It's a shame that the money corrupts the truth, then again cannatonic seems like a wonderful strain.
This web-site has some great CBD information

From another page:
Quote: To Project CBD: I am growing/have a limited supply of Pineapple Thai, a high CBD strain. Do you know anyone who has an interest in obtaining some for study? I am in Southern California. I had it tested at the WercShop and is the result: 2.31% THC / 5.21% CBD. Would someone be interested in them? They will be outdoor organic. I am totally legal, licensed.

Not sure what WercShop is but maybe its a place to find some analysis that may accept mailed samples depending on where in the world you are.
One remarkable strain that I have not heard if it's made it to U.S. shores yet or not is "Avidekel". Supposedly it will be the next big thing.

Tincture is best for not getting too high in my opinion. It can go straight to the skull but it has a more body effect IME. Over-all though if a CBD ratio is high enough it will nullify the majority of the 'high' from the THC and other active cannabinoids. It still may knock a person on their proverbial ass but the high wouldn't be overwhelming. Ideally of course...
Sadly the isolation of CBD isn't too easy. As infundibilum has said it usually requires column chromatography. It has been rumored to be a difficult separation as well. Endlessness mentioned "preparitive TLC" in a thread but I fear it would take a window panel size TLC plate to yield a few grams. if you need tips on this PM me and I'll see what I can find for you by way of journal article's and will be practical.
On thinking about destruction I don't see it as a viable route either as just about anything that would wreck THC would also wreck the CBD.
Hopefully your friend get's better I hear medicinal mushrooms have been known to stump tumour growth and such, know you're fresh on all that though. Peace.
