As nicotine is highly addictive, marketing nicotine-containing products is regulated in most jurisdictions. Regulations include bans and regulation of certain types of advertising, and requirements for counter-advertising of facts generally not included in ads. Regulation is circumvented using less-regulated media, such as Facebook, less-regulated nicotine delivery products, such as e-cigarettes, and less-regulated ad types, such as industry ads which claim to discourage nicotine addiction but seem, according to independent studies, to promote teen nicotine use.

Nicotine marketing is the marketing of nicotine-containing products or use. Traditionally, the tobacco industry markets cigarette smoking, but it is increasingly marketing other products, such as electronic cigarettes and heated tobacco products. Products are marketed through social media, stealth marketing, mass media, and sponsorship. Expenditures on nicotine marketing are in the tens of billions a year; in the US alone, spending was over US$1 million per hour in 2016; in 2003, per-capita marketing spending was $290 per adult smoker, or $45 per inhabitant. Nicotine marketing is increasingly regulated; some forms of nicotine advertising are banned in many countries. The World Health Organization recommends a complete tobacco advertising ban.
