Because it should be a choice.
FWIW, I stopped smoking weed on September 2 of this year, after about 45 years of smoking. I’m 65 and I couldn’t justify it anymore. It was affecting my BPM. It wasn’t hard to stop. The dark circles under my eyes are gone. When I inhale I can tell a difference.
It was a decision based on my own self-interest.
I'd be cool with anybody doing any kind of drug he wanted as long as we get rid of welfare. As long as I'm on the take for other people ruining their lives, as often happens with drugs, it's my business. Make it none of my business then I'm cool with people playing with drugs.
