Can I use it in Vape?

Vaping CBD is perfectly fine, but you must make sure you are vaping an oil mixture that is intended to be vaped. Most tinctures are not good to vape and should only be used to ingest. Tinctures with MCT oil, vitamin E, olive oil etc are potentially toxic and should never be vaped. However CBD can be mixed into blends of PG and VG (Polypropylene Glycol, and Vegetable Glycerin), and vaped without serious risk. (This topic is extremely hot right now, and should be handled delicately, or not at all)
