- Drug smuggling reached its highest point in South Korea, with arrests reaching 1,772 in 2O25 alone, 57.4% increase from the year before.
- Over 62% of South Korea’s drug offenders are young people. Drug dealers use the dark web and encrypted apps like Telegram to reach more buyers, of which the majority are youths.
- The South Korean authorities are getting ready to disband the Prosecutor’s Office by October 2O26. And experts say this move will hinder progress in the efforts to combat organized drug trafficking networks.
Drug trafficking cases have hit record highs in South Korea. In the past year alone, arrests jumped more than 50%.
A big part of this spike comes from the rise of online platforms, everything from the dark web and social media to encrypted chat apps.
Dealers and buyers connect faster and with less risk, and that’s made things a lot harder for authorities.
On top of all this, the main government agency leading the crackdown is about to be shut down in a few months. That timing has legal experts deeply worried.
Smuggling Cases Hit a Record High
The 2O25 White Paper on Drug Crimes released by the Supreme Prosecutor’s Office revealed a worrisome trend. Authorities arrested 23,403 drug offenders last year, a 381 increase from the number of 23,022 arrests the year before.
This trend is within the scope of the overall escalation of cross-border drug trafficking. In 2O24, there were 1,126 cases of drug trafficking, while in 2O25 this number rose to 1,772 cases. Drug manufacturing cases also rose by more than 31%, though they remain rare.
Foreigners are playing a bigger role in this surge. They constituted 37.1% of all smugglers. The number of foreign drug offenders that authorities arrested in Korea amounted to 3,298. It is also a record figure. Thailand was the top source country for seized drug shipments, followed by the United States, Canada, and Germany.
The types of drugs seized have also changed. Last year, Ketamine seizures shot up, almost tripling to hit 140.6 kilograms. Ecstasy wasn’t far behind, with a 30.6% jump compared to the year before, reaching 44 kilograms. Also, Meth seizure hit a new high, with a 25.2% spike, a total of 376.6 kilograms seized.
Dark Web and Telegram Reshape the Market
Investigators say the internet has become the central hub for South Korea’s drug trade.
The white paper points to increased use of the dark web and encrypted messaging platforms such as Telegram. These platforms are where dealers advertise drugs, communicate with buyers, and arrange payments without meeting face to face. Younger people, who are generally more comfortable using digital platforms, now make up most drug offenders.
People in their teens through their 30s accounted for 62.3% of all drug offenders in 2O25. Those in their 30s became the largest age group for the first time, narrowly overtaking offenders in their 20s. Teen offenders also increased compared with the previous year.
The South Korean government has already expanded online monitoring in response. Authorities use an Electronic Drug Monitoring System that scans the dark web and social media for drug advertisements. It uses keyword searches and AI-powered image recognition to find these drug ads. Specialized investigation teams also conduct undercover online operations and request the removal of illegal posts.
Similar enforcement efforts are underway globally. Australian police have charged a suspect in an $80 million dark web drug ring.
Academic researchers have also warned that Telegram’s encryption, anonymous accounts, and rapid account turnover create an “investigative asymmetry” that makes identifying suspects more difficult, particularly in cases involving younger offenders.
Justice Reforms Raise Enforcement Concerns
The report comes amid plans to reform the country’s criminal justice system. The National Assembly of South Korea last year voted to dissolve the Supreme Prosecutors’ Office. Under the new plan, the Prosecutors’ Office will be dissolved from October 2O26.
That ends its 78-year run, ending prosecutors’ direct authority over drug investigations and their ability to command special judicial police officers during operations. Come October, its powers will be split between two new agencies.
Presently, prosecutors play an important role in drug investigations. Experts have voiced worries that abolishing the office could have negative consequences on investigations that depend on real-time cooperation between customs officials, prosecutors, and police officers.
One example is controlled delivery. When customs officers catch a courier at the airport, a prosecutor steps in fast. They direct the investigation and push for warrants against the wider network. This quick teamwork makes “controlled delivery” possible.
That is when officers allow a drug shipment to keep moving, so they can catch both the buyer and the seller at once. Without it, officers often catch only the courier, and the real network gets away.
But once prosecutors lose their power, police will run these cases alone. Current law says a prosecutor must request controlled delivery before it can happen. Lawmakers need to rewrite that rule before October, or the tactic could stop working altogether. Building up new skills inside a fresh agency takes time.
International Cooperation Remains Critical
South Korea has spent years building partnerships with foreign law enforcement agencies to track drug shipments back to overseas suppliers.
Currently, prosecutors work through international cooperation programs that connect overseas manufacturing groups with domestic distribution networks. This helps investigators target entire criminal organizations instead of individual couriers.
One program tracks drug networks back to where they start. Another combines prosecutors and customs officers to study cases together. Both have helped in cutting off drug supplies before they reach Korean ports.
Officials fear those relationships could weaken if responsibilities shift before replacement systems are fully established. That will make tracking suppliers overseas much harder.
A senior prosecutor who worked on drug cases said it plainly. Nobody has settled the basic questions yet, like who will investigate what. That has created real confusion. He warned that as drug sales spread through social media and the dark web, any break in the current system could let the problem grow even faster.
What Happens Next
Lawmakers still have work to do before October. They need to update the law on controlled delivery. They need to figure out how the new agency will handle cases that cross borders. And they need to train police and other officers before prosecutors step back.
For now, the arrest numbers keep climbing. And the clock on Korea’s biggest law enforcement change in decades keeps ticking down.
