Trafficking
The Golden Triangle (Southeast Asia), specifically Shan State, Myanmar, is the worlds leading producer of methamphetamine as production has shifted to Yaba and crystalline methamphetamine, including for export to the United States and across East and Southeast Asia and the Pacific.Concerning the accelerating synthetic drug production in the region, the Cantonese Chinese syndicate Sam Gor, also known as The Company, is understood to be the main international crime syndicate responsible for this shift. It is made up of members of five different triads. Sam Gor is primarily involved in drug trafficking, earning at least $8 billion per year. Sam Gor is alleged to control 40% of the Asia-Pacific methamphetamine market, while also trafficking heroin and ketamine. The organization is active in a variety of countries, including Myanmar, Thailand, New Zealand, Australia, Japan, China, and Taiwan. Sam Gor previously produced meth in Southern China and is now believed to manufacture mainly in the Golden Triangle, specifically Shan State, Myanmar, responsible for much of the massive surge of crystal meth in recent years. The group is understood to be headed by Tse Chi Lop, a gangster born in Guangzhou, China who also holds a Canadian passport. Liu Zhaohua was another individual involved in the production and trafficking of methamphetamine until his arrest in 2005. It was estimated over 18 tonnes of methamphetamine were produced under his watch. Legal status
The production, distribution, sale, and possession of methamphetamine is restricted or illegal in many jurisdictions.
