threads I read, firecrackers work quite quickly, as in 1/2 hour to 1 1/2 maximum... Honestly, I'd eat right before you go into the airport get some gum or whatever and itll hit you right when youre ready to settle into your seat ont he plane, perfect IMO. i wouldnt want to be blazed as shit in the airport... I mean fuck man, I can't find a bag of chips in my kitchen when stoned so if you're in an airport... who knows where you'll end up. That is, if you don't get too distracted by the food court and its plethora of munchies...
