I agree, I just didn't have the emotional energy to go into all the statistics and exacts with the angry young adult from before. Smokin is the most efficient and they are beginning to come out with more devices that eliminate some or all of the negatives. I was talking more from the placenta standpoint of carcinagens versus cigarettes. This kid in college was talking about how smokin while pregnant is the same as blowing it in your childs face. I just needed him or her to understand, that yes, the smoke can be dangerous but the amount you need to smoke to get high truly doesn't create enough smoke, therefore not enough carcinagens (i am not spelling that right, sorry) to make the negatives outway the positives.
