I agree with Raggytash in that you shouldn't call him an idiot....that word is just so blase and over used....no you should call him something more creative...I for one prefer the term demonspawn when referring to children.

As for his idiocy for getting caught with less than a gram...well, if working on the Guide to Bad Parenting has taught me anything, you have to be creative in your punitive measures...while paddling his butt, may be humiliating for him, (or for you if he just laughs) it just isn't enough.

One thing you could do, is to look everywhere for his stashes when he's not around...and then replace it with oregano....while you keep and smoke the good stuff yourself. Then, he will take his "pot" and smoke it with his friends...and then wonder why no one got high. They'd get pissed at him, for leading them on...and he would be quite embarrassed. Then, every time after you find one of his stashes, you can repeat...it will work until he catches on....be careful, it could back fire. He could pull the same trick on you.
