Because everyone that takes drugs leads happy, productive lives? There's no magic pill for happiness or "rightthink" and assuming that one side (conservatives) are against drugs because it changes people is really wrong. If you look at the history of the conservative party, you'd see they were very much progressive in moral and social issues. And, in many cases, they still are.
