I was curious if anyone has pursued the combined sport of marijuana and scuba diving. Looking at the colorful marine life and playing with rays and dolphins sounds like a blast. More specifically, the effects of THC in the body under pressure. I've never smoked and scuba dived, but I may smoke the night before or something. There would certainly still be THC in the system. Before I make a 100ft dive, I want to know if I should lay off the stuff for a week or something.
