CBD vape E-liquid is any e-liquid that nicotine with CBD. Some of them are pure additives that mix in with your existing flavors, while others are pre-mixed blends. CBD is a naturally-occurring cannabinoid found in hemp and cannabis plants, which is shown to provide relief to a wide range of symptoms. Vaping CBD oil is essentially the same process as vaping non-CBD e-juice. If you are using a CBD vape additive, be sure to mix it into your e-juice really well.
