Real Cases: How Hong Kong Courts Sentenced Drug Offences

About these case summaries: the summaries below were prepared by this site based on our own reading and understanding of the judgments. They are not legal advice, have no legal effect, and must not be cited as authority. Cases are identified by neutral citation only, without party names; read the originals via the HKLII links. Sentences turn on the totality of each case's circumstances (drug type, quantity, role, plea); every figure below is what the cited judgment laid down or imposed, never a prediction for any other case. Our full verification process for case content — full-text reading of every judgment, corrigendum checks and independent human review — is set out in our methodology .
A hypothetical scenario
Imagine a young man asked by a "friend" to carry a bag across the border — "nothing much inside" — stopped, searched, and found with drugs. His family's first question: what do these cases usually mean in years? Hong Kong drug sentencing has a distinctive feature: the Court of Appeal sets quantity-based tariffs, making the framework comparatively transparent. Six Court of Appeal judgments show how the tariffs work — and what, beyond quantity, moved sentences in these cases.
The current tariffs: the 2025 unified guidelines (important notes)
In [2025] HKCA 234 (Court of Appeal, March 2025), the court laid down new unified sentencing guidelines covering heroin and cocaine (aligned for the first time) and revising the bands for methamphetamine (ICE), expressly replacing the long-standing earlier authorities. The framework runs from 2–5 years for up to 10 grammes of heroin/cocaine up to 27–30 years for 15–30 kilogrammes, with quantities above 30kg at the court's discretion (the judgment notes a practical ceiling of about 35 years); for ICE, from 3–7 years (up to 10g) to 27–30 years (15–30kg) ( judgment ).
Two disclosures this article must make. First, this is a 2025 judgment — more recent than the other cases in this series. Second, the defendant in that case later appealed against conviction to the Court of Final Appeal, which in [2026] HKCFA 3 quashed the conviction and ordered a retrial on a procedural ground unrelated to the sentencing guidelines (prosecutorial comment on the failure to testify). This article cites [2025] HKCA 234 solely as the guideline judgment — the Court of Appeal has continued to apply its guidelines in subsequent cases — and makes no comment on the individual concerned.
Tariffs for other drugs
- Ketamine: in [2008] HKCA 197 (Court of Appeal, 2008), the court set the ketamine trafficking bands: up to 50g at the court's discretion; 50–500g, 2–4 years; 500–1,000g, 4–8 years; above 1,000g, 8 years and up — also restating the ecstasy bands ( judgment ).
- Cannabis: in [2023] HKCA 103 (Court of Appeal, 2023), responding to average THC content rising from 1.73% (1995) to 19.2% (2021), the court revised the cannabis bands upward — for example, over 2,000g: 16–24 months; over 15,000g: 66–96 months; over 90,000g: 120 months and up — and adopted a 1:1 herbal-to-resin ratio ( judgment ).
- ICE (historical): in [2014] HKCA 279 (Court of Appeal, 2014), the then-governing ICE bands were set (up to 10g: 3–7 years; 10–70g: 7–11; 70–300g: 11–15; 300–600g: 15–20); the defendant, who trafficked 1,916g, had his sentence reduced from 25 years to 24 years 6 months. Superseded by the 2025 guidelines; included for historical context ( judgment ).
Pattern 1: quantity sets the starting point; role adjusts it
In [2020] HKCA 974 (Court of Appeal, 2020), a traveller arrived with 63.5g of cocaine (48.3g narcotic) internally concealed. The court explained that the quantity tariffs are calibrated for couriers of the lowest culpability: sentencing must assess the defendant's role in the chain before mitigation, and the appeal succeeded because the sequencing below had gone wrong (from a sentence of 5 years 8 months) ( judgment ). In these cases, "I was only carrying it" did not displace the tariff — but role moved sentences around it.
Pattern 2: partial self-consumption earns a limited discount
In [2011] HKCA 420 (Court of Appeal, 2011), the defendant trafficked 7.22g of ICE, part of it for his own use. The court confirmed a 10–25% discount from the starting point for the self-consumption portion — while noting the "latent risk" that such drugs could still reach others, and that funding one's own addiction is not mitigation. The total of 3 years 10 months stood ( judgment ).
The six cases at a glance
| Case | Court / year | Role in the framework |
|---|---|---|
| [2025] HKCA 234 | Court of Appeal, 2025 | Current unified heroin/cocaine/ICE guidelines (see notes above) |
| [2008] HKCA 197 | Court of Appeal, 2008 | Ketamine (and ecstasy) bands |
| [2023] HKCA 103 | Court of Appeal, 2023 | Cannabis bands (raised for higher THC) |
| [2014] HKCA 279 | Court of Appeal, 2014 | Former ICE bands (historical; superseded 2025) |
| [2020] HKCA 974 | Court of Appeal, 2020 | Courier role-adjustment principle |
| [2011] HKCA 420 | Court of Appeal, 2011 | 10–25% self-consumption discount |
Why Hong Kong drug sentences run so high
Deterrence recurs throughout these judgments: the quantity-tariff design makes sentence length track narcotic quantity above almost everything else, and personal circumstances (clean record, financial hardship) carried far less weight in these cases than in other offence types. Guilty pleas earn discounts, but the tariffs themselves did not move for sympathy — a message the Court of Appeal repeated across these decisions.
If you or a family member is arrested
- Rights on arrest (silence, representation): rights if arrested ; bail in drug cases is hard-fought — see the bail guide .
- Legal aid covers High Court / District Court criminal cases (10-working-day processing target).
- Plea, role disputes and mitigation are legal advice — with sentences measured in years, engage a criminal solicitor early.
