Bloody hell thanks mate but i want to double check because there is quite a lot of scientific stuff there.

1.Smoking Pure MJ doesnt really affect your lungs in a bad way too much
2.Smoking Tobacco does
3.Stoping smoking MJ doesnt
4. and i aint usre about stopping fags
5 can soemoen just quickly sum it all up by saying hwether i am damaging my health by smoking marijuana/tobbaco(in on joint) and cigarretes juts like that (one day i smoke meself crazy the next i didnt smoke and havnt since...) i eman alot of my friends are saying that not giving ym body those chemicals thta it ws so used to so suddenly should be damaging... (but what do they know?) lol thanks all soryr if this seems like hte same question as above but i feel its alittle bit different, and sorry if its the wrong topic i just didnt want to start a new one cos it seemed a bit pointless.
thanks.
