Home Minister Amit Shah at BIMSTEC conference on 'Combating Drug Trafficking' discussed about the reports concerning the menace and mentioned that it not only harms health but also poses threat to national security by being a source of income for terrorists. "Drugs business lead to health issues, breaking of families; it also poses serious threat to national security. Money circulating in this business is a source of income for terrorists, anti-national & anti-social elements," said Amit Shah. "As per UN's 'World Drug Report' around 4.5% of the people in the age group of 15-64 years, across the world, use drugs-over 27 Cr people across the world. It's a matter of concern that the figure is rising," he added further.
