NEWARK - Law enforcement officials say incidents involving synthetic drugs have declined since the state banned them last year. Attorney General Jeffrey Chiesa said calls to the poison control hotline about the stimulant known as bath salts have dropped by 66 percent.

Bath salts can cause agitation, psychosis and violence. New Jersey banned them in April 2011.

Calls about synthetic marijuana have dropped by 33 percent. Chiesa said state police have seen a 77 percent decline in fake marijuana submitted for testing since it was banned in February.

Synthetic marijuana, known as K2, can cause adverse reactions including hallucinations and paranoia. It was often sold as incense or potpourri. Both products were sold at convenience and other stores and online.
