Understanding Nicotine Free Vapes

What Are Nicotine Free Vapes?

Nicotine free vapes are electronic vaping devices that produce aerosolized vapor without nicotine, the addictive stimulant found in cigarettes and most e-liquids. Instead, these products rely on flavored liquids made from vegetable glycerin (VG) and propylene glycol (PG).

How They Differ From Nicotine Vapes

The main difference is addiction risk. While traditional vapes deliver nicotine to the bloodstream, nicotine free vapes aim to provide flavor and vapor sensation only. However, are nicotine free vapes safe simply because nicotine is removed? The answer isn’t that simple.

Ingredients in Nicotine Free Vapes

Common Base Liquids

Most nicotine free vapes contain:

What’s Missing Without Nicotine

Removing nicotine eliminates dependency and withdrawal symptoms, but does not remove all health risks linked to inhalation of heated aerosols.
