Drug Trafficking Laws in Nepal 2026 — Penalty Guide

Cannabis up to 5 g, charas up to 2 g, heroin / cocaine up to 2 g fall on the consumption side. Above thresholds enters the trafficking ladder under Sec 14.

Discretionary. Effectively non-bailable for offences carrying >3 years (most trafficking matters). Bail more readily granted for consumption and small-cannabis matters.

Section 3 of the Act lists the prohibited substances — cannabis (ganja, charas, hashish), opium poppy, coca and cocaine, morphine, heroin, amphetamine-type stimulants and psychotropic substances. The schedule covers naturally derived and synthetic narcotics. Government notification can add new substances. Section 4 prohibits all activities — cultivation, production, sale, purchase, storage, possession, transport, import, export and consumption — with respect to scheduled drugs.

Cannabis consumption under the personal-use threshold (up to 5 g) attracts up to 1 month imprisonment or NPR 2,000 fine. Above the threshold the case enters the trafficking ladder. The line between consumption and trafficking can be drawn or rebutted by intent evidence — scales, packaging, cash, message records — and a skilled defence can sometimes establish personal use at quantities above the strict threshold. For routine small-cannabis consumption matters, the case is heard at the District Court.

Heroin and cocaine sit in the hard-drug penalty ladder under Section 14. Up to 25 g attracts 5-10 years' imprisonment and NPR 5,000-25,000. 25 g to 100 g attracts 10-15 years and NPR 70,000-200,000. Over 100 g attracts 15 years to life and NPR 500,000-2,500,000. Bail is effectively non-bailable. Foreign nationals face the same regime with post-sentence deportation. CIB / NCB lead investigation; the case is heard at a court constituted by Government notification under Section 21A.

The Narcotics Control Bureau is the dedicated anti-narcotic enforcement arm of Nepal Police, headed by a DIG. It was originally formed as the Narcotic Drugs Control Law Implementation Unit on 24 February 1993 and upgraded to NCB on 14 August 2012 by Council of Ministers decision. The Bureau operates 15 branch offices, including at Tribhuvan International Airport and nine Terai border checkpoints, with the headquarters at Singha Durbar. Email: ncb@nepalpolice.gov.np.

Intent to traffic is inferred from physical evidence at the seizure point — quantity above the consumption threshold, packaging in retail-sized portions or smuggling concealment, scales and weighing equipment, cash bundles, multiple mobile SIMs, ledgers / accounts, and communications records of transactions. Witness statements from purchasers or co-accused (where they cooperate with the prosecution) are also used. The defence can rebut intent by showing the quantity is consistent with personal use over a period, the buyer / supplier relationships do not exist, and the surrounding paraphernalia is consistent with use.

Yes. The Narcotic Drugs Act 2033 applies extraterritorially to Nepali citizens abroad and to all persons within Nepal regardless of nationality. Foreign nationals face identical penalties to Nepali citizens, with the additional consequence of post-sentence deportation under the Immigration Act 2049. Most foreign embassies actively monitor and assist their nationals in Nepal narcotic cases — consular access during custody is permitted under international convention. Bail conditions for foreign nationals are tighter because flight risk is treated as higher.

A person convicted of a narcotic offence and subsequently convicted again faces an additional up to 5 years' imprisonment plus NPR 100,000 fine on top of the base penalty for the subsequent offence. The enhancement applies independently of the underlying drug-type and quantity ladder. Multiple historical convictions can stack further. The prosecutor pleads the prior conviction in the charge; the defence must address the prior at sentencing to seek mitigation, particularly if the prior was for a different drug or quantity.

Under the Narcotic Drugs Act 2033 the NCB can hold a suspect in police custody for up to 3 months during investigation, with extensions one month at a time on Court authorisation. The Criminal Procedure Code 2074 requires the arrested person to be produced before a judicial authority within 24 hours of arrest. During custody the suspect has the right to counsel, the right to consular access (for foreign nationals), and the right to medical attention. Statements without counsel are challengeable at trial.

No. Despite cultural and historical use of cannabis in Nepal, all forms — recreational, medical and industrial — are prohibited under the Narcotic Drugs Act 2033 absent specific government permission. There is no licensed medical cannabis programme as of 2026. Industrial hemp cultivation has been discussed in policy circles but no statutory regime has been implemented. Reform discussions appear periodically in the Federal Parliament but no Bill has been passed. Until a new statute is enacted, the present prohibition holds.

The Department of Customs is the primary intercept agency at international border crossings and airports. Customs officers, often working with NCB on co-located operations at Tribhuvan International Airport and the Terai border checkpoints, screen cargo, passengers and parcels for narcotic contraband. Upon detection, Customs hands the case to NCB for criminal investigation; Customs separately pursues smuggling penalties under the Customs Act 2064. Joint operations are routine at TIA and the India-Nepal border.

The seized substance is sealed in evidence bags at the scene, transported with a chain-of-custody document, weighed at the lab on a calibrated scale, and tested for purity and chemical composition. The gross weight (with packaging) and net weight (substance alone) are recorded separately — the trafficking-ladder thresholds apply to net weight. Multiple seizures from a single operation are typically aggregated. Defence challenges to the seizure quantity focus on chain-of-custody breaks, calibration records, and whether the tested substance matches the substance charged.

Section 4 read with Section 14 of the Act extends to financing or facilitating any prohibited drug activity — providing money, transport, premises, communication, or other support to a cultivator, manufacturer, trafficker, importer or seller. The financier / facilitator faces the same penalty tier as the principal offender based on the underlying drug type and quantity. This is the basis on which charging extends from the courier or seller to the network behind them. The defence work involves disentangling true financing from incidental support.

The Narcotic Drugs Act 2033 contemplates rehabilitation as a sentencing consideration for consumption-tier offences, particularly for young or first-time offenders. The court can direct the convicted person to a recognised rehabilitation centre for the duration of the sentence or a portion of it. Rehabilitation pathways are limited in Nepal — government-run centres are few and most operate privately or under NGO oversight. For trafficking-tier offences rehabilitation is not a substitute for the prison sentence; it can only be a parallel pathway.

The Ministry of Home Affairs (MoHA) is the policy ministry for narcotic control. MoHA frames national drug-control policy, coordinates with the international UNODC framework on transit-country obligations, oversees the NCB through Nepal Police, and proposes amendments to the Act when needed. MoHA also handles inter-country requests for mutual legal assistance and extradition in narcotic cases. Reform discussions for the Act 2033 — including penalty recalibration and rehabilitation expansion — have been on MoHA's policy agenda but no statutory amendment has been enacted in recent years.

The Narcotic Drugs Act 2033 does not set an explicit limitation period for serious narcotic offences. Consistent with the treatment of grave offences in Nepal's criminal jurisprudence, narcotic trafficking — particularly the over-100 g hard-drug tier with potential life imprisonment — is treated as having no effective limitation, allowing prosecution whenever the offence comes to light. For minor consumption matters the general limitation framework under the Criminal Procedure Code 2074 applies; consult counsel before treating any narcotic complaint as time-barred.

Transit through Nepal does not exempt a person from the Act — any prohibited substance carried into or through Nepal triggers the offence regardless of the final destination. Detention by Customs or NCB at TIA or a border crossing leads to formal arrest, statement recording, and case filing at the appropriate court. Foreign nationals should request consular access immediately, retain a Nepal lawyer, and avoid statements without counsel. Transit defences (no intent to enter Nepal, accidental layover) are factual and case-specific.

Immediately on arrest or NCB contact — narcotic charges escalate quickly because of the custody timeline and bail position. Also at any house, vehicle or premises search; before any NCB statement; during the chain-of-custody and laboratory-testing stage where defence engagement can affect the charge; at the bail hearing; throughout the trial; and on appeal to the High Court within the 35-day window. A lawyer also handles consular and family communication during custody, which can be the difference between a manageable case and an isolated suspect.
