Vaping is known to be relatively safe and carries a significantly smaller fraction of the risks associated with smoking conventional cigarettes. On the UK market vaping devices and products are being tightly regulated for health, safety, and quality, while in the USA, these need to be verified and regulated by the FDA before entering the market (since2016).

The majority of products who were suspected of causing lung diseases are being sold off the street and contain various chemical substances (in many cases carcinogenic) such as tetrahydrocannabinol (THC). THC is a psychoactive component of the marijuana plant and no vaping product containing THC has been regulated to enter the market. Purchasing such products from unknow sources could highly affect the consumer. It can cause symptoms such as cough, shortness of breath, chest pain, and in some reports even death.

Vaping products purchased through retail establishments normally contain harmless substances such as PG (propylene glycol), VG (vegetable glycerine), flavour, and/or nicotine. Therefore, to avoid side effects it is important to never purchase vaping products from illicit sources, or attempt to add any other substances, THC, or oils to your e-liquid.
