Eleven Indiana teenagers were hospitalised this week after eating cannabis-laced gummy bears.
LaPorte County police said the candy was believed to have contained tetrahydrocannibol, also known as THC - the active ingredient found in marijuana.
The teens, aged 18 and 19, reported hallucinations, blurred vision, racing pulses and pain in their legs, the police said on Facebook.

Police got involved after receiving a 911 call late on Thursday (local time) from one of the teens, who requested medical assistance.
The group of 11 were taken to hospital, where two of them were tested and found to have high levels of THC in their system.
Police do not know where the group got the candy from, but say they were larger than standard gummy bears.
