Many people only begin searching for legal information after receiving a police notice, being required to provide a urine sample, receiving a search warrant, or learning that a family member has been taken to a police station in connection with an amphetamine case. Common questions include:
“What category of narcotic is amphetamine in Taiwan?”
“How long is the sentence for possessing amphetamine?”
“What happens if I possess 20 grams?” “Will a first-timebe sent to rehabilitation?”
and “What should I do if accused of selling amphetamine?”
The legal consequences of an amphetamine case cannot be determined solely by the quantity seized or by statements such as
“It was only for personal use” or“I did not sell it.”
The substance involved, laboratory findings, pure net weight, purpose of possession, communications, financial transactions, packaging, consideration received, previous treatment records, and legality of police evidence-gathering procedures may all affect the charges and outcome.
※ This article, prepared by Chien Sheng International Law Firm, explains Taiwan’s legal classification of amphetamine, the 20-gram possession threshold, observation and rehabilitation, deferred prosecution with addiction treatment, the distinction between drug transfer and sale, and the criminal procedures involved in amphetamine cases.
It provides general legal information only. The outcome of any particular case must be assessed according to the evidence, laboratory reports, procedural history, and individual circumstances.
1. Are Amphetamine and Methamphetamine Category 2 Narcotics in Taiwan?
Under Taiwan’s Narcotics Hazard Prevention Act, amphetamine is classified as a Category 2 narcotic. Methamphetamine, commonly encountered in criminal investigations and sometimes referred to as “ice” or “crystal meth,” is also regulated as a Category 2 narcotic.
However, whether seized powder, crystals, tablets, or liquids actually contain a controlled substance must be established through legally obtained laboratory findings and other case evidence. Appearance, street names, and assumptions made at the scene are insufficient by themselves.
Article 2 defines narcotics as narcotic drugs and psychotropic substances, including their preparations, that possess addictive or abuse potential and pose risks to society.
Narcotics are divided into four categories according to their addictive potential, potential for abuse, and social harm:
■ Category 1: Heroin, morphine, opium, cocaine, and similar preparations.
■ Category 2: Poppy, coca, marijuana, amphetamine, pethidine, pentazocine, and similar preparations.
■ Category 3: Secobarbital, amobarbital, nalorphine, and similar preparations.
■ Category 4: Allobarbital, alprazolam, and similar preparations.
➡︎ The classification and listed substances are periodically reviewed by a committee formed by the Ministry of Justice and the Ministry of Health and Welfare. Adjustments are announced by the Executive Yuan and submitted to the Legislative Yuan for reference.
➡︎ The management of narcotic drugs and psychotropic substances required for medical and scientific purposes is governed by separate legislation.
The important point is that Category 2 narcotic offenses are not merely administrative violations. Possession, use, transfer, possession with intent to sell, sale, transportation, and manufacture are subject to different criminal provisions and potentially very different penalties.
2. Amphetamine Penalties: Possession, Use, Transfer, and Sale
The same package of amphetamine may give rise to different legal consequences depending on the conduct involved. Simple possession may constitute possession of a Category 2 narcotic. Consumption may constitute a separate offense of using a Category 2 narcotic. Giving the substance to another person without payment may constitute unlawful transfer, while transactions involving money or other consideration may lead to investigation for sale or possession with intent to sell.
The applicable offense is determined by the evidence, not simply by how the person describes the conduct. Investigators may examine pure net weight, packaging, scales, resealable bags, phone messages, call records, bank transfers, cash transactions, statements from alleged buyers, surveillance footage, and explanations concerning how the substance was acquired, possessed, or delivered.
3. Possession of Amphetamine: The 20-Gram Pure Net Weight Threshold
Article 11 provides the following penalties for possession:
■ Category 1 narcotics: Up to three years’ imprisonment, short-term imprisonment, or a fine of up to NT$300,000.
■ Category 2 narcotics: Up to two years’ imprisonment, short-term imprisonment, or a fine of up to NT$200,000.
■ Category 1 narcotics with a pure net weight of at least 10 grams: One to seven years’ imprisonment, with a possible additional fine of up to NT$1 million.
■ Category 2 narcotics with a pure net weight of at least 20 grams: Six months to five years’ imprisonment, with a possible additional fine of up to NT$700,000.
■ Category 3 narcotics with a pure net weight of at least 5 grams: Up to two years’ imprisonment, with a possible additional fine of up to NT$200,000.
■ Category 4 narcotics with a pure net weight of at least 5 grams: Up to one year’s imprisonment, with a possible additional fine of up to NT$100,000.
■ Equipment exclusively intended for manufacturing or using Category 1 or Category 2 narcotics: Up to one year’s imprisonment, short-term imprisonment, or a fine of up to NT$100,000.
One of the most frequently misunderstood figures in amphetamine cases is 20 grams. The statutory threshold refers to the pure net weight of the Category 2 narcotic, not the combined weight of packaging, containers, impurities, or the entire mixture.
Laboratory analysis may therefore be necessary to establish both the net weight and the concentration of the controlled substance.
For example, if a seized substance has a net weight of 30 grams and laboratory testing establishes a drug concentration of 50%, its pure net weight may be 15 grams.
Accordingly, the number of packages or a preliminary weight mentioned by police cannot independently establish whether the 20-gram threshold has been reached. The formal laboratory report is particularly important.
Possession of a Category 2 narcotic with a pure net weight of at least 20 grams carries a statutory penalty of six months to five years’ imprisonment, with a possible additional fine. This does not mean that every defendant will receive the same sentence. The circumstances of the offense and applicable sentencing factors must still be assessed individually.
4. Amphetamine Use: Criminal Liability and Addiction Treatment
Article 10 provides:
■ Use of a Category 1 narcotic: Six months to five years’ imprisonment.
■ Use of a Category 2 narcotic: Up to three years’ imprisonment.
Although amphetamine use carries criminal liability, Taiwan law also provides treatment-oriented procedures, including observation and rehabilitation, compulsory treatment, and deferred prosecution with addiction treatment.
These procedures reflect the fact that drug-use cases may involve addiction treatment and prevention of repeated drug use in addition to criminal punishment.
It is inaccurate to assume that a first-timemust always undergo observation and rehabilitation or that a second offense automatically results in prosecution.
The applicable procedure depends on the person’s previous observation or compulsory treatment history, the relevant dates, prosecutorial decisions, medical assessments, case evidence, and statutory requirements.
Completion of addiction treatment imposed as a condition of deferred prosecution is not legally identical to completion of observation and rehabilitation or compulsory treatment.
Determining how the statutory three-year period applies may require examination of previous case records and the complete procedural history.
Article 24 allows the prosecutor, in qualifying circumstances, to issue a conditional deferred prosecution disposition under the Code of Criminal Procedure instead of proceeding through the observation and rehabilitation or compulsory treatment procedures otherwise prescribed by law.
If the deferred prosecution disposition is revoked, the prosecutor must continue the investigation or institute prosecution.
Before imposing addiction treatment under the relevant provision of the Code of Criminal Procedure, the prosecutor must seek the opinion of a medical institution and may consult other relevant agencies or institutions when necessary.
The applicable treatment programs, eligibility requirements, implementation procedures, and standards for completion are governed by regulations prescribed by the Executive Yuan.
A willingness to undergo treatment does not automatically entitle a person to deferred prosecution. Medical assessment and the statutory procedure remain necessary.
A person granted deferred prosecution must also comply with the prescribed treatment, testing, reporting, urine sampling, and other conditions. Noncompliance may result in revocation and further investigation or prosecution.
5. Giving Amphetamine to Others Without Payment
Some people mistakenly believe that giving amphetamine to another person is not a serious offense if no money changes hands. However, a gratuitous transfer may still constitute the unlawful transfer of a Category 2 narcotic.
Article 8 provides the following penalties:
■ Transfer of a Category 1 narcotic: One to seven years’ imprisonment, with a possible additional fine of up to NT$1 million.
■ Transfer of a Category 2 narcotic: Six months to five years’ imprisonment, with a possible additional fine of up to NT$700,000.
■ Transfer of a Category 3 narcotic: Up to three years’ imprisonment, with a possible additional fine of up to NT$300,000.
■ Transfer of a Category 4 narcotic: Up to one year’s imprisonment, with a possible additional fine of up to NT$100,000.
Attempts are punishable. Where the quantity transferred reaches the prescribed threshold, the sentence may be increased by up to one-half.
Whether particular conduct constitutes transfer, joint use, purchasing on another person’s behalf, temporary custody, or a sale involving consideration must be determined from the actual circumstances and evidence.
The absence of a cash payment does not necessarily eliminate criminal liability.
6. Possession with Intent to Sell and Drug Trafficking
If investigators believe that a person possessed amphetamine for sale rather than personal use, the case may involve possession of a Category 2 narcotic with intent to sell.
Article 5 provides:
■ Possession of a Category 1 narcotic with intent to sell: Life imprisonment or imprisonment for at least 10 years, with a possible additional fine of up to NT$7 million.
■ Possession of a Category 2 narcotic with intent to sell: Imprisonment for at least five years, with a possible additional fine of up to NT$5 million.
■ Possession of a Category 3 narcotic with intent to sell: Three to ten years’ imprisonment, with a possible additional fine of up to NT$3 million.
■ Possession of a Category 4 narcotic, or equipment exclusively intended for manufacturing or using narcotics, with intent to sell: One to seven years’ imprisonment, with a possible additional fine of up to NT$1 million.
The statutory penalties are substantially higher where the conduct involves manufacturing, transporting, or selling narcotics.
Article 4 provides:
■ Manufacturing, transporting, or selling a Category 1 narcotic: Death or life imprisonment; life imprisonment may be accompanied by a fine of up to NT$30 million.
■ Manufacturing, transporting, or selling a Category 2 narcotic: Life imprisonment or imprisonment for at least 10 years, with a possible additional fine of up to NT$15 million.
■ Manufacturing, transporting, or selling a Category 3 narcotic: Imprisonment for at least seven years, with a possible additional fine of up to NT$10 million.
■ Manufacturing, transporting, or selling a Category 4 narcotic: Five to twelve years’ imprisonment, with a possible additional fine of up to NT$5 million.
■ Manufacturing, transporting, or selling equipment exclusively intended for manufacturing or using narcotics: One to seven years’ imprisonment, with a possible additional fine of up to NT$1.5 million.
Attempts are punishable.
A drug sale does not necessarily involve a face-to-face cash payment. Consideration may involve bank transfers, debt repayment, purchasing fees, cryptocurrency, exchanges of property, or other benefits.
Nevertheless, prosecutors must establish the relevant intent and transaction through evidence. Drug quantity, packaging, scales, communications, and financial records may be relevant, but their evidentiary value must be assessed in the context of the individual case.
7. Key Defense Issues in Amphetamine Trafficking Cases
Selling a Category 2 narcotic carries a statutory minimum sentence of 10 years’ imprisonment, making the distinction between sale, possession with intent to sell, transfer, and simple possession particularly important.
Important issues may include whether an actual buyer existed, whether consideration was exchanged, what the communications referred to, whether the seized substance can be linked to a particular transaction, whether financial transfers were drug-related, whether witness or co-defendant statements are supported by independent evidence, and whether police evidence-gathering procedures were lawful.
Some cases involve ambiguous conversations, unexplained payments, or allegations based primarily on a co-defendant’s statement. Others may involve surveillance, communications, delivery records, laboratory reports, and financial evidence that corroborate one another.
These differences may affect whether the prosecution can establish a completed sale, attempted sale, possession with intent to sell, or another offense.
A defense should not be based on fabricated explanations. Instead, the transaction background, communications, source of funds, acquisition of the substance, and actual role of each participant should be organized accurately and systematically.
In cases involving joint purchases, purchases on another person’s behalf, intermediaries, or alleged accomplices, the evidence must still establish the relevant intent, consideration, and division of roles.
8. Sentence Reduction for Disclosing Drug Sources or Confessing
Two common questions in drug cases are whether a confession automatically results in a reduced sentence and whether identifying an upstream supplier guarantees sentence reduction.
Neither result is automatic.
Article 17 provides three forms of potential sentencing relief:
1. A person who commits an offense under Articles 4–8, 10, or 11 and discloses the source of the narcotics, thereby leading to the apprehension of another principal offender or accomplice, shall receive a reduced sentence or exemption from punishment.
2. A person who commits an offense under Articles 4–8 and confesses during the investigation and at every stage of trial shall receive a reduced sentence.
3. A defendant who commits the transportation offense under Article 4 for the purpose of personal use, where the circumstances are minor, may receive a reduced sentence.
➡︎ The first provision requires more than merely naming a supplier. The disclosure must lead to the apprehension of another principal offender or accomplice.
Information that is insufficiently specific, produces no relevant result, or lacks the necessary causal connection with the apprehension may not satisfy the statutory requirements.
➡︎ The second provision applies to offenses under Articles 4–8, including manufacture, transportation, sale, possession with intent to sell, and transfer.
It requires a confession during the investigation and at every stage of trial. It does not apply to every narcotics offense merely because the defendant admits the conduct. Simple possession and use are not included in the confession-based reduction under Article 17, Paragraph 2.
Whether and to what extent to confess should therefore be considered carefully after reviewing the evidence and legal issues.
9. What Should You Do If Arrested for Amphetamine Use?
A person investigated for amphetamine use may face police questioning, prosecutorial examination, urine testing, an application for observation and rehabilitation, medical assessment, or consideration of deferred prosecution with addiction treatment.
The first priority is to understand the actual status of the case rather than relying on claims that a particular outcome is guaranteed.
Confirm how urine samples were collected, handled, submitted, and tested, and examine the relevant laboratory reports. Explain facts truthfully, but avoid presenting guesses or uncertain recollections as established facts.
Preserve lawful materials that may help establish what happened. Do not delete messages, destroy evidence, or coordinate statements with other people.
If the person wishes to receive treatment, it is important to understand that deferred prosecution with addiction treatment requires a statutory procedure and compliance with prescribed conditions.
A verbal expression of willingness to undergo treatment does not guarantee eligibility or approval.
If the case also involves possession, transfer, transportation, or sale—particularly where substantial quantities, packaging, financial transactions, seized phones, or alleged accomplices are involved—an attorney should review the laboratory findings, communications, financial records, search and seizure procedures, and statements as early as practicable.
10. How Can an Amphetamine Drug Crime Lawyer Help?
Amphetamine cases frequently turn on the identity of the substance, its weight, the purpose of possession, the existence of consideration, previous treatment records, and the legality of investigative procedures.
A lawyer’s role is to examine these issues against the evidence and applicable legal requirements rather than promise a particular outcome.
In drug-use cases, an attorney may help explain the differences between observation and rehabilitation, compulsory treatment, and deferred prosecution with addiction treatment. Legal assistance may also involve reviewing previous treatment records and identifying the appropriate procedural options.
In possession cases, the review may focus on the substance involved, net weight, pure net weight, laboratory methodology, seizure procedures, and evidence establishing possession.
Where sale or possession with intent to sell is alleged, the evidence may include communications, financial transactions, statements from alleged buyers, surveillance footage, seized substances, and corroborating materials.
The actual role and knowledge of each participant must be examined separately.
Chien Sheng International Law Firm handles various narcotics-related criminal matters, including drug use, possession, sale, transportation, manufacture, drug-impaired driving, and related money laundering or organized crime allegations.
When facing police questioning, prosecutorial investigation, search and seizure, observation and rehabilitation, addiction treatment assessment, or court proceedings, obtaining accurate information and organizing the evidence early can help protect the person’s procedural rights and support an appropriate case-specific response.
Identify the Charges and Evidence Before Deciding How to Respond
Amphetamine is classified as a Category 2 narcotic in Taiwan, but the penalties vary significantly according to the conduct involved.
Simple possession is treated differently from possession involving a pure net weight of at least 20 grams. Drug-use cases may involve observation and rehabilitation, compulsory treatment, or deferred prosecution with addiction treatment. Gratuitous delivery may constitute unlawful transfer, while transactions involving consideration or intent to sell may lead to substantially more serious charges.
Whether you, a family member, or a friend has received a summons, been asked to attend questioning, undergone a search, been required to provide a urine sample, or already been indicted, the case should not be assessed solely by labels such as “first-time offender,” “small quantity,” or “personal use.”
Laboratory findings, financial transactions, communications, procedural legality, previous treatment records, and the complete factual circumstances must all be considered.
Chien Sheng International Law Firm recommends seeking advice from a lawyer familiar with narcotics cases at an early stage so that each allegation, item of evidence, and procedural issue can receive appropriate legal examination.This reduces both medical risks and potential legal exposure.
