Vape Additives that Mimic Nicotine Are Potent—and Largely Unregulated

A new synthetic nicotine, Metatine, similar to traditional nicotine, has entered the U.S. vaping market, evading FDA regulations. Concerns arise as studies suggest it may be more potent and harmful than nicotine. Researchers worry about mislabeling and lack of data on its effects when burned or metabolized. Calls for regulatory action urge caution due to potential risks and loopholes in current laws. Experts emphasize the need for thorough scientific evidence to ensure public health protection. The FDA is funding research on nicotine analogs but acknowledges a lack of comprehensive data. Authorities face challenges in defining and regulating these emerging products amid growing concerns.
