^the reward system works really well for me.
I don't reward myself with cannabis, i don't even think about it in that way, it's like coffee to me, i have a cup and relax. You aren't going to get a methamphetamine high out of coffee, so why would you get a really intense high out of cannabis? Not to persuade you to use other drugs but you're probably best off tripping every now and then to satisfy that need to get intensely high.
IMO there is no magic to mary, if you take a tolerance break and smoke top quality shit you can be assured you'll be high, and likely anxious/paranoid too. Smoking with a tolerance is a much better high than with no tolerance IME. I guess the exception here is high potency extracts, which will get you insanely high and synth noids, which will as well, but then you're smoking something completely different than the buds of a plant. edibles will also really get you fucking high, they mostly make me sleepy as shit though. so i guess you could try edibles. I don't really believe in the whole tolerance break thing, my tolerance stays the same after daily use and you can only get so high, doesn't matter how much you smoke, even of BHO, you can only get so high from it. Cannabis has its limits.
