I one thing that would help at the federal level is a dosage guide, similar to how alcohol works. The drink equivalent is a useful starting point for beer, wine, and spirits. There isn't a "normal" dose, so everyone just asks their friends, and the people they get advice from are generally regular stoners with a much higher tolerance. I've had to argue with someone to convince them that 10mg from an edible is a very high dose for most people. I fortunately convinced the guy who wanted to try for the first time to take 2.5 and just set how that works for the evening
