Well 4-5 hits may not be good enough for you. My friend can take 4-5 hits and not be high (he also has 0 smoking tolerance for quitting for 3 months) and I can be high after the 4th or 5th and smoke everyday for the past month.

I would say nextime you smoke have your friend or you make a home made bong. If you dont know how to make one post back.
