Most people can drink normally, stop at a rational time, and overindulge rarely, if at all.
Most people have a similar relationship with weed.
I don't think that addicts had that tough of a time finding weed when it was still illegal.
CBD is not psychoactive, by the way.
I don't smoke weed, in fact I hate the way it makes me feel. For me it's a non-issue.
For those that are normal drinkers and weed smokers, I think that legal is the way to go, and offer stigma free treatment for addiction for those like us that can't control our use. I don't think the government should decide what psychoactive substances we can put into our bodies. I'm not sure how I feel about legalized heroin and cocaine and meth, but in many ways alcohol is equally addictive.
