Alcohol is absolutely an issue, all drug use is. I don't limit myself to 'some' chemicals. But I'm not sure exactly what you're asking, are you asking if I think drug use ought to be treated the same way, as an environmental and behavioral issue, rather than some individualistic moral guilt thing? Yes, absolutely.

It's a good example actually. We've done incredible damage by moralizing drug use rather than treating it as medical issue and instead promote quackery like AA which has horrible outcomes.
