products, certain wooden products and other similar items. Similar restrictions exist in Canada, America and New Zealand. Border control in many countries in Asia and the Americas prioritises enforcing customs laws pertaining to narcotics. For instance, India and Malaysia are focusing resources on eliminating drug smuggling from Myanmar and Thailand respectively. The issue stems largely from the high output of dangerous and illegal drugs in the Golden Triangle as well as in regions further west such as Afghanistan. A similar problem exists east of the Pacific, and has resulted in countries such as Mexico and the United States tightening border control in response to the northward flow of illegal substances from regions such as Colombia. The Mexican Drug War and similar cartel activity in neighbouring areas has exacerbated the problem. In certain countries illegal importing, exporting, sale, or possession of drugs constitute capital offences and may result in a death sentence. A March 2018 report by Harm Reduction International says: "There are at least 33 countries and territories that prescribe the death penalty for drug offences in law. ... Between January 2015 and December 2017, at least 1,320 people are known to have been executed for drug-related offences - 718 in 2015; 325 in 2016; and 280 in 2017." A 2015 article by The Economist says that the laws of 32 countries provide for capital punishment for drug smuggling, but only in six countries – China, Iran, Saudi Arabia, Vietnam, Malaysia, and Singapore –are drug offenders known to be routinely executed. Additionally, Singapore, Malaysia, and Indonesia impose mandatory death sentences on individuals caught smuggling restricted substances across their borders. For example, Muhammad Ridzuan Ali was executed in Singapore on 19 May 2017 for drug trafficking. According to a 2011 article by the Lawyers Collective, an NGO in India, "32 countries impose capital punishment for offences involving narcotic drugs and psychotropic substances." South Korean law provides for capital punishment for drug offences, but South Korea has a de facto moratorium on capital punishment as there have been no executions since 1997, even though there are still people on death row and new death sentences continue to be handed down.

Such measures target a variety of issues, ranging from customs violations and trade in unlawful goods to the suppression of unauthorised migration or
