maaan i use to smoke out maaan, get stoned as much as i could, like sneak extra tokes on the joints and stuff it was great, and then i started to tolerate mroe weed and i fought damn thats bad, i stopped for about 2 months and then started up again and i felt the exactly same feeling as i first felt, trust me the feeling never goes but when you do it on a regular you get use 2 it so u think the weeds not as good or something, stop for a while and then start up again and its like your amateur lungs come back
