1. The Absolute Forbidden List
China maintains a strictly defined list of narcotics and psychotropic substances. Carrying, using, or trading these will lead to immediate detention or harsher penalties.
Narcotics: Opium, Heroin, Morphine, Cocaine, and Cannabis (Marijuana) in all forms.
Synthetic Drugs: Methamphetamine (Ice), Ketamine, and MDMA (Ecstasy).
CBD Products: Even if legal in the U.S. or Europe, CBD oil and hemp-derived products are strictly illegal and will be detected by customs sensors.
2. The "Foreign Ingestion" Trap
Under the newly revised Law on Penalties for Administration of Public Security (2026), Chinese authorities have the legal power to conduct random drug tests (hair or urine) on foreign nationals in nightclubs, bars, or at the border.
Jurisdiction: If you test positive for drugs, Chinese law can prosecute you regardless of where or when you consumed the substance.
Consequence: Testing positive is treated as "Administrative Drug Use," leading to 10–15 days of detention and mandatory Deportation (usually with a 5-year re-entry ban).
3. When "Zero Tolerance" Becomes "Capital Punishment"
China is one of the few nations that applies the Death Penalty to non-violent drug offenses. The following thresholds often trigger the highest sentencing:
50 grams or more of Heroin or Methamphetamine.
1 kilogram or more of Opium.
Large-scale manufacturing or organized trafficking (regardless of citizenship).
4. Medication Compliance
If you are carrying prescription drugs for ADHD (e.g., Adderall, Ritalin), chronic pain (e.g., Codeine), or anxiety, you must:
Keep the medicine in its original pharmacy packaging.
Carry a translated copy of your doctor's prescription.
Ensure the quantity does not exceed a 30-day supply (or the duration of your visa).

Actionable Advice from [www.hirelawfirm.com]
Clear Your System: If you have recently consumed legal cannabis in Canada or the US, we recommend waiting at least 90 days before traveling to China to ensure hair follicles are clear of metabolites.
Sanitize Your Luggage: Traces of drug residue on old bags can trigger high-sensitivity "swab tests" at Shenzhen/Hong Kong customs.
Never Accept Parcels: Do not carry items for strangers. Under Chinese law, "Willful Blindness" (deliberately not asking what is in a package) is not a defense against trafficking charges.
