>Drug addiction is a disease. There's starting to be some pretty good evidence that some people are genetically predisposed to addiction--I think we'll see over the next decade that most alcoholics, drug addicts, and compulsive gamblers have this predisposition. Of course, others use drugs and alcohol to self-medicate for other usually undiagnosed conditions. I doubt most of these people would really choose to live as they do without the underlying condition. When we can treat the actual problem, we'll have a lot more success in the war on drugs.

Drug addiction is "classified" as a disease. It's the only disease I can think of that your choose. You buy or steal the drugs and then choose to ingest them.

>As for homosexuality, I do not believe that people choose to be gay, and pretty much all reputable research supports that. It's still not totally clear whether it's nature or nurture, but by fairly early on, people respond sexually to whichever sex they're attracted to. If it's not a choice, what makes it a lifestyle?
