Pretty basic, but still good. Regarding the "Gateway Myth", I always say anyone who desires to try more drugs already has that opinion in them. It's the reason why they decided to try weed in the first place. That's what I say to my mom because her constant arguments are that it's a gateway drug and i makes you a couch potato. Sometimes she'll mention crime/danger. I'm like Mom, weed doesn't make you want to kill anyone or be abusive. Then she says "Well, probably because they don't want to get off the couch."
