CBD is a non-intoxicating substance that will make everyone feel different. Since CBD is non-intoxicating, you won't feel "high" as if you were to vape something with THC in it. People report feeling positive effects when vaping CBD.
These effects include feeling more calm or relaxed than normal, pain relief, and even feeling like they can fall asleep and stay asleep easier. How you feel after vaping CBD can be dependent on the type of CBD you choose. There are even some CBD vape cartridges that encourage your mind to focus and feel more awake.
