A bias source that uses non-bias sources to back up their claims. Do I agree wholeheartedly with every claim? Nah. They stretch it a little bit, but the overall message is factual and based on the available evidence.
They stretch it a lot on some of them:
Many people die from alcohol use. Nobody dies from marijuana use.
You can die from alcohol poisoning. There is no known LD50 (lethal dose for 50% of the population) for marijuana. So it's true that you can't die from a marijuana overdose, as far as we know. But that's not quite the same thing as saying you can't die from marijuana
use. You definitely can, and you can do so the same way you can die from alcohol use without overdosing: drive while intoxicated and get into a fatal accident. I don't know the numbers (and they might not be accurate: it's much easier and cheaper to test for alcohol than marijuana so the former gets more testing), but I seriously doubt it's zero.
Alcohol use damages the brain. Marijuana use does not.
That is wrong. Marijuana use
does damage the brain. In particular, it leads to an
earlier onset of psychosis. Although alcohol abuse can lead to other forms of brain damage, it does not appear to lead to earlier onset of psychosis.
Alcohol use is a major factor in violent crimes. Marijuana use is not.
To quote a bit more: "By contrast, the government does not even track violent acts specifically related to marijuana use, as the use of marijuana has not been associated with violence."
The logical flaw is obvious: if you're not tracking it, how can you tell that it's not a factor? Well, you can't. And this gets back to an earlier point I made: testing for marijuana is more difficult, more time-consuming, more costly, and more invasive than testing for alcohol. Police are much less likely to do so for this reason alone. They don't need a warrant to make you take a breathalizer test if they suspect you've been drinking & driving, but there is no breathalizer test for marijuana, that requires a blood sample, and that DOES require a warrant. Now, I don't really want to give the police permission to take blood samples without a warrant, but given that they can't, equivalent tracking of marijuana's relationship to crime like they do with alcohol simply isn't possible. And the absence of evidence (which we don't have because we never collected it) is NOT evidence of absence. We simply don't know how much marijuana is connected to violent crime. I
suspect that it's less than alcohol, but you really can't say that it's zero, because we don't know that it is.
Now, none of this means that marijuana is worse than alcohol. In fact, even if it is, legalization may still be the right thing to do. But marijuana is NOT harmless. It does harm. The question is if it does
less harm than its prohibition. I suspect so, but it annoys me to no end when people pretend that it does no harm.
