my mom and dad smoked since I can remember, fairly openly...but they never smoked with me until I was 18 and had my own apartment. I wouldnt say I am messed up now because I saw my parents getting high, but I am glad that they waited until I was an adult to smoke with me because I always had strong parental guidance. When kids start drinking and stuff with their parents they get a mixed message about right and wrong. Parents need to stay parents until their kids are grown up.
