Eleven Indiana teens ingested drug-infused gummy bears Thursday, a move that landed them in a hospital, police said.

LaPorte County police said the gummy bears were larger than the well-known versions of the sweet candy and were believed to have contained tetrahydrocannibol, also known as THC, the Times of Northwest Indiana reported. THC is an active ingredient found in marijuana.

The nine 18-year-olds and two 19-year-olds -- including six males and five females -- told police they ate half a candy each, which resulted in blurred vision, rapid heartbeats, hallucinations and pain in their legs, LaPorte County Police Capt. Michael Kellems said.

Two of the patients had high levels of THC in their systems, police said. Kellems said the remaining portions of the candy will be tested to determine their content.

The teens were from Fishers, Indiana and were believed to be staying in the same residence, police said. The LaPorte County Drug Task Force is pursuing leads in the case, the Times reported.
