Defending Drug Trafficking Cases: Quantity, Entrapment and Sentencing

In drug cases the quantity seized often fixes the sentencing bracket — but how that quantity is established, whether police entrapment was involved, and the defendant's role in a joint offence are where the real defence lies.

When family members first come for a consultation, they usually ask whether bail is possible or whether a suspended sentence can be obtained. In drug trafficking cases, however, the answers are often fixed during the investigation stage by two numbers: the quantity seized and the sentencing bracket it falls into. Article 347 of the Criminal Law provides that trafficking in not less than 1,000 grams of opium or 50 grams of heroin or methamphetamine carries fifteen years, life imprisonment or death; 10 to 50 grams carries not less than seven years. Once the quantity crosses a bracket, the room for defence narrows sharply. Defence in a drug case therefore does not begin in the courtroom — it begins with the first page of the weighing, sampling, appraisal and interview records.

1. Quantity: Purity Is Not Converted, but “Verified” Still Matters

The Criminal Law states that drug quantity is calculated on the amount verified by evidence and is not converted by purity. That means low purity usually cannot by itself move a case down a sentencing bracket, and families often conclude there is no hope. But the emphasis of the provision lies in the words “verified by evidence.” What actually needs scrutiny is whether the chain of seizure, detention, weighing, sampling, submission and custody is intact; whether the weighing deducted the tare, mixed different seizures, or counted packaging in the net weight; whether multiple packets were separately numbered and weighed; whether samples were representative; whether the laboratory and its analysts were qualified; and whether contamination or confusion was possible in the chain of custody. If any link breaks, that portion of the quantity may be impossible to establish. In cases where the death penalty may apply, a purity appraisal should also be conducted, and extremely low purity directly affects the assessment of whether death is appropriate.

2. Entrapment: Distinguishing “Opportunity” from “Inducement”

Drug cases rely heavily on informants, undercover contacts and controlled delivery. That is an investigative technique, and also an important point of defence. Under the Supreme People's Court's conference minutes on drug cases, police involvement is generally divided into three types. First, opportunity-providing: the defendant already intended to traffic and the informant merely supplied a chance to deal, which does not affect conviction. Second, intent-inducement: the defendant had no original intent and only formed it after repeated persuasion, inducement or pressure, which warrants a lighter sentence and generally rules out immediate execution. Third, quantity-inducement: the defendant intended to sell a small amount and the informant proposed or procured a larger quantity, and the increase should not be used as a sentencing basis. Defence counsel should compare call records, chat logs, money flows and the timeline of first contact against the transaction date to establish who raised the intent, who named the quantity and who prepared the funds. These details often decide the sentence, yet rarely appear in the narrative of the indictment.

3. Role: Purchasing Agent, Broker and Courier Are Treated Very Differently

The same act of “helping to get the goods” may fall under three different offences. Buying drugs on behalf of another person for personal use, with profit or a disguised markup, is treated as trafficking; buying without profit where the quantity is large is usually treated as illegal possession, with a very different sentencing range. The same is true of brokering: knowingly introducing a buyer or seller and bringing about the deal generally makes one an accomplice to trafficking, whereas merely contacting a seller at a drug user's request without profit is often not treated as a crime at all. For transport, the questions are knowledge, employment and whether the payment was obviously abnormal. A hired courier, a first offender, or someone tricked into participating with a minor role is generally not sentenced to immediate death. In the first lawyer meeting, then, the key questions are not “how much did you sell” but “who introduced you, how did the money move, whose goods were they, and what did you get out of it.”

4. Sentencing: Quantity Is a Threshold, Not the Whole Picture

Reaching the quantity threshold for the death penalty means the court “may” impose it, not that it “must.” The court also weighs purity, the defendant's culpability, voluntary surrender or truthful confession, meritorious service, repeat offending or drug-related recidivism, the defendant's position and role in a joint offence, and whether entrapment occurred. Voluntary surrender and meritorious service under Articles 67 and 68 are often the most valuable defence resources in drug cases, provided the facts and leads are genuine and verifiable — they cannot be invented. The leniency regime for admitting guilt and accepting punishment also applies, but admission presupposes clear facts and accurate characterisation; where quantity is doubtful or the role has been inflated, signing a statement prematurely can foreclose later defence options. That is why we usually advise families not to rush a defendant into “admitting everything” during the prosecution review stage.

5. What Families Can Do — and Must Never Do

What families can do: retain a lawyer promptly for the first meeting, confirm the suspected charge and the detention facility, deposit money and necessities according to the rules, and preserve original call logs and transfer records. What they must never do: contact co-defendants or witnesses to “align stories,” which may amount to obstructing testimony or harbouring an offender; ask the lawyer to carry case information or items during a meeting, which exposes counsel to professional risk and may be treated as collusion; or believe promises that an “inside connection” can secure release. Drug offences are a priority enforcement area, and such promises are almost always fraud. In a criminal case, what has value is the evidence and the timeline in the file — not any verbal assurance.

Conclusion

Defending a drug case is essentially meticulous work on two things: numbers and roles. The numbers set the starting point of sentence, the role sets where it lands, and procedure determines whether either conclusion can hold. The earlier counsel is involved, the better the chance of creating an effective record at the weighing, sampling and interrogation stages; the later, the more one is left arguing for leniency within fixed facts. If your family is facing such a situation, consult a criminal defence lawyer immediately after detention rather than on the eve of judgment.
