I don't think anyone has claimed it is the organic, original cause of such diseases or conditions, Captain. What most reasonable people know is that it can make situations worse in people with pre-existing pulmonary conditions and can make it easier to pick up bronchitis or other inflammation-aggravated lung conditions. And the truth is, we don't really know what damage cannabis smoke can do. There's not been enough testing, as you know. Why mislead people into believing it may be harmless or even beneficial when no one can accurately say that? I have particular concerns for the members who frequent these boards, many of whom are very young, very eager for unconditional affirmation of weed's medical benefits, and who are not yet fully capable of discriminating what various studies are saying as they will be later when they have more education, maturity, and scientific reading experience.
