In my younger days, we always used a water pipe, or bong as it's called. That seemed to be the best way, the least irritating if one has problems with respiratory irritants. Eating it...I tried brownies a couple of times but had difficulties getting past the taste. Was it something we did wrong? Of course way back then the level of THC, etc. in pot was nowhere near what it is today. So we had to probably use way more than one would have to today.
