You can thin the CBD with terpenes, encapsulate it in dextrin, drive the terpenes off with heat, and use the now water-soluble CBD in water with an ultrasonic fogger/oil-diffuser. It won’t precipitate, but the level of solubility is pretty low even with encapsulation, think 100mg per 200ml. The evaporation rate of those units is somewhere like 50ml/hour, which works out to .83mg of CBD being vaporized a minute, or .14mg every 10 seconds. That’s a miniscule rate.
Good article but you didn’t go over the other part of the Amazon problem. There are different grades of hemp extract that contain CBD, you can have 4000mg of Hemp extract but that doesn’t mean it contains close to 4000mg of CBD, full spectrum hemp extract is available commercially in varying grades from as low as 20% CBD. Someone buying a 4000mg bottle could be getting as little as 800mg CBD, this makes a huge difference when trying to compare oils on a price basis. I wouldn’t buy CBD oil on Amazon from a company you cant find for sale outside of Amazon or that doesn’t even have a website. Its a shame because for people looking to experiment with CBD there are so many different companies out there being completely misleading with what they are selling.
As mentioned above, CBD is no longer considered a Schedule I controlled substance under the Farm Act. However, under the DEA’s definition, it remains on the list. This allows for individual states to create exceptions to the status of CBD, even when cultivated from hemp plants grown legally under the act. It also maintains illegal status for any CBD sourced from plants produced in settings that are not consistent with that Act, or by an unlicensed grower. It is expected that more clarification on the status of CBD will come early this year (2019).
