THC absorption from smoking a joint is very poor though compared to other methods. Probably in the range of 25-35% of that 200mg. Regarding potent edibles, I dose my mother close to 800mg a day, using 4x a day 200mg caps that I lab test each run to be sure. I wouldn't give it to someone who doesn't use edibles much, but certainly you can build tolerance and consume very large amounts without ill effect. edot: damn I didn't realize how old that post was lmao.
