SAN ANTONIO -

A tip from a parent helped San Antonio police uncover what they believe is a synthetic marijuana operation worth half a million dollars at a northwest side gas station.

The woman called police Tuesday night after she found her son smoking a substance he said he bought from the Phillips 66 gas station on Loop 410 at Evers Road.

San Antonio police investigated and found what they call synthetic marijuana at the station worth an estimated $500,000.

Officers found small bags of substances marketed as potpourri that were selling for $30 to $40, and 500,000 empty bags on top of the full bags that were ready to be sold.

No arrests have been announced in connection with the case, and police said the synthetic marijuana will be tested to determine if there are any banned substances in the product.

"It's called the 'legal high,' but it's not the legal high, and we're going to combat this," said Sgt. Dave Berrigan, with the San Antonio Police Department's Narcotics Division.

According to SAPD investigators, the chemists who make synthetic marijuana frequently change the chemical makeup to avoid using chemicals that are banned.

Even though police consider the substance to be dangerous, investigators said the product is not necessarily an illegal drug.

"This is rampant throughout San Antonio, and we just want to get it out so we can put a stop to this because the people buying are juveniles, and it can actually kill you," Berrigan said.
