The owner of a Largo store is facing charges after police said an investigation revealed the store was selling synthetic marijuana.

William Zaharoff, 70, was arrested Thursday after a warrant was served at his business, Smokin' CDs on East Bay Drive.

According to police, the warrant was the culmination of a six-week investigation into the sale of synthetic marijuana at the business.

Zaharoff is facing two counts of sales of Schedule 1 substances and two counts of possession of Schedule 1 substances, all of which are felonies.

Police said additional substances were seized during the execution of the search warrant, and they will be tested for potential additional charges.

Zaharoff remains in the Pinellas County Jail on $30,000 bond.
