OAKLAND -- Federal agents have seized hundreds of marijuana-laced candies, approximately 460 marijuana plants, one handgun, an unknown amount of money in a series of raids in the East Bay, authorities announced Thursday.

Drug Enforcement Administration Special Agent in Charge Javier F. Pena said multiple federal search and arrest warrants had been served in an investigation of Tainted Inc., an Oakland-based company that makes pot-laced candies sold in cannabis clubs in the Bay Area, Los Angeles, Seattle, Vancouver and Amsterdam in the Netherlands.

Among the products seized were marijuana-laced chocolate candy bars in multiple flavors, cookies, ice cream, peanut butter, jelly, BBQ sauce, chocolate syrup, flavored energy drinks, granola bars, moon pies, brownies, chocolate covered pretzels, and "rice krispy" treats.

"Tainting candy and other products with marijuana is not sweet, it is criminal," Pena said. "These items could have harmful effects on a user, especially the unsuspecting ones. Manufacturing, distributing, and possessing marijuana-laced products is in clear violation of federal law."

Pena said the investigation began about two years ago and led to Wednesday's searches of Tainted Inc.'s factory, marijuana growing facility, the El Sobrante home of owner Michael Martin, the residence of several other Tainted employees and cars identified as being used in Tainted's operations.

Agents also arrested Jessica Sanders, 30, of San Leandro; Michael Anderson, 42, of Oakland and Diallo McLinn, 35, also of Oakland on distribution charges.

Meanwhile, federal agents said Martin was being considered a federal fugitive at large.
