Which would be physically impossible, under normal circumstances. You would pass out LONG before you smoked that much.
Also, weed is somewhat glamorized, but remember, some people don't get much of an effect the first time.
Also, weed is actually pretty good for asthma, it dilates the bronchial passages, whereas smoking cigarettes causes damage and causes them to shrink. Smoking weed actually helps some asthmatic people because of that. However, due to not being used to inhaling smoke, you were probably choking like most new smokers do. I can tell you that LOTS of people choke smoking weed. For me, it's pretty much a given that I need a drink with me (pop, or anything really) when I smoke, because I will choke. If you didn't have a drink with you, if you try it again, make sure to have one.
