So this week at work, I started helping out with the juvenile group! All the kids that attend use drugs or alcohol, their ages range from 12-17. I'm really excited about helping these kids out, however I am a huge pothead. I will never let these kids know that, they also can't know that I support medical use. I am totally against kids using drugs, even pot. With 4/20 coming up, we will be having a marijuana debate during one of the group meetings. I need to find info that states legit reasons why pot should remain illegal, damn did I just say that!? Lol. I have to beable to keep it together around these kids. Can ya'll think of any reasons that pot should stay illegal?
