Doblin said salvia isn't "a party drug," "tastes terrible" and is "not going to be extremely popular." He disputes the fact teens are its main users and says older users are more likely.
"It's a minor drug in the world of psychedelics," he said.
Moreover, it's hard to say how widespread the use of salvia is. National and state surveys on drug use don't include salvia, and because it is legal in most states, law enforcement officials don't compile statistics, either.
San Diego State University last year surveyed more than 1,500 students and found that 4 percent of participants reported using salvia in the past year.
