I was introduced to smoking weed when i was about 25. the first few years it's always on a rare accasion. then when i was 27, i was smoking practically every night. just before i go to sleep. in a weird way it helps me to relax. then it stopped. From 28 to 30, no weed. Now i'm 34 and for the last 2 years i;ve been smoking every night and i realised some perceptive damage it did. I have quite completely now. also i have been smoking since i was 19. Now i have given that up as well. since i;ve quit about a month ago... i keep coughing badly. I never had this problem before but only now. all the withdrawal sympthons that comes with quitting smoking have manifested and it's over except this coughing... Any sincere advice...
