You tell me. You are sitting at home watching the cartoons you say you enjoy, and smoking your dope in this infantile way. Who has arrested you? Who has made you a criminal?
While I have not been bothered, under the law, I could be bothered for not harming anyone. If I'm smoking a joint while driving - lock me up. If I give your kid pot - lock me up. If I'm smoking MJ in the city park - lock me up.
However, why should it be illegal for me to do an activity, when it does not harm you and yours. The point here is that I can be arrested for not harming a single person. I find that to be immoral. Do you not agree?
