|title=Sri Lanka government survey estimates 16,000–18,000 chronic cannabis users
|summary=A Sri Lankan government survey estimated 3,500–5,800 opium dependents and 16,000–18,000 chronic cannabis users in the country. Based on a WHO conversion factor of 10 actual drug abusers for every one identified, the government estimated the total drug usage level could be as high as 1.5% of the population. The survey built on the 1978 Narcotics Advisory Board field investigation and represented the first attempt at national prevalence estimates. The figures would later be revised dramatically upward — by 2004, the NDDCB estimated 600,000 cannabis users and 45,000 heroin users, reflecting both actual growth in consumption and improved surveillance methods.
