Are there strains of marijuana high in CBD but almost absent of THC?

I'm not sure exactly how this works, but you can get CBD as pills with no THC in them.

(Although anecdotally the best results are obtained from taking mostly CBD with a tiny bit of THC; it appears that the latter does something that makes the former's effect more potent. So you see stuff like e.g. 20:1 CBD:THC pills around - can't get high on that, but very effective at pain management. However pure CBD pills are still more common.)

Yes but the trick is mostly just harvesting early.

Yes

Magnesium supplements work very well for many things, too, but are there American insurance plans that pay for it?

Honestly, yes you can but from what I’ve seen it’s the most useless form because it’s the cheapest: magnesium oxide. Good for laxative effects, bad for uptake. I prefer glycinate personally.

Huh. TIL.
