Cannabis Laws in Shanghai

China’s drug laws apply uniformly throughout the country, including Shanghai. Under Chinese legislation, cannabis is classified as a narcotic drug and is strictly prohibited. Possession, use, cultivation, and distribution are all illegal activities. (Global Gold Analysis)

Activities that are illegal

The following activities involving cannabis are prohibited in Shanghai:

• Possessing marijuana

• Smoking or consuming cannabis

• Buying or selling weed

• Growing cannabis plants

• Importing cannabis products into China

• Transporting cannabis within the country

Chinese courts consider the amount of cannabis involved and the intent behind possession when determining punishment. (Is Weed Legal)

Trafficking marijuana may lead to:

• Nightclub inspections

• Customs screenings at airports

Risks for Foreign Visitors

Shanghai hosts one of the largest expatriate communities in Asia. However, foreigners must follow the same drug laws as Chinese citizens.

Possible consequences for foreigners

If a foreign national is caught with cannabis in Shanghai, they may face:

• Police detention

• Monetary fines

• Deportation

• Long-term bans from re-entering China

Even bringing cannabis products purchased legally abroad can lead to legal trouble when entering China.

• Cannabis dispensaries

• Marijuana cafés

• Weed festivals

• Public cannabis advertising

Strict law enforcement and strong social stigma prevent open cannabis culture from developing.

Social attitudes

Drug use is widely viewed negatively in Chinese society. Government anti-drug campaigns in schools, media, and public spaces emphasize the dangers of narcotics.

Public opinion generally supports strict drug laws and enforcement policies. (legalitylens.com)

As a result, marijuana use remains rare and hidden.

Although marijuana is illegal today, cannabis has a long history in China.

For thousands of years, hemp varieties of cannabis were cultivated for practical uses such as:

• Textile manufacturing

• Rope production

• Paper making

Industrial hemp is still produced in certain provinces under government supervision. However, these plants contain extremely low levels of THC and cannot legally be used as recreational drugs. (Alibaba)

China distinguishes strictly between industrial hemp and psychoactive cannabis.
