Slight drug abuse has appeared in the country. Free trade with neighboring India and the refugees make Bhutan vulnerable to drug trafficking. Bhutan is close to certain areas in Nepal and North-East India where intravenous drug use is high. Because of this, Bhutan has had an increase in intravenous drug use. Marijuana, which grows as a shrub in Bhutan, was only used to feed pigs before the introduction of television. Hundreds have now been arrested for using marijuana. Use of amphetamines and benzodiazepines smuggled from India is rising in Thimpu and in the Southern Bhutan. Drug trafficking and production of opium, cannabis and other drugs is not a large problem in the country.
