1.I don't think the first hit is the most potent...I try to corner the bowl so someone else can have a green hit too.

2. The bowl in my bong is the perfect size for me smoking by myself, so usually just one. If I'm smoking during my lunch break for school, sometimes I don't finish it, but that just means there's some already packed for the next day's lunch.

3. A typical session for my group is 2 or 3 bongs, then it gets put away
