1. The THC source: The source of THC for this liquid will be extracted oil from vaped bud, stems, trimmings, kief, and anything else i can find. The initial run is just for testing purposes so i don't want to waste good bud to make oil and have it not work. The method that i will be employing for extraction is steeping in pure acetone. I am aware that acetone of an acceptable purity (at least by my standards) is dificult to come buy in the retail market, so i will most likely be ordering it from a lab supply company. I am choosing acetone as my solvent over butane and iso because it is supposed to have a slightly higher yield, and since i am using bud that has already been vaped for the majority of the source, i need to leech out as much as possible.
2. THC Activation: This is a step that i have not seen in any of the other recipes and it is one that i think is completely essential (at least in theory) to get the most out of your product since most e-cigs are designed for vaporizing a nicotine solution and the temperature doesn't get quite as high as i'd like. THC drops its extra COOH molecule and becomes psychoactive and usable at approximately 220 fahrenheit (this is the reason that eating fresh bud, in my experience anyway, does absolutely nothing) My oil will be heated to a temp of 250 fahrenheit throughout so that i can be sure it is completely activated.
3. Solution: After the THC oil has been fully activated, i will add it to a mixture of propylene glycol and grain ethanol (ethanol is for better consistency of mixture since THC is readily soluble in alcohol, and as an added bonus, the alcohol will provide a better throat hit for the vapor). I am not sure what the final ratio of oil to PG will be, but i have read 1tsp. PG to a half gram of oil, so I will Probably start there.
For now this is mostly just for brainstorming and feedback purposes because i do not have enough product to make oil yet, but as soon as i can, i will post pictures and results. In the mean time, comments, suggestions, and opinions are welcome. The process will be a bit labor intensive, but hopefully i will succeed in making a liquid THC product/recipe guide that can be used in any current e-cig cartridge on the market. In addition, if this works, you will be able to add ecig flavorings to the solution and indulge wherever and whenever you want with minimal risk.
Thanks for reading and hopefully i'll be back soon with updates, wish me luck!
Edit: I forgot to mention that this e-juice (provided potency and vaporizing works out) will work in both 3 piece atomizer e-cigs as well as 2 piece cartomizer e-cigs, however i would recomend the 2 piece version because the cartridges are disposable and should not be used more than 5 times with refilling. This will, if nothing else, save you from having to buy new atomizers more frequently and by refilling the used disposable cartridges, the only extra cost will come from the production of the juice.
