Non nicotine vape

Compared with nicotine-containing e-cigarettes, the main difference of nicotine-free e-cigarettes lies in the absence of nicotine, which means they do not cause physical dependence.
However, it is not harmless "healthy steam". The aerosol produced after it is heated still contains various potentially harmful substances. Therefore, the main risk of it lies in the act of inhalation itself, rather than addiction.
??️ The working principle and main components of nicotine-free electronic cigarettes
It is powered by a battery, which heats the e-liquid to produce aerosol (commonly known as vapor) for inhalation by the user. The e-liquid is mainly composed of the following substances:
Propylene glycol and plant glycerin: The base liquid used to produce smoke.
Spices and seasonings: Offer various flavors such as fruits and candies.
Preservatives/Sweeteners: Such as diacetyl, which may cause lung diseases.
Impurities or contaminants: May include harmful heavy metals such as lead, nickel, and cadmium.
⚠️ Hidden risks: Not just "no nicotine"
E-cigarettes without nicotine can also give rise to various health risks when heating the above components, which are not as harmless as claimed.
Risk Categories Specific Manifestations
Respiratory System Damage Stimulates the airways, causing coughing and inflammation; increases risks of bronchial asthma, chronic obstructive pulmonary disease, etc.; ultra-fine particles in the smoke can penetrate deep into the lungs.
Cardiovascular System Impact One use can damage the inner walls of blood vessels, resulting in reduced blood flow; increases risks of arrhythmia, hypertension, and heart disease.
Potential Carcinogen Exposure High temperatures cause the decomposition of formaldehyde, acetaldehyde, etc., which are primary carcinogens, increasing the risk of cancer.
Heavy Metal Pollution Components of the atomizer release heavy metals such as lead and nickel, which can be inhaled into the body.
Gastrointestinal Impact Animal studies show it may cause oxidative stress in the liver and changes in fat metabolism.
Other Risks Some products claiming to be "0 nicotine" have been found to contain nicotine upon testing.
In addition, e-cigarettes may also bring physical safety risks such as equipment oil leakage and battery explosions. The second-hand aerosols produced by them may also pose hazards to others.

Regulation of non-nicotine e-cigarettes is tightening rapidly.

By the end of 2025, the State Council has more explicitly demanded a severe crackdown on illegal activities such as "e-cigarettes without nicotine", and has urged e-commerce platforms to strictly review such products.
