Thailand replaces its drug law with separate personal-use penalties

On 9 December 2021 Thailand replaced its long-running narcotics legislation with a single Code. Holding a category 1, 2 or 5 narcotic for consumption had a distinct penalty: up to two years in prison, a fine of up to 40,000 baht, or both. Consumption itself carried up to one year, a fine of up to 20,000 baht, or both, subject to the Code’s exceptions.^[1]

A separate route for personal possession

The Code distinguished possession for consumption from the other controlled activities involving narcotics. It also provided for a presumption of personal use when the amount did not exceed quantities to be set by the health minister. The statutory provision delegated the quantities; it did not itself supply a single cannabis gram limit.^[1]

The distinction mattered for cannabis, which still passed through a licensing system before the plant’s removal from the narcotics list in June 2022.^[2] Category 5 production, import, export, distribution and possession remained subject to the Code’s authorisation rules.^[1]

Treatment could take someone out of the offence

A person who sought treatment voluntarily before detection, met the prescribed conditions and obtained written certification of satisfactory completion could avoid guilt for the specified consumption or personal-use possession offence. Another provision allowed qualifying people detected by officials to be referred for voluntary treatment or screening.^[1]

For cases reaching court, the Code directed attention to helping the defendant stop using drugs through treatment over punishment. It allowed individual circumstances to matter, including age, health, family responsibilities and the reasons for using drugs.^[1] These were legal routes with conditions, not an automatic exemption for anyone holding a small quantity.

The end of the old Act, before the plant left the list

The Code replaced the Narcotics Act of 1979 and its amendments, alongside other drug-control and rehabilitation laws. Existing subordinate rules continued where compatible until replaced; provisions requiring new rules also had transitional conditions.^[1]

The next cannabis milestone came six months later. From 9 June 2022, the plant ceased to be listed as a narcotic while specified extracts remained controlled.^[2] The Thailand profile follows the later regulation of sales and medical access.
