An underground pharmacy is now closed of business.
The woman accused of running it out of her San Juan home is behind bars.
San Juan Police confiscated hundreds of pharmaceuticals, many of which are controlled substances such as alprazolam, a drug popular among teens.
San Juan Police spent Friday morning sorting through hundreds of boxes of drugs-- seized during a search of Maria Garza TMs home.
Investigators say Garza would buy the drugs in Mexico and then sell them here in the United States.
When police learned of the possible underground operation, they sent in an undercover officer to make several purchases.
After successfully making the buy they were able to execute a search warrant.
Sgt. Rolando Garcia says the drug they are most concerned about is anti-anxiety medication-- Xanax.
"We're seeing a lot of that here with the younger crowd, Garcia said. A lot of the burglary suspects were apprehending are telling us they are barred out, taking these bars so they don't know what they are doing. We've had overdoes and deaths, resulting from these bars, it TMs dangerous and we are starting to see it more and more."
Garza is charged with one count of possession of controlled substances and two counts of manufacturing delivery of controlled substances.
San Juan police say Garza was selling the drugs at the Alamo flea market, but she wasn't there when the sheriff's department raided the market back in August.
