Alcohol causes over 2.5 million deaths a year and is legel. Marijuana causes 0 and is illegal.

Alcohol causes over 2.5 million deaths a year and is legel. Marijuana causes 0 and is illegal.
If alcohol is more dangerous than marijuana, what’s the logical justification for one being legal and the other illegal?

If we were making laws for a planet whose population had never experienced either marijuana or alcohol, and we had to choose one of the two drugs to make available, there would be a strong case for choosing marijuana, which has lower organic toxicity, lower addictive risk, and a much weaker link with accidents and violence.

But that’s not the planet we inhabit. Here on this planet, alcohol has been an ingrained part of many cultures since the Neolithic revolution (which may have been driven in part by the discovery that grain could be brewed into beer). People have used cannabis plant products for thousands of years, but its widespread use as an intoxicant in the United States is a phenomenon of the last hundred years. Even today only about one in sixteen American adults used marijuana at all in the course of a typical year; for alcohol, that figure is more than half.

History matters. Custom matters. Practicality matters. Even if there were public support for it, going back to Prohibition wouldn’t work—without a truly ferocious degree of law enforcement—precisely because centuries of tradition and decades of marketing have left alcohol use a deeply ingrained feature of most social systems outside the Islamic world.
