ALBANY, N.Y. — Federal prosecutors say the owner of head shops in Maine and New York has pleaded guilty to five charges for possessing and intending to sell illegal synthetic drugs.

They say 33-year-old John Tebbetts of Floyd, N.Y., acknowledged having synthetic marijuana, marketed as “Legal Phunk,” and so-called “bath salts” that mimic illegal stimulants and were recently banned by federal law.
