Sales of Salvia soar in wake of Miley Cyrus bong video

According to people who deal, legally, in salvia divinorum … sales have increased since Friday — in some cases up to 3 times the usual tally.

TMZ spoke with several head shops in the Los Angeles area and we’re told — not only have sales jumped — but many of the customers specifically asked for “the stuff Miley was smoking.” No … mentioning Miley did not get them a discount.

While Miley’s experimentation is generating curiosity in the hallucinogen — one smoke shop employee tells us, “Salvia is one of those things that you only try once because it is so intense.”
