Weighing the worth of something you want to buy (but don't need) vs. an equal worth of candy bars
Works in your favor every time, since you can argue that instead of buying fatty sweets you are doing yourself a favor
Does not work if you continue to eat candy
I'm running low on funds, and this bud is gonna cost me $100. Well, shit, that's like 100 king size snickers. Would I enjoy 100$ of weed more than 100 snickers? Fuck yeah! My candy bar theory never fails me.
