KATHMANDU, Sept 18: Despite the ban on the production and use of marijuana in South Asian countries such as Nepal and India, experts suggest that a significant portion of the global marijuana market is dominated by cannabis from this region and hashish derived from it. However, there have been surprising reports of marijuana produced in Western countries, such as the United States of America, Canada, and Europe, entering South Asian countries since 2076 BS. This contraband marijuana arrives in Nepal via air routes, concealed in parcels, and then reaches India through overland routes.
