In terms of community, the living circumstance of teenagers is quite important. The accessibility to the drugs of the neighborhoods and the degree of awareness of forbidden drugs are the influential factors for the teenagers. I think the influences can be good or not, it can be imagined that if the young people with drug abusive tendency live in positively active neighborhoods, the possibility for them of transforming into the drug abuser is still quite low, therefore neighborhoods can play the vital roles as the positive reinforcement for the possible deviant behavior of the youth.
