Depending on how soon you want to ingest the THC, how you feel about using alcohol, and your ability to acquire a potent source of alcohol (some states in the US sell 98% grain alcohol), you could make a small dose of Green Dragon.
The fastest recipe would require about a shot's worth of high proof alcohol (note: that's an estimation, perhaps you could use less). If you have some time on your hands, you could simply put the shake and alcohol in a closed container away from light (multiple on-line sources say light damages THC) and come back to it in a couple weeks.
If you're anything like me, you probably want to use whatever THC-containing source fairly soon, so perhaps this idea might not be for you. On the bright side, wouldn't it be fun to hide the closed container somewhere and stumble on it a month from now?
There are ways to get the THC and alcohol to join sooner, but the steps are similar to those in preparing THC butter, only more dangerous because alcohol can burn! I think Green Dragon seems like an interesting experiment though. I've never made it myself, so if you are interested I suggest you do some research from a source better than me!
