IMHO if alcohol and nicotine are legal, then anything "soft" that is not particularly addictive should be legal. It's fundamentally unjust to lock people up for using or having substances that are for the most part less dangerous than entirely legal and socially acceptable substances.

Alcohol is actually kind of nasty stuff if you look at the real statistics, especially if used in excess.

I'm not claiming LSD is absolutely harmless, just that it's not physically addictive at all and not nearly harmful enough to merit the harsh criminalization and heavy sentences it receives. LSD can be safe and rather interesting if used occasionally but heavy use or use by people with pre-existing psychotic tendencies can be psychologically dangerous.

My personal opinion is that drugs like LSD should be subject to some kind of licensing regime similar to other hazardous activities like driving a car, flying a plane, or owning and using firearms (in some states). I would also be in favor of blanket bans or at least heavy restrictions on any advertising for drugs, including alcohol, nicotine, and pharmaceuticals.

I disagree. Driving a car or flying a plane can directly harm others, so the licensing process makes sense. Consuming LSD though? It doesn't directly harm others when I consume it.
