The risk of using a nicotine-free vaporizer to quit smoking compared to Nicoderm patches is that the vaporizer does not contain nicotine, so it does not help to reduce physical and psychological withdrawal symptoms associated with quitting smoking. Additionally, using a vaporizer may not break the habit of having an object in the mouth, similar to a cigarette, and may pose risks of serious lung illnesses. It is important to consult with a pharmacist to explore other alternatives, such as medications or nicotine replacement therapies, to help quit smoking effectively and safely.
