Well, what I mean is, gnu...

It's unhealthy to eat excessively, drink excessively, smoke excessively, sleep excessively, exercise excessively, watch TV excessively, and do anything else excessively, but you cannot force people to make only the most healthy choices in life by passing laws against all these various things. After all, I know totally responsible and kindly adults, good citizens all, who do smoke marijuana or who smoke tobacco or who drink...but not excessively, and it doesn't cause them to engage in any harmful activities toward other people or toward society in general. They should not be penalized by draconian laws which make marijuana or alcohol or tobacco or anything else like that illegal...because they are NOT doing harm to anyone else as a result of their habit...and probably not much harm to themselves either. So it's their business if they want to grow and smoke their own marijuana. And it's no one else's business.

You have to let adults decide for themselves what to do to themselves in the privacy of their own lives.

As for children, some laws are definitely needed to protect children, and I think we all probably agree when it comes to that.
