im 20 now and i smoked with my dad once or twice a couple years ago.but all through my teenage years he was really cool about what i did and was into.he explained very clearly all the drugs and crazy shit hed done when he was my age and toled me he sincerely didnt want me to do this drug or that.and he toled me what was cool.then he toled me why and all the consequenses and things to expect with each drug or drinkin or smoking.he always encouraged me to be open with him about whatever i was doing.he brought me up knowing that he couldnt stop me from doing crazy things but he could educate me on how tough it can be and whats what.as an outcome i never tried anything other than drinking and smoking and never either in abundance for two reasons.my dad did a good job of exlaining the why and also for him telling me everything hes done and how it effected him i wouldnt do more than that out of respect for him...just be honest with your doughter let her know whats ok and why and the why nots.lt her know that she should never be afriad to ask u for help or tell you anything and u cant go wrong...zz
