WINDHAM, Conn. (AP) Willimantic police say they are dealing with a batch of tainted synthetic marijuana that has sent about a dozen people to the hospital since Monday.

Corporal Stanley Parizo, Jr., a police spokesman, says they began receiving calls at about 8 a.m. Monday of people exhibiting psychotic behavior after smoking the drug.

He says about a dozen had been sent to Windham Hospital as of Tuesday morning with extremely high blood pressures and temperature of up to 106 degrees.

He says police suspect the drug may have been laced with the hallucinogenic PCP and have sent samples to be tested. He says they are trying to track down the source of the pot.
