I live in Colorado and they limit edibles to 10mg per piece/100mg per pack max. 150mg for a single gummy is a bit nuts though.
As someone who smokes a good amount of weed, my recommendation to people it to always stick to just flower. I've tried it all, vaping, vaporizers (different than vaping, you're superheating flower rather than using an extract), edibles, and regular pot.
From my personal experience, edibles last the longest but don't hit right away, takes about an hour for it to pass through to your liver and from there I noticed that it was a "low grade" high for a few hours.
Vaping is the polar opposite, the stuff hits you almost instantly. You also have to be careful and not puff to much, a monster hit will send you to another universe. I've also noticed that because of the high THC content (sometimes 90-100%) and virtually no CBD content, this is the easiest way to have a bad high. This also gives you the shortest high, seems to wear off quickest.
Finally you have good ol' flower. This is what I usually smoke because it slots somewhere between vaping and edibles in terms of how high you get. I almost always smoke flower because I get consistent results. If I vape I might have a panic attack, if I have an edible it might last too long, but with plain weed I know how long I'm going to be up, what the experience will be, etc.
Also this is complete pseudoscience but there's something that makes me feel better about smoking flower vs the other stuff. Vaping and all that other stuff is cool, but there's a certain safety in knowing the only modification a flower had was trimming the leaves away, no lab equipment, extractions, chemicals or any of that.
