CBD is one of the cannabinoids in weed. Two main ones are THC and CBD. The THC is what gets you "high". CBD has no psychoactive properties.
Very little research into it (both CBD and THC) since it's federally illegal and basically no one is allowed to test, even like the CDC. Pretty retarded.
CBD oil is clinically proven to help with seizures for certain types of epillepsy. One of the few things clinically proven regarding marijuana/hemp. But aside from that CBD can have the medicinal properties of relieving anxiety, headaches, inflammation, pain (I think this is more THC though, not totally sure), can help with sleep, and can help with stuff like depression. But it's really on a case by case basis (anecdotal due to lack of testing allowed) and it may or may not work/help you. Or it may just depend on what form you take (gummy, tinture, inffused), the dosage and your tolerance, or just if you have a quality brand (lot of trash probably). Personally I think if you have a dispensary, there is no reason not to ask and try it. **** pharmacies are allowed to sell CBD that comes from Hemp (low to no THC). And especially if you have gummies already there is no reason not to. Like all you're risking is feeling calmer and maybe less pain. I'd probably start with just taking 2 gummies. Next day if you felt good you can take same dose, if not up to 3 the following day and see how you feel. If even after that you don't feel **** maybe you try a different brand.
Anyways I think for CBD there are two main categories - Isolate which have NO THC (probably comes from Hemp which is a marijuana plant with little to no THC). Basically It's straight up CBD oil, (not sure if you'd be fine taking a drug test with this or not). Then there is Full Spectrum which basically contains all the cannabinioids in the plant. So you will get some THC which could make you feel a little bit of that high. But even then I think it's minimal THC, however I think this is supposed to be "better" for medicinal treatment (definitely would fail a drug test though).
And if you're looking for stuff basically I'd say that anything you'd buy at a normal store but labeled CBD is probably trash/fake. You'd definitely want to either hit up a dispensary or at least go to the pharmacy and see what they got. Real CBD stuff can be pretty expensive, and that's probably a good way of telling if it's legit or not. Those dog treats you buy for your dog labeled CBD are probably bs...
If you were in CA I could probably tell you some actual producers that are good, but otherwise I'll just leave this and you can buy what you think would be good:
