Other widely used drugs included heroin and opioids. At the end of 2015, there were more than 2.3 million drug users in China, the report said. It also noted their young age – 60.6 per cent of the 2.3 million total were between 18 and 35 years old and 1.8 per cent were below 18. The remaining 37.6 per cent were 36 or older. According to information provided by the drug users, nearly 70 per cent of them were unemployed. Some 17.3 per cent were farmers, 4.7 per cent labourers, and 0.5 per cent students. The youth and farmers were the most active groups in drug trafficking, according to the report. Last year, 194,000 people were arrested for the offence, with 61.3 per cent aged below 35. Almost 80 per cent of the drug traffickers either were farmers or did not hold stable jobs. Other occupations included civil servants, students and labourers. Drug traffickers have also turned online to conduct their business. Some 15,000 of the cases uncovered last year involved communication over the internet. The authorities have intensified crackdowns on drug offenders, busting more than 5,800 drug trafficking gangs last year – an 18.1 per cent increase from 2014.
