Has anyone else noticed this effect? after taking shrooms or acid it seems like my tolerance to weed lowers usually for at least a week before it builds back up.

no but im wondering if anti boitics get you higher cuz i only smoked one bowl last night and i dont think ive ever been that high in my life

having sex while smokin is the only way to potentiate.

nah, its just the after glow of the trip, it lasts for a couple days and youll be high as fuck when you smoke.

I havent noticed anything like that. I did acid once and smoked the morning after and didnt feel any higher than I normally would.

I never noticed any such effect. But then I wasn't the most observant person in the world back then....It wouldn't surprise me if it did happen though. Look at the major depletion of brain chemicals you get from tripping.
