Hocking County Sheriff's deputies say a man was arrested on drug charges at a pharmacy, and that led them to a meth lab.
Brandon N. Smith, 31, was arrested in a parking lot of a CVS after purchasing pseudoephedrine for the alleged purpose of manufacturing meth.
Deputies said Smith has already been charged for running a mobile meth lab earlier this year and has five outstanding warrants against him from various agencies.
Sheriff Lanny North said he believes Smith is one of the largest meth manufactures and distributors in Hocking County.
Investigators said they went to Smith's residence on state Route 93 after he was in custody.
They discovered three active one-pot meth labs along with numerous bottles of liquid and crystal drain cleaner, Coleman fuel, propane, butane, ammonium nitrate, lithium batteries, coffee filters and coffee grinders.
Smith was charged with six felony drug counts.
His roommate, 26-year-old Jason D. McBride, was charged with three felony drug counts.
Both men are being held at the Southeastern Regional Jail.
