Sorry, Cannabis Legalization STILL NOT Crazy-Making, Or Deadly For That Matter

The latest fearmongering "Reefer Madness" study is making the rounds now.  This one insinuates (with the requisite hedging of language, of course) that cannabis legalization in Canada might have been linked to an increase in schizophrenia and other psychosis.  But the study doesn't actually say that at all.  A more careful reading of the study reveals that the incidence of schizophrenia proper has NOT actually increased overall following legalization.  Nor does the study actually show that the prevalence or incidence of psychosis in general has increased either (only the vague nebulous category of "psychosis not otherwise specified (NOS)" increased somewhat, and other psychosis diagnoses were not even looked at) for some reason. Natch.

The authors do concede that previous studies on both the USA and Canada have also repeatedly failed to find any significant link between medical or recreational legalization and either schizophrenia or psychosis in general.  But they laughably claim that such studies were too "underpowered" to detect anything.  Riiiiiight.  Perhaps because the supposed effect they were looking for was just noise all along?  

Occam's Razor, anyone?  Point is, if you torture the data enough, they will confess to anything.  And of course, one of the authors disclosed that they personally have ties to (surprise, surprise!) the pharmaceutical industry.

In other news, around the same time that was published, another Canadian study was published in the same journal that found that those who had emergency room visits or hospitalizations listed as related to "cannabis use disorder" were statistically more likely to die in the five years following such admissions.  That study made for some scary news headlines as well, but not only are such patients not even remotely representative of typical cannabis users, but as the requisite linguistic hedging reveals, no definitive casual link could be proven here either.  That is, it was impossible to rule out all alternative explanations even after attempting to adjust for known confounding factors.  

And regardless, clearly this study says nothing at all about legalization.  If weed legalization had somehow resulted in excess deaths in the general population, it certainly would have been all over the news, but it apparently didn't.

It seems like the standards for what gets published in medical and scientific journals these days are really approaching (if not already hitting) rock bottom.  When silly junk science (or approaching junk science) studies like these come out, the very best thing that we can do is to mercilessly mock them as far and wide as humanly possible.

Thomas Jefferson Predicted Exactly Why Minimum Unit Pricing Would Fail

Looks like good old Thomas Jefferson, the third President of the United States and one of America's Founding Fathers, had uncannily predicted long ago why the recent "Minimum Unit Pricing" of alcoholic beverages in Scotland and Wales would end up failing so miserably even on its own terms:

"No nation is drunken where wine is cheap; and none sober where the dearness of wine substitutes ardent [i.e. distilled] spirits as the common beverage. It is, in truth, the only antidote to the bane of whiskey."

And there you have it.  Substitute "beer" or "cider" for "wine" and it still makes just as much if not more sense, especially in the UK.  That is NOT to say that the price mechanism (via taxation or otherwise) is useless, far from it.  All else being equal, we know that higher alcohol prices = fewer alcohol-related problems and deaths, at least to a point.  But the Jeffersonian wisdom above DOES add a VERY important nuance, namely that the RELATIVE price of less-concentrated alcoholic beverages (beer, wine, cider) compared with the more-concentrated distilled spirits (hard liquor) is more important than the absolute prices of either.

Consider this:  the UK as a whole already had, and still has, fairly high but (until recently) very uneven taxes on alcohol to begin with.  Wine and especially cider have long enjoyed lower taxes (and thus lower prices per standard drink) compared with beer and hard liquor there.  Thus, the heaviest problem drinkers, especially poorer ones, often went for cheap and strong cider to get the most "bang for the buck".  Enter minimum unit pricing, a price floor across the board per standard drink which had a much larger effect on raising the price of cider compared with hard liquor.  The unintended consequence?  At least some of the heaviest drinkers likely at least partially switched to liquor as a result, and ended up getting drunker than they otherwise would, with predictable negative effects.

That said, in the USA where alcohol taxes are much lower, especially for distilled spirits, such a price floor may very well be a net benefit overall.  And even in the UK, changing it to a two-tier price floor where distilled spirits would have a higher minimum price per standard drink than non-distilled beverages may very well too.  But as it stands currently in Scotland and Wales?  It's generally pretty weak sauce at best as far as public health is considered.

Oh, and don't ever expect MADD to admit this either.  They have in the past at least half-heartedly called for higher beer taxes, of course, but remained strangely quiet about liquor taxes.  It's almost like someone is greasing their palms, or something.  Nah, that's crazy conspiracy talk, right?
