— — Nicotine salt, a popular nicotine-replacement product, converts to nicotine salt in just a few minutes when it is blended with nicotine juice.
It is cheaper and easier to purchase, and it is less toxic than its competitors, according to the FDA.
But when a smoker mixes the nicotine salt with nicotine liquid, the result is nicotine salt which is far more toxic than the nicotine liquid that is blended.
In the United States, the FDA says, the risk of a nicotine overdose is higher when smokers mix nicotine salt or nicotine juice with nicotine, compared with when they mix nicotine juice alone.
The combination is a deadly combination.
Nicotine salt is not the only nicotine-delivery product on the market that converts to vapor.
Many other flavors are also being marketed to replace nicotine in the smoke of cigarettes, but the FDA is warning against mixing those flavors with nicotine salt because they have been linked to more nicotine-related deaths.
The FDA also has not issued any safety guidelines for those products.
Instead, the agency is asking for input on how to limit the risks to people who mix nicotine with nicotine.
The safety of those products is being examined as it considers how to set safety standards for nicotine delivery products.
Nickel-containing products are available at a wide variety of retailers nationwide, including Walgreens, Rite Aid, CVS and Wal-Mart.
Some have already started to test the safety of these products, such as in a pilot project in Minnesota, and the FDA will look into whether those tests will produce an effect.
The agency has previously said it will review the safety effects of these nicotine-containing and nicotine-salt products to determine if they can be regulated as safe products.
The first safety assessment of these new nicotine-containing products will begin in August, when the FDA issues an initial safety alert to the public.
A second report on the safety status of the nicotine-dispensing products is expected in September.
The new nicotine products, including nicotine salt as well as nicotine juice and nicotine replacement products, are marketed under various brands, including NICEV, NICEK, NIGEL and NIX, the company said.
