Some people have stronger will power than others. Another things is that the mind set you have when you do the drug will affect it's effects. I.E. your about to trip on shrooms and you keep saying to yourself, "i'm gonna have a bad trip, i'm gonna have a bad trip" 10 to 1 your gonna have a real bad trip. If you do the drug with intention to explore yourself than you will have a great time and you probably won't get addicted. Stop telling he is going to turn into a junkie or he probably will, CannaBliss don't listen to these guys that are doubting you if you believe you can smoke opium without making it your #1 priority then smoke it. I haven't done it myself but plan to real soon, take Not Enough Herb's advice and get some weed and put the opium on top of a bowl of some good herb and plan not to do anything but sit down and chill out....Peace.
