So here we have a thread going on 127 post concerning whether the pros and cons of marijuana. I realize some of wish we were 18 again and some of us are still 18, but as other have said it is against FAA regs. Flying is a privilege in this country. You do not have to fly to live, but if you want to fly you have to follow the regulations set up by the FAA. You chose to agree to this when you signed up to learn to fly. The regulations are not secret, nor are they ambiguous, they in fact are quite clear. Unless the FAA decides otherwise, if you want to fly then do not smoke marijuana, if you want to smoke marijuana, then do not fly. Any discussion about the merits of marijuana, whether you can or cannot OD on marijuana, whether marijuana should be legal, whether marijuana is safe, whether marijuana makes you lazy, fat, and unproductive, etc is just flotsam, and probably would be better discussed in the spin zone.
