Many people agree that, if marijuana is less dangerous than alcohol and smoking (two legalized substances), marijuana ought to be legalized as well. But given that there are plenty of other drugs both less and more dangerous than alcohol, it seems using alcohol as a an arbitrary cutoff point is rather random.
In my opinion, its worth fleshing out our reasoning a bit.
Given there are plenty of arguments for legalizing the recreational use of relatively "safe" drugs, at what precise level of danger do you think drugs should be banned by the government? Should ALL drugs be prohibited/legalized? What other cutoff point would you propose?
