Updated: Share Article AAA Two months ago, excise sleuths nabbed a 24-year-old from North Paravur with ganja and nitrosun tablets, a prescription drug used mainly to treat insomnia. It emerged that he has been into drugs from his teens when he used to inject it before gradually shifting to ganja and tablets. Then nearly a week ago, the Excise nabbed his 22-year-old friend and a fellow drug abuser with 53 grams of diazepam, another prescription drug used to treat anxiety. However, he had not yet made the shift and was still jabbing the drug, triggering concerns whether injections, which were considered an outdated mode, were making a comeback, especially in the North Paravur area. Excise sleuths have no idea how the youngsters are getting introduced to the far more dangerous mode of drug abuse.
