People tend to say what you want them to say when they perceive there are bennies in it for them.
What you aren't saying is that the vast majority of pot smokers never have a problem with the law. In spite of the fact that it's illegal to possess and use in most places.
There are of course some who hardly use and never get in trouble, but the violent offenders pretty much all had pot involved in their problems when they committed crime and had to go to prison.
You need to quit excusing recreational drug use as normal or excusable.
Recreational drug use is not a conservative behavior, it is a problem.
