Propylene glycol is one of the main components used in the nicotine solution in our COMPETITORS products. It has been approved by the FDA for some products, including makeup, but is also used in products such as radiator fluid (coolant). Since the FDA has only done minimal testing on the inhalation of all e-cigarette solution varieties, concerns have arisen over certain ingredients used and their adverse health effects for human consumption; especially in comparison to traditional tobacco cigarettes.

Thorough FDA and Independent testing has not been performed on the safety of inhalation of Propylene glycol being vaporized and inhaled, but there have been reports of negative effects, including allergic reactions to the substance that can include nausea, dizziness and more.  Industry research indicates a higher frequency of adverse reactions to it than a vegetable based solution.

Since this is a concern, PROSMOKE DOES NOT USE PROPYLENE GLYCOL as the base of its flavored cartridges. We use Vegetable Glycerin as a substitute for Propylene Glycol, which due to the health concerns, we consider to be a better product while continuing to give superior performance and vapor production.  Hundreds and hundreds of hours of research has gone into making the ProSmoke solution the best on the market!  In comparison to PG.  VG produces more vapor and does not irritate your throat while still giving you a great smooth "throat hit". 

As both VG, PG and other e-liquid variants continue to undergo more thorough testing, ProSmoke will always be in forefront of the market and choosing what we feel is the best solution for our customers.  Although both are currently used successfully in our industry, when given a choice between the PG chemical compound and our vegetable based liquid, customers overwhelmingly choose ProSmoke!
