No I am not saying the guy who smokes is bad. I am saying his actions cause bad things to happen. Take Phelps I don’t think he is bad or you was bad when you toked. I think he was ignorant of what his actions caused.
If you think it takes six degrees of separation to find an innocent victim of someone using an illegal drug then yes you are ignorant.
I know how supply chains work, so I don't merely think but KNOW that the murder example you're using is at least six degrees separated from the guy smoking a joint.
