best options are edibles oils and dabs.
dabs are a far safer and cleaner smoke (if the dab is made correctly and clean) than any bong with filtration could ever be. with dabs you are not smoking all the fats waxes lips and sugars that are in the flower. you can also control the temperature of the dab in order to max out proper terpene and cannabinoid delivery. you could also learn to micro dab and find out exact dosage that suits you. along with finding the strain that matches you....you would find yourself quite shocked at how so little can go so far.
there is also no comparison between a dab and a bong hit in regards to the reward(high) you get.
have you ever tried properly made edibles ? tincture drops ?
