Around where I am from, blunts typically are packed w/ a gram (weed seems less prevelant here then in other places in the world, so we typically don't pack a blunt with more weed then that). My advice to you is to make sure your blunts are rolled correctly. A lot of times you can get a small hole in them if you roll them carelessly, causing a lot of smoke to leak out of the side of the blunt. Also, make sure you get a good deep hit from the blunt, a good strong hit from a blunt will knock you on your ass.
