The Lancaster County coroner says none of the overdoses were fatal.

Synthetic marijuana, often marketed as K2, is a hallucinogen that can raise a person's blood pressure and cause reduced blood supply to the heart. The National Institute on Drug Abuse says the chemical can cause kidney damage and seizures.

The district attorney's office says users of the drug can become erratic and aggressive.
