I'm just starting to get into vaping after a friend showed it to me. I don't smoke cigarettes so I'm not looking to have any nicotine in my liquids. I just bought a few flavor drops from capella. I'm wondering if I can just vape the flavor drops by themselves without adding anything or if I am supposed to mix the drops with some pg and vg first? The flavor drops say they already have pg in them and they are water soluble so maybe I just have to mix some vg with the flavor drops so I can get more smoke.
