (or its effects may make a latent or subtle psychotic disorder more noticeable to themselves or others), others may use the herb to self-medicate as well, and everything in between.

Overall, this and other studies seem to be more smoke than fire, and even if causal they do not suggest that the hyperbolic "no safe level of exposure" theory is correct.  Rather, the biggest takeaway from this study is, if you do use cannabis, don't overdo it, particularly with the high-potency stuff.  In other words, moderation is the key.  And while age at first use was one of the lesser factors, delaying use until at least age 15 or older is likely prudent--not just for this reason but for other reasons as well.  And these studies do not really militate against legalization, but rather should be seen as encouraging legalization and proper regulation and taxation of cannabis based on THC and CBD levels.  Nor do these studies support setting the age limit any higher than 18 either (which of course will only encourage the black market to persist).  So we need to see the forest for the trees.

And thus we will finally have Reefer Sanity in this country for once.
