Weed is not legal in Hong Kong. Cannabis in every form, including the plant, resin, extracts, edibles, vape cartridges, and oils, is listed as a dangerous drug under the Dangerous Drugs Ordinance (Cap. 134), alongside heroin and cocaine. There is no recreational allowance, no medical exception, and no minimum quantity that drops possession to a lesser offense. CBD was added to the same prohibition in 2023, so products that are sold openly in pharmacies elsewhere are criminal to carry here.
What the Law Covers
Cap. 134 controls cannabis itself and controls THC separately as a dangerous drug. Any product containing THC falls under the same prohibitions regardless of concentration, which sweeps in edibles, vape cartridges, oils, tinctures, and anything else derived from the plant. The law does not distinguish between recreational and personal use.
On February 1, 2023, Hong Kong classified cannabidiol (CBD) as a dangerous drug, making it fully illegal regardless of THC content.1U.S. Consulate General Hong Kong & Macau. Security Alert: Products Containing Cannabidiol (CBD) Criminalized in Hong Kong CBD oils, gummies, creams, and cosmetics that are sold legally in other countries carry the same penalties in Hong Kong as cannabis itself. A bottle of CBD oil that is legal where you bought it becomes a criminal offense the moment you land.
Penalties
Hong Kong’s drug penalties are among the harshest in the developed world. The specific punishment depends on the offense:
- Possession or consumption: up to 7 years in prison and a fine of HK$1,000,000 (roughly US$128,000). This applies to any amount, and covers smoking, inhaling, or ingesting cannabis in any form.2Hong Kong Police Force. Laws and Penalties
- Cultivation: up to 15 years in prison and a fine of HK$100,000 for growing any cannabis plant.
- Manufacturing: up to life imprisonment and a fine of HK$5,000,000 for producing cannabis products.
- Trafficking: up to life imprisonment and a fine of HK$5,000,000 for importing, exporting, supplying, or possessing cannabis for sale. Courts can infer trafficking intent from the quantity found on you, so you do not need to be caught selling to face this charge.
These are maximums, and judges have sentencing discretion. In practice, a tourist caught with a small amount for personal use would likely receive less than the statutory maximum, but a criminal conviction and prison time are realistic outcomes even for first-time offenders. Foreign citizenship is not treated as a mitigating factor. The penalties for CBD mirror those for cannabis.1U.S. Consulate General Hong Kong & Macau.

No Medical Exception
Hong Kong does not permit cannabis use for medical purposes under any circumstances. The government’s position is that the cannabis plant is not recognized as a medicine.3Narcotics Division, Security Bureau. Cannabis and the Law A prescription or medical cannabis card from another country provides no legal protection. There are no compassionate use exemptions and no patient registration system. This applies equally to pharmaceutical products like Sativex or Epidiolex that are approved in other jurisdictions. If you carry cannabis-derived medication into Hong Kong, you face the same penalties as a recreational user.
How Visitors Most Often Get Caught
Most arrests involving tourists trace back to assumptions carried from somewhere more permissive. Hong Kong Customs uses risk-assessment screening at entry points, focusing on passengers arriving from regions associated with trafficking, and combines intelligence analysis with physical luggage inspections.4Hong Kong Customs and Excise Department. Hong Kong Customs Detects Drug Trafficking Case Involving Incoming Passenger at Airport Cannabis discoveries in carry-on bags have led to arrests at Hong Kong International Airport as recently as 2026. Within the city, police can stop and search anyone they reasonably suspect of an offense, and the threshold is lower than many Western visitors expect.5Hong Kong Police Force. Stop and Search
The scenarios that catch people most often:
- Leftover products in luggage. A forgotten CBD gummy, a half-used vape cartridge, or a tube of CBD cream from a previous trip can trigger an arrest at customs. Empty your bags thoroughly before traveling.
- Online orders. Ordering CBD or cannabis products online for delivery to a Hong Kong address is an importation offense and can be charged as trafficking.
- Transit passengers. Hong Kong’s drug laws apply even if you are only connecting through the airport. Carry-on luggage is subject to inspection.
- Residual THC in your system. Because consumption is independently criminalized, testing positive could expose you to prosecution even if you consumed cannabis legally elsewhere before arriving. The offense is the consumption, not just possession of the substance.
- Food products. Items marketed abroad as hemp snacks or cannabis-infused drinks may contain traces of THC. Check ingredient labels before packing.
