Hemp is marijuana. It is also found in the buds that you can smoke to get high. I believe they are somewhat competing components and their concentration depends on when you harvest a plant. It has either more THC/CBD depending on the time chosen.

Didn't know doctors prescribe it. Hemp is relatively closely related to nettles, which are also used for some therapies for arthritis. Maybe there is another component that helps? Could be a coincidence of course.

Cbd is generally derived from hemp (which is legal federally in the us) not marijuana

oh, true. found some pro marijuana sites that said it came from marijuana, but per more reputable sites it's just contained in marijuana, but derived from hemp. Thanks!

The difference between "marijuana" and "hemp" is only legal, not biological, so a distinction without a difference. Hemp growers use a variety bred to have little THC in it. The species is the same.

The species is the same but it is a biological difference, in the same way that a Chihuahua and a Wolf are genetically the same species but in fact quite different.

Well now I’m doubly wrong.
