Thailand’s Office of the Narcotics Control Board (ONCB) has issued an official warning about the spread of a new synthetic drug known as 2C-B (2C-Bromine), commonly referred to as “pink cocaine”. Authorities say the substance is gaining attention among some nightlife and drug-using groups despite posing serious risks to both physical and mental health. Get today's headlines by email On 20 June, Ms Areepak Ngernbamrung, Deputy Secretary-General and spokesperson for the ONCB, said the agency is concerned about the growing presence of 2C-B. Although it is marketed as pink cocaine, she stressed that the drug is not cocaine but a synthetic psychoactive substance with potentially severe effects on users. According to the ONCB, 2C-B acts as both a stimulant and a hallucinogen, producing effects similar to LSD and ecstasy. Users may experience euphoria, unusual alertness, hallucinations, distorted perception, impaired judgement and reduced self-control. These effects can increase the likelihood of risky behaviour and may endanger both the user and others. The agency warned that prolonged use can damage the brain, leading to irritability and chronic hallucinations. Excessive consumption can be fatal. The ONCB also highlighted concerns raised during the recent International Symposium of Forensic Drug Testing Lab Directors, where experts reported that 2C-B and substances sold as pink cocaine are often distributed as complex drug mixtures. The drug is commonly sold in powder, tablet or capsule form and is increasingly mixed with other substances such as ketamine, cocaine or benzodiazepines. These mixtures are sometimes marketed as “Happy Water”, significantly increasing the risk of overdose and unpredictable reactions. Health risks associated with high doses of 2C-B or its use alongside other drugs include irregular heartbeat, high blood pressure, dangerously elevated body temperature, seizures and loss of consciousness. In severe cases, users may suffer sudden heart failure. The ONCB also warned that mixing the substance with the painkiller tramadol can cause respiratory depression, which may lead to immediate death because users often do not know the true composition or quantity of the substances they consume. The spokesperson noted that 2C-B is classified as a Category 1 narcotic under Thai law. Anyone who produces, imports, exports, distributes or possesses the substance without authorisation faces legal penalties. The ONCB urged the public, particularly young people, not to be misled by claims that pink cocaine is safe or harmless. The agency warned that synthetic drugs can have serious consequences for health, finances, future prospects and life itself. Daily News reported that authorities are expected to continue monitoring the spread of 2C-B and related synthetic drugs. Members of the public with information about illegal drug trafficking are encouraged to contact the ONCB hotline 1386, available 24 hours a day. Join the discussion? Already a member?
