CBD oil is available in the UK now. Holland and Barrett's just started selling it recently. Although the product I got isn't very strong, at 2.75%. And expensive compared to online sources, which I'd suggest to use.
Decided to test the crude CBD oil from the health food shop for antiinflammatory/pain reducing effects, because I've just found a source of anhydrous 99.98% CBD, the balance being mainly tracesof caryophyllene and possibly tetrahydrocannabivarin and phellandrene, maybe. But not enough to be of any importance. Can get it at a cost of IIRC about $45 US per gram. And in 1, 10 and 50g lots. Which could make it worthwhile, and a lot more practical compared to growing herb, albeit with the proviso that it means working with boron trifluoride, which is highly toxic and water-sensitive, although in the form of its more conveniently handable, non-gaseous lewis adduct boron trifluoride etherate. The isomerization ought to form mostly delta-9-THC, some delta-8-THC (less psychoactive than delta-9-THC but a couple of hundred times as effective as an antinauseant, somewhat around 50% as potent as a psychotropic as D9-THC AFAIK) and the balance being, after purification, some unreacted cannabidiol/CBD, which isn't a bad thing, as CBD helps mellow out the more hallucinogenic/wiery effects or any edginess or anxiogenic effects from THC.
So the result ought to be a nicely rounded mix, of semisynthetic origin, that unlike the typical completely artificial 'synthetic cannabinoid' type compounds, actually matches the properties of pot, because it'll be the same natural cannabinoids, albeit brought into existence through clever artifice. Time taken, a couple of hours, compared to waiting months for plants to grow.
That kid though, he'll now be able to get the stuff in the UK without risk. Although buying online will be a better way than in bricks and mortar stores, because higher quality products are available. And far cheaper. Plus things such as CBD oil designed for use in a vape pen.
