hmm not high with your 5th or 6th time? Make sure what your buying is weed first of all and not something some one is selling you as weed when its not the magical herb we all love ( well, not all of us love the herb , but I sure do ) Anyways next time roll a joint if you can get the papers or try making an apple pipe. And dont take just 2 big hits... take a bunch of your regular sized hits and keep taking those hits until you get high... not just take 2 hits and expect to be high... just keep smoking till you feal it ( although make sure what your smoking is cannabis )
