I've been smoking for 13 years, most of which has been on a daily basis. early on i used to take a break for 3 months to clean out my system and it was easy to stay off. i smoke at least 6 joints a day now, starting with before i go to work. about 2 years ago i tried to stop and those who are heavy smokers would know that if you abstain from smoking you sweat a lot throughout the night in your sleep, and when I mean sweat, my bed is wet and i have to get up and towel myself off. i can't have a chick over cos once one side of the bed is soaked i have to change sides. anyway, when i tried 2 years ago, i sweated every night for 6 weeks, yes, every single night!!! after 6 weeks i cracked the shits and started smoking again and guess what, the sweats went away. i don't believe it's the grass that made me like that, but more so the chemicals that are used to grow (i don't grow myself).
