My uncle Wilbert did the same thing, except he was into harder drugs. He was a pot guy, but then had a dream that pot was legal (he had a hard time with what was real and what was a dream, being a loser pothead and all) and that forced him to move to harder drugs. He was a badazz and couldn't deal with the fact that his favorite thing to do was now legal (making him not such a badazz anymore) that he started doing heroin.
Wilbert met his demise while trying to bumper hitch. For those of you who do not know what "bumper hitching" is.....In Canada with ice covered roads, when a car stops at a stop sign, you run out from behind a bush and grab the bumper and get into a tuck position and ride along for a bit sliding on your boots. Well we had a heat spell and there was no ice on the roads (Wilbert was really messed up that day) Wilberts feet didn't slide and he was dragged behind a car for 50 miles. We also called him skinner. I feel your pain my friend.
