A 52-year-old Portsmouth man is facing several drug charges as the result of an investigation that started in November. Authorities say Frank Rego was seen selling drugs from his home, which is within 300 feet of a school.  During a search of the house on East Main Road , they found bags of marijuana packaged for distribution and 19-thousand-dollars in cash. Fifty-four marijuana plants were also seized during a search of a second house connected to Rego.
