It’s unusual for a medication to become a household name; even more uncommon for its branding to become, like Advil, shorthand for an entire class of products; and rarest of all, for it to change not just U.S. medicine, but U.S. culture.Ozempic has done all three.Approved in 2017 as a type 2 diabetes medication, Ozempic has largely made its name—and a fortune for its manufacturer, Novo Nordisk—as a weight-loss aid. Novo Nordisk knew early on that diabetes patients often lost weight on the drug, but even company executives couldn’t have guessed how widely it would eventually take off as both an off-label anti-obesity treatment and a vanity-driven status symbol for those simply looking to shed a few pounds.

Settling on an answer to this question has a surprising number of implications: for the internet, for policy (most notably in a recent lawsuit against Meta), and even for people who suffer from or treat more well-defined forms of addiction. Attempts to do so have resulted in fairly conflicting findings, explains Niklas Ihssen, an associate psychology professor at Durham University in the U.K. In particular, some studies suggest abstaining from soci...
