March 2015 Note: I’ve written a newer article detailing a more advanced extraction method which produces much stronger e-liquid than this method. I recommend you follow that guide instead!
With e-cigarettes exploding in popularity, many people are curious if it is possible to create a cannabis infused e-liquid. Fortunately, the process isn’t that hard, and this recipe can be used to make a cannabis e-liquid that is compatible with most major e-cigarette models.
What You’ll Need
In order to make your own e-liquid, the first step is to acquire the neccesary ingredients, which I’ve listed here:
- Food Grade Propylene Glycol (Available here on Amazon)
- 5mL Dropper Bottles (Amazon Link)
- Food Grade Vegetable Glycerin (Optional, see below. This stuff is good!)
- Cheesecloth to strain the finished product (you can also find this on Amazon, look around for different lengths).
- Any e-cigarette with a cartomizer (such as the Evo-D). I’m currently a big fan of the V2 Pro Series 3 (take a look at my review here!) with its magnetic connections and solid vapor production.
Once you have all the necessary materials Next, place some PG (I used 400ml) into a pot and then place finely ground bud (14g -fairly strong) into the PG. Set the heat to low and let it simmer for 6-8 hours, stirring occasionally. Much like edibles, the potency of the liquid depends on the ratio of bud to PG you use, and I recommend experimenting to see what ratio works best for you (and take it slow when testing!). After you’ve let the mixture simmer, let it cool and then filter out any sediment by using a nylon strainer. Place the liquid in individual dropper bottles, and then try it out by placing a few drips inside your ecig. The finished result is unflavored and produces very little actual vapor (if you want vapor clouds, add some vegetable glycerin to the mix (up to 50% for big clouds of vapor), but this won’t make the liquid any more potent.
If you want, you can also flavor your mixes with various ecig flavors which can be purchased online. In my experience, larger batteries (1000mAH) such as the eGo-D tend to work best for this, as well as dual coil atomizers. Also make sure to pick up some spare atomizers, as I find that cannabis e-liquid tends clog atomizers easier than regular e-liquid does.
The upside to using an e-cigarette tincture is that its produces virtually no smell when in use, and the e-liquid is much easier to store and work with than loose leaf or concentrates are. I’ve also heard reports of people saying that using an e-liquid can increase your efficiency allowing you to save bud. Finally, always remember to be safe and store the liquid in a secure place, with a clear label saying “Not intended for human consumption” !
