Methods Multiple linear regression was used in order to determine the adjusted association between cigarette smoking among family members, peer network, their interaction and substance use potential. Result Having a sister who smokes (B = 3.19; p < 0.01) and peer network quality were associated with substance use potential (B = -0.1; p < 0.05). The increase in mean of substance use potential associated with decreases in peer network quality score is much more than in who have a sister with a cigarette smoking habit.
