That would pretty much have to be the answer to the lung argument.
Tobacco smokers can smoke up to 2 packs per day, or 40 cigaretts. Imagine 40 joints a day! That certainly would increase the risk of lung problems!

Although I feel it should be a social thing, like having a drink, I vote for eating it.
