I can smoke half a gram of decent weed and be pretty high but then go on to smoke basically as much as I care to and never get smashed
Dabbing hits a lot nicer (preferred) and unless I'm trying to stretch it I'll usually do about 0.1g.
With regards to the edibles, I ate the 2000mg bar and got nothing. After around 8 hours I feel particularly tired but not in a particularly "stoney" way. The bar was sativa dominant 70/30. This was after trying many different edibles in vein, of course. I'm not a complete nut case so the 2000mg bar really was a last resort to see once and for all if I could get high on edibles. Nada
