I think it's more like, most people who smoke it do not end up in trouble (like most drugs actually) the problem is the whole anglo culture around it, being taboo makes it harder to educate people about proper use of it, just saying don't do it is both stupid and irrealist, you should not expect to control everybody's behaviour with drugs.
Plus putting people in prison for getting high cost a lot of money, it also is not applied in the same manner to everyone.
Baiscally, most pot smokers do it in a manner that is completely transparent to anyone who is not there to witness it, like most illegal drugs, it's much less thangerous than alcool.
Also, I had some surgeries, the meds the docs prescribe you after it to control the pain have horrendous side effects, last time I just got some Mari instead, I felt better and did not risk getting addicted to it AND it was cheaper, despite not being covered.
Calling it "bad" is judgemental and causes way more harm than trying to make sense of it and making sure education around it is sensible, there is no need to be drastic about these things, people who have consumption problem should definitely get help, but that's a medical problem, not a legal problem.
