to be 100% honest without exagerating, i smoke everyday ar various times. my lungs are in really good shape and i def dont have any problems with low sperm.

i hike and workout as well but as long as you are active you shouldnt have ANY health problems. yeah smoking anything is bad but marijuana can open up your lungs. i also believe a good ammount of tokers larf around eating crap food they call 'munchies'
