what about oil? the oral stuff...
If you are asking about CBD tinctures and sublinguals, there are a lot of high quality products available. There is one vendor I came across, both for vaping and tinctures, that I just can't stand the flavor profiles of, but check out "For the People / FTP" CBD as an example. It's full spectrum phyto-good-shit CBD all testing <0.3% THC, with the extraction processes being so refined and clean, that you might as well be drinking pure organic juice-cocktails.

2-extraction methods are one helluva fucking thing.
