From personal experience, I have vaped RSO oil that I have made. It is important to know how it was produced and what solvent was used for extraction. We use 190 proof non-gmo ethanol…pure alcohol. There are some other people that use other toxic solvents like hexane, butane and many more. Personally I would not want those in my system, so make sure you know how and what was used for extraction. Secondly, because RSO oil is thick like molasses, many vape pens cannot handle the thick oil, so either find a vape pen that can OR thin down the RSO oil with some organic vegetable glycerin, which will make it easier to vape.
