Cannabis in South Korea
Cannabis in South Korea is illegal for recreational use. In November 2018, the country's Narcotics Control Act was amended and use of medical cannabis became legal, making South Korea the first country in East Asia to legalize medical cannabis.
While cannabis use has risen in South Korea since the 1970s, it remains far less popular than synthetic drugs such as methamphetamine; of 11,916 people arrested for drug crimes in 2015, only 1/100 were for cannabis-based drugs.
Cannabis was an important crop in ancient Korea, believed to be introduced to the region via the Silk Road from South Asia, with samples of hempen fabric discovered dating back as early as 3000 BCE. The traditional sambe cloth, an ivory colored fabric, is made from hemp. In addition to its use as fabric, the hemp seed was thought to have medicinal qualities such as a laxative.
Following the Rhee Syngman administration's 1957 Narcotics Act, "Indian Marijuana", along with poppies, opium, and cocaine, was labelled a forbidden narcotic. There is speculation that this act was heavily encouraged by the U.S. Treasury Department's Federal Bureau of Narcotic's first commander Harry Anslinger, who had long been advocating for its prohibition. Importantly, the 1957 act only outlawed Indian-grown marijuana, allowing the Korean market of cannabis growth to flourish.
In the 1960’s Korean cannabis usage rose dramatically with the influence of hippie culture diffusing outwards from U.S. army bases in Korea. Using the "happy smoke" started to symbolize rebelliousness, and many popular singers of the time began smoking the herb.
In the 1970s, amid its associations with insurgent youth culture abroad, cannabis was banned in all forms under the Cannabis Control Act of 1976, which later merged with the Narcotics Control Act in 2000. The across-the-board ban on cannabis remained unchanged. 
In January 2018, Rep. Shin Chang-Hyun, a member of the National Assembly of South Korea, proposed a bill that would revise the Narcotics Control Act and allow individuals with specific medical conditions to use cannabis with the approval from the Ministry of Food and Drug Safety.
The proposed revision overcame a major obstacle later in July when it won the support of the ministry, which said at the time it would permit Epidiolex, Marinol and Sativex for conditions including epilepsy, symptoms of HIV/AIDS and cancer-related treatments.
Use of medical cannabis is legal with the approval from the Ministry of Food and Drug Safety. Currently, the ministry only allows Epidiolex, Marinol and Sativex. The plant itself alongside its natural derivatives and extract, despite legal under the law, has yet to be approved.
Prior to obtaining the drug, patients are required to apply to the Korea Orphan Drug Center, a government body facilitating patient access to rare medicines, after receiving a doctor’s prescription. Approval will be granted on a case-by-case basis.
The import of the drug is set to begin in early 2019, according to the ministry.
South Korean authorities have repeatedly warned their citizens that they are subject to their country’s criminal code no matter where they are in the world and advised them to refrain from using cannabis abroad.
Cannabis has been a source of fabric for Korea since ancient times, and as recently as the 1930s hemp was grown in every province of Korea, particularly in the south where it grew best. In the late 1950s, 9,000 hectares of hemp were cultivated in South Korea.
A Korea Times article of 2014 noted that despite risks of a prison sentence of up to five years or a fine of up to 50 million won ($48,000), cannabis could be easily bought in South Korea by contacting dealers on the Internet. Its journalist noted that according to dealers, cannabis sold for US$30–50 per gram.
In popular culture
In the pursuit of scapegoats to increase the popularity of his 1976 Cannabis Control Act, South Korean President Park Chung-hee turned his gaze inwards, towards pop entertainers performing at U.S. Army bases, a hotbed of marijuana usage. In the winter of 1975, Park Chung-hee led a government crackdown on marijuana usage, resulting in the arrest of over 50 well known South Korean entertainers. Among them was the rock singer Shin Jung-hyeon, defamed in the media following his arrest as the "daemacho ringleader." He was imprisoned for four months following his arrest.
A number of high profile K-pop artists have been prosecuted for the recreational use of marijuana. Notable entertainers arrested for cannabis usage include Kim Kye-hoon, better known by his rap name, Crown J, singer-songwriter Psy, and Big Bang's T.O.P. The celebrities received a variety of sentences, with prison time ranging from 25 days to 10 months.
Along with legal action, societal backlash against the disgraced stars is often swift and serious. After T.O.P. was charged for possession and usage of marijuana, his record label YG Entertainment became widely referred to as Yak Guk (Hangul: 약국) Entertainment, which translates to "the drugstore." With an average of 40 months following a drug related scandal for a Korean entertainer to return to the stage, K-pop artists apprehended for using cannabis often have a difficult time regaining their lost stardom.
