Our electronic cigarettes contain Nicotine 1.6% per ml. or Nicotine 2.0% per ml. 100% of the Nicotine in our products is derived from tobacco plants. Additionally, our e-cigarettes consist mainly of water, a preservative (pure vegetable glycerin and propylene glycol), and flavoring.
Propylene Glycol – The Food and Drug Administration (FDA) has determined propylene glycol to be “generally recognized as safe”, or GRAS, for use in food. Propylene glycol is also safely used in cosmetics and medicines. It is used in food coloring and flavoring as an additive to keep food, medicines, and cosmetics moist. It is also used in machines that simulate smoke, although usage in simulating smoking devices is not currently included in the list of uses recognized by the FDA. In a 21st Century Smoke electronic cigarette, propylene glycol functions to provide the vapor mist that looks like smoke, and to suspend flavor. Inhalation of propylene glycol vapors appears to present no significant hazard in ordinary applications (Wikipedia Propylene Glycol)
Water – The water used in 21st Century Smoke cartridges is filtered via a reverse-osmosis process.
Nicotine – Nicotine is an alkaloid found in certain plants, predominately tobacco. It is also found, in lower quantities, in tomatoes, potatoes, eggplants, cauliflower, bell peppers and some teas.
Pure Vegetable Glycerol (glycerin) – Glycerol is a chemical compound also commonly called glycerin. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. For human consumption, glycerol is classified by the FDA among the sugar alcohols as a caloric macronutrient.
