People ask me all the time if they can make vape juice in the Ardent FX or Ardent Nova decarboxylators. It was not something I had previously investigated because frankly. I personally do not like or use vape pens and vape juice. If I am going to vape, I prefer to vape flowers (click this link to a review of my favorite flower vape). Why? Because we really know nothing about the long term effects of inhaling vape oils. And I also prefer the flavor and effects of vaping flowers.
Nonetheless, I get questions every week from people wanting to use their Ardent FX or Ardent Nova to infuse vape juice. So I contacted Ardent CEO Shanel Lindsay and she said, yes, you can indeed infused vape juice, but it is important to use the right medium.
Most vape juices are made from a base of either Propylene Glycol (PG) or Vegetable Glycerin (VG). As she is known to do, Shanel did lab testing on both. What she found was that vegetable glycerin was terrible at at extracting cannabis, something I had learned while making tinctures (glycerin tinctures will only extract about 1/3 of what alcohol does). However, Propylene Glycol did a good job.
So the bottom line is, if you are going to make vape juice, and this is not something I personally recommend, use Propylene Glycol for maximum potency.
