The Narcotics Control Act 2519 (1976) designates the Narcotics Control Board (NCB) with overall responsibility for prevention and suppression of illegal drug use in Thailand. The Office of the Narcotics Control Board (ONCB) is the body which implements any resolutions of the NCB and under provisions of this act and competent officials have the following authorities of stop, search and arrest if:

Note that the officials must have reasonable ground to believe that delaying any search in order to obtain a warrant would result in the escape of the suspects, or letting the substances in question being hidden, destroyed or in some other way being transformed.
2) To search any person or vehicle if there are reasonable grounds to suspect they are carrying or hiding illegal drugs
3) To enter and search premises without a warrant (having reasonable grounds for suspicion) and order a person or a group of people to undergo “on the spot” drug tests (under provisions of the fifth amendment of the Narcotics Act

The Act on Measures for the Suppression of Offenders in an Offence relating to Narcotics 2534 (1991) provides that two or more persons conspiring to commit an offence relating to narcotics shall be guilty of conspiracy and if the offence is subsequently committed, shall all be equally liable to the penalty imposed for such offences.
The above act provides for the forfeiture of all “instruments, equipment, conveyances, machineries or any other properties used in the commission of an offence relating to narcotics or used as accessories for producing the consequence of the commission of an offence relating to narcotics or possessed for use in the commission of an offence relating to narcotics,” irrespective of whether any person is convicted in relation to any such offences. Authorities may also ‘seize, restrain or confiscate the proceeds of drug trafficking’ in any case and additionally prosecute offences which took place outside the Kingdom if:
- The offender or any accomplice is a Thai national or has a place of residence in Thailand
- The offender is an alien and intends its consequence to occur within the Kingdom or the Thai Government is the injured person
- The offender is an alien and such act is an offence under the law of the State in the jurisdiction of which the offence is committed, if such offender has appeared in the Kingdom and has not been extradited under the law on extradition
