Disclaimer
The content here is a historical record of the e-cigarette market of the 2010s. It is not medical advice, not health advice, and not a current product recommendation.
Nicotine is addictive. These products are not intended for minors, for non-smokers, or for anyone who does not already use nicotine. If you are trying to stop smoking, the appropriate source of advice is a clinician or a national smoking-cessation service, not a review site.
Product specifications, pricing and availability described in any page dated before 2020 are obsolete and should not be relied on. Where a company has closed or a product has been discontinued, pages say so; where we could not verify a brand's current status, the page says that instead of guessing.
Regulation of these products differs substantially between countries and changes frequently. Nothing here should be read as a statement about what is legal to buy or sell in your jurisdiction.
