I know some don't think marjuana is that bad and maybe it's not for some but it was a total gateway drug for my son who ended up a heroin addict. I just think it makes some people lose all motivation. It's not the same marjuana that was around years ago either. I think you are doing the right thing and should be super hard on your son, I never let my son face any consequences when he was young and who knows maybe he wouldn't have ended up this way if I had.
