Basically, I'm pretty wary of the adverse effects of drugs and becoming dependent on them. I've never done any, including drinking etc. But I'm curious about edibles, since it seems like there's barely any downsides, besides the risk of the edible itself being too potent(?).
The most correct answer in my experience is to buy 10 mg gummys and start with 5 mg. Experiment, like your parents warned you about. 10 mg is also a pretty normal amount to start with. Just know it might take a couple tries to get it right. But it's generally pretty safe, i.e. for most people, you can overdo it by a lot and not be in any medical danger.
