Anyone ever observe whether being sleep deprived affects how strongly marijuana hits people? For example: Swim and his friend smoke about the same amount of bud. I got 2 hours sleep last night Friend got a normal amount of sleep swim and his friend just smoked up I am extremely stoned swim's friend, not so much. Some questions: 1) Anyone swiy's out there who can hold their smoke just as well while tired? 2) Does being tired increase sensitivity to all drugs generally, or just some?
