Extracting pure THC

It's easier than you might think to extract high purity THC from Cannabis. Whether or not pure THC is as enjoyable or therapeutic as full cannabinoid/terpene extract is another subject, but some people may like a clean THC effect sometimes. Well I found a patent that explains how to turn the THC acid in a crude non-polar solvent extract into the sodium salt, which is water soluble and can then be removed in water. Once you have the THCA salt you can then convert it back to THCA and decarboxylate it to THC.

Unlike in the patent text, you wouldn't just throw away the solvent extract that you started with, because there is some THC and other cannabinoids in it. You could use it to make a cheaper type of oil I guess, for edibles mainly. Also you would simplify the process from how it's done in the patent examples. You don't need to do all that stuff if you're just trying to get maybe 95% pure THC. I would also use a quicker decarboxylation method than refluxing in alcohol for 10 hours. Seems pretty slow. This article says that 110C for 110 minutes (easy to remember) produces best results. That's with no solvent, which is easier than refluxing in solvent.

I dont have the patience to read all of that right now but the end result was 99.7% thc. which is pretty cool but based off of what I did read its not easier than I expected. also thc does not taste good when smoked by itself. I know someone who had some stuff that was tested at 93% thca and it tasted terrible.
