Yes, the method of action is very very different between depressants and hallucinogenics. Booze is HARD on your liver and effects most people pretty similarly as we all have similar blood/liver chemistry. With THC and the like, the methods of action are neuro-genic and the habituation/potentiation will change rapidly in individuals. Those receptors are trafficked in and out of the synapses pretty quickly.

Maybe a series of bags would be better. Like with coffee, you have espressos and shots and the like. You can adjust your tolerance fairly knowably and overdoing isn't a catastrophe. But I think the american palette is such that you need a serious foodstuff/snack in size. One gummy bear isn't 'enough' food, you need a bag of them. You can use a rookie-cookie, but sell them in 3 packs or really big discus-like sizes. People want some heft/size and they don't want to leave a half bag to go stale. Then up the dosages in a series. Red packaging is rookie, Orange is a long movie, Yellow is a half day, Lime is enough for a day'trip', Green is a 3-day weekend, etc. Price them all the same so that way it's about the dosage, not the costs.

Find a way to get a stressed out soccer-mom to eat these weed bon-bons like drinking a Cosmo, something instagram-able and dose-able.
