B F Skinner's Behaviour Conditioning comes into my mind when I read this article. Of course the chances of a teen drinking or smoking is very high especially when they catch their parents or guardians. Teenagers spent more time with their peers and definitely if their peers drink then naturally that particular teen will drink. If the teen is near adulthood then there's a chance he or she will know the bad effects of alcohol. TV Ads that is about drinking also should be banned
