 Microdosing has become a cultural phenomenon. One of the issues we've had is we have all these surveys that ask about substance use, but they don't ask about dosing. Which is why Leis used Google search history to gauge public interest. He found microdosing-related searches grew by more than 1,000 percent between 2015 and 2023, and that in recent years, interest in psilocybin outpaced LSD.
