Demand for salvia has increased since Miley Cyrus was spotted smoking the legal high.
Video footage was posted on the internet of the 18-year-old singer and actress inhaling smoke from a bong - a filtration device - at a party held at her Los Angeles home last month, and since the controversy occurred sales of the drug have reportedly sky-rocketed.
According to gossip website TMZ, people are waking into shops and making a special request for "the stuff that Miley was smoking".
However, a number of state governments are now looking to ban the legal high - which is said to create a similar reaction to that of marijuana or LSD - as it is "so intense".
A smoke shop employee explained: "Salvia is one of those things that you only try once because it is so intense."
Meanwhile, Miley's father Billy Ray Cyrus recently took to twitter to express his disappointment at seeing his daughter inhale the legal high.
He wrote: "Sorry guys. I had no idea. Just saw this stuff for the first time myself. I'm so sad. There is so much beyond my control right now."
