Couple methods to add to your lovely post.

Vaporizers: A lovely cost-efficient, easy on the lungs alternative to smoking. You can pack a small bowl (1-2 tokes worth) and it will last a good 10-12 minutes easily of consistent toking, depending of course on your temperature settings.(so plus or minus 5 minutes)

Exercise, few things are better for ramping up the intensity of your high when you have quite the tolerance built up already.
Simply heading outside and going for a run 20-30 minutes after consuming an edible will leave you smiling at the clouds as the aches in your body slowly fade away and the runner's high melds together with the edible into a whole much greater than it's parts!
