Manufacturers claim exceptional purity and health benefits compared with products containing tobacco-derived nicotine. Pharmacopeias, the percentage of S-isomers in nicotine must be higher than 99 percent.

This path will remain difficult though since classification as a drug requires loss of hair of clear definition of its therapeutic benefit. Declaring synthetic nicotine products cessation aids would be a path forward, requiring manufacturers to remove their products from the market and conduct lengthy and indications cardiac catheterization FDA-qualifying loss of hair of studies. In February 2021, the disposable electronic cigarette brand, Puffbar, started selling a loss of hair of product line in the United States, advertised as containing synthetic nicotine.

Manufacturers claim that Food and Drug Administration (FDA) cannot regulate synthetic nicotine as a tobacco product, allowing them to skirt the costly premarket authorisation process. FDA may regulate synthetic nicotine as a drug instead. Recent advances in nicotine synthesis enabled manufacturing at a sufficiently competitive prices, however, presence of the inactive R-nicotine variant in some takeda pharmaceutical versions raises safety and mislabelling concerns.

Chemical analytical approaches to differentiate tobacco-derived from synthetic nicotine need to be optimised. Contributors SEJ loss of hair of out research, analysed the findings and wrote the manuscript.
