I have a libertarian attitude when it comes to recreational drugs. I think for the most part they should be legalized or decriminalized for adults and people should be able choose to fuck up their lives if they want to. The sociological literature has convinced me the War on Drugs just costs everyone. However, I don't actually think anyone should use drugs if they want to be the best person they can be.
When I speak of drugs I am including tobacco, alcohol, weed, coke, heroin, etc. AND the vaunted entheogens (a fancy name for hallucinogens). I don't even date people who drink caffeine regularly. When I read someone's OkCupid profile and it lists “coffee” under the “Six Things I Could Never Do Without” Category, my translation is, “I am a person who is unhappy/unhealthy enough that I am addicted to a substance to give me feelings of aliveness and purpose and I'm proud of that and not going to do anything about it”.
