It hasn’t been extensively studied… but, yeah, it pretty much can be.
1 - Marijuana is statistically less addictive.
2 - Marijuana is nearly impossible to overdose on. But I could get enough alcohol to overdose on right now for $25.
3 - Studies show alcohol has more long term negative health consequences such as liver disease, and damage to the brain.
The fact that we can watch tens of thousands (some sources claim over 100,000 people) die every year due to alcohol, in a perfectly legal manner, but marijuana is not considered to be in the same vein of substance or even less damaging is pretty laughable to me. 3,000,000 people die across the world every year due to harmful use of alcohol.
