"It's a terrible feeling, it’s feels like being in a game world."This is how a 14-year-old boy described what he felt like after smoking a "herbal blend" purchased over the counter in Pretoria. The teen was interviewed by Jacaranda FM’s Martin Bester on Tuesday. Two weeks ago, 14 young adults and teenagers from Pretoria were hospitalised after smoking the substance known as herbal blend, puff or blazing."Your mind feels hazy," the teen, accompanied by his mother, told Bester.The boy said it felt like he had no control over himself. "You feel hopeless [moedeloos], like you can’t do anything for yourself," the boy said. "Your body just moves by itself. Your mind has no control over your body."Bester battled to elicit responses from the withdrawn, curt teenager. He admitted he had felt regret upon watching a video of himself under the influence of the mystery substance. "I shouldn’t have smoked it," he said. Last month, three teenagers from Pretoria West, still in their school uniform, had to be rushed to hospital after smoking the unknown substance.

The substance was similar to marijuana, Selepe said."SAPS have urgently sent the substance to a SAPS forensic lab for testing. Police have opened an enquiry, waiting for forensic results." Police have also urged parents to remove suspicious packages that their children may have in their possession and report it to the police.Police have not opened a case yet and have lodged an inquiry into the substance instead."If it is found that the substance is a drug, then all those who are selling it will be arrested and charged for dealing in drugs," she said.Selepe said the substance was either mixed with a cigarette or rolled like a cigarette and smoked plain.ALSO READ: Herbal blend, puff, blazing: Pretoria school children hospitalised after smoking unknown 'drug'
