Narcotics Act Violation Lawyer | Understanding Charges by Offense Type
The Act on the Control of Narcotics, etc. (마약류관리법) punishes use, possession, sale, and manufacturing of narcotics as separate offenses, each carrying a different statutory sentencing range. Simple use or possession for personal consumption is treated far more leniently than sale, brokering, or manufacturing, which the law treats as trafficking-level conduct. Whether you self-reported before an investigation began, whether you cooperated, and whether you have an underlying addiction that a treatment and custody order could address are all factors that materially affect the outcome.

Narcotics Act Violation | How Use, Possession, Sale, and Manufacturing Are Punished Differently
The single most important question in a narcotics case is which category of conduct the prosecution alleges, because each carries its own sentencing floor and ceiling.
Use and Simple Possession
Using narcotics, or using or possessing Schedule Na and Da psychotropic drugs such as methamphetamine, without lawful authority is punishable by imprisonment for up to 10 years or a fine of up to KRW 100 million, while possessing narcotics such as heroin or cocaine carries imprisonment for at least one year, so penalties vary by the specific substance's classification (마약류관리에관한법률 제59조 제1항 제9호, 제60조 제1항). For many first-time users, the case may proceed as a summary indictment (약식기소) with a fine rather than a prison sentence, depending on the quantity involved and prior record.
Sale, Brokering, and Trafficking
Selling, brokering a sale, or delivering narcotics for profit is treated far more severely than personal use, with statutory minimums that can require a prison sentence even for a first offense (마약류관리에관한법률 제58조). If the conduct is found to be trafficking for export or import, the Act on the Punishment of Narcotics Trafficking, etc. (마약류불법거래방지에관한특례법) can apply, which allows for asset forfeiture and confiscation of proceeds in addition to imprisonment.
Manufacturing and Cultivation
Manufacturing narcotics, or cultivating plants such as cannabis or opium poppy without permission, is punished at a similarly severe level to trafficking because the law treats the creation of supply as a distinct threat (마약류관리에관한법률 제58조, 제59조). Even small-scale home cultivation cases are frequently prosecuted, and the actual or estimated yield of the crop is a key sentencing factor.
Narcotics Act Violation | Self-Reporting, Cooperation, and Treatment and Custody Orders
Because addiction is often part of the underlying reality in use and possession cases, Korean law and practice provide several routes toward a more treatment-oriented outcome rather than pure punishment.
Voluntary Self-Report Before Investigation
If a person voluntarily reports their own drug use before any investigation has started, the law allows the punishment to be reduced or exempted entirely (형법 제52조 제1항). Whether a report counts as a qualifying self-report depends on timing and how it was made, so this needs to be handled carefully before any statement is given to police.
Treatment and Custody Order as an Alternative to Prison
For defendants whose drug use stems from addiction, a request for a treatment and custody order (치료감호) can be raised, under which the person is committed to a treatment facility instead of, or alongside, a criminal sentence (치료감호 등에 관한 법률 제2조). Courts consider the risk of recidivism and the person's willingness to undergo treatment when deciding whether to grant this.
Suspended Sentence, Conditional Prosecution, and Diversion Programs
For first-time simple users with no aggravating history, prosecutors and courts have discretion to apply a suspended indictment (기소유예) conditioned on completing a drug rehabilitation education program, or to impose a suspended sentence with mandatory counseling. These outcomes are not guaranteed and depend on the quantity, substance type, and the defendant's cooperation during investigation.
Narcotics Act Violation | What Happens During Investigation: Urine and Hair Tests, Search and Seizure
Narcotics investigations frequently begin with a positive urine or hair follicle test, and the way evidence was collected can become a contested issue.
Urine and Hair Follicle Testing
Police typically request a urine sample and, for longer-term use patterns, a hair sample, since hair analysis can reveal drug use going back several months. A positive result is strong evidence but is not automatically conclusive, and the chain of custody and testing method can be examined.
Search, Seizure, and Warrant Requirements
Searches of a person's home, vehicle, or phone generally require a warrant except in narrowly defined emergency circumstances (형사소송법 제215조, 제216조). If evidence was obtained without a valid warrant or outside an exception, its admissibility can be challenged, which can materially change the strength of the prosecution's case.
Narcotics Act Violation | From Investigation to Resolution
We review the circumstances of your arrest or summons, including how any test results or search evidence were obtained, before you give any further statement to police.
We prepare you for interviews, including how to address prior use history and cooperation with any request for information about a supplier, which can affect sentencing recommendations.
Where applicable, we assess whether a voluntary self-report reduction still applies and whether requesting a treatment and custody order or rehabilitation program is a viable path.
The prosecutor decides whether to pursue a suspended indictment, summary indictment with a fine, or formal indictment for trial, depending on offense type and quantity.
If indicted, we present sentencing factors including addiction background, family circumstances, and treatment commitments to argue for the most favorable disposition available under the statutory range.
Narcotics Act Violation | How Fees Are Calculated
Set according to the offense category charged (use, possession, sale, or manufacturing), the number of charges, and whether the case is at the investigation stage or already indicted.
If agreed, this may be tied to specific outcomes such as a suspended indictment, non-custodial sentence, or successful treatment and custody order, rather than any promised result.
Covers costs such as expert review of test results, document fees, and travel to detention facilities or courts outside Seoul, billed separately from the retainer.
If asset forfeiture is sought by the prosecution under the trafficking-related statute, or if a separate treatment and custody hearing is required, this is generally billed as an additional scope of work.
※ Costs vary depending on case complexity and specific circumstances; exact fees will be provided during consultation. No specific outcome is guaranteed.
Narcotics Act Violation | Self-Check by Situation
1️⃣ If You Have Not Yet Been Contacted by Police
- Have you used or possessed a controlled substance and are unsure whether it has come to the attention of authorities?
- Are you considering a voluntary self-report and want to know if it would still qualify for reduced punishment?
- Do you have any physical evidence still in your possession that you are unsure how to handle?
2️⃣ If You Have Been Summoned or Arrested for Use or Possession
- Is this your first narcotics-related charge?
- Do you have a documented history of addiction or treatment that could support a treatment and custody request?
- Have you already given a statement to police, and if so, what did you say about how you obtained or used the substance?
3️⃣ If You Are Charged With Sale, Brokering, or Trafficking
- Did you personally profit from any transaction, or were you asked to deliver or hold items for someone else?
- Is there a risk that asset forfeiture proceedings could be brought against you under the trafficking-related statute?
- Was any of the evidence against you obtained through a search of your phone, home, or vehicle, and was a warrant used?
4️⃣ If You Are Facing a Manufacturing or Cultivation Charge
- What was the scale of the operation or number of plants involved?
- Can you demonstrate the substance was intended for personal use rather than distribution?
- Have you been asked to identify where you obtained equipment, seeds, or precursor materials?
