Border
The region is the western region of Thailand's six-region system (regions of Thailand): the provinces of Tak, Kanchanaburi, Ratchaburi, Phetchaburi and Prachuap Khiri Khan. Its border on the map follows the OpenStreetMap boundaries of those provinces, clipped to the coast and the border with Myanmar, and simplified. Before October 2026 the page covered Kanchanaburi alone, and Bang Saphan, in Prachuap Khiri Khan, was filed under Southern Thailand; both changed when the region was redrawn on the five provinces.
The Tenasserim frontier
- The townships across the border are taken from OpenStreetMap as it stood on 20 October 2026: Bang Saphan District shares its western boundary with Bokpyin township (about 16 km) and Tanintharyi township (about 29 km) of Tanintharyi Region, and the Lenya river lies wholly in Bokpyin township, about 30 km from the district.
- The account of the 1890s is the evidence of one witness, the Deputy Commissioner of Mergui, who had it from a police officer. The Commission doubted his report of wild hemp and repeated his statement on cultivation. The growing that went on "on the Siamese side" was on the frontier the officer knew, the Pakchan, opposite Renong (Ranong), which is in Southern Thailand; no source read places it in the five western provinces.
- No source read records cannabis grown on the Burmese side being brought into Thailand. The one modern movement recorded runs the other way: in 2020 police at Mae Sot said cannabis being taken into Myanmar had come from north-eastern Thailand.
- Si Sawat District does not touch the border with Myanmar; its neighbours on the west are Sai Yok and Thong Pha Phum districts. The article does not call it a border district.
Sources
- Phrommatham and colleagues (2026), Wongwilairat and Punture (2024), Aksonsit and colleagues (2025) and Chaisan and colleagues (2025) are cited from their full texts. The Thairath and Matichon reports are in Thai; The Nation (2017) and the Chulalongkorn University release are also cited.
- The Hmong hemp sources concern Tak. No source found for Ratchaburi describes cannabis grown there. For Phetchaburi, Sanook News (2013, Kaeng Krachan) and Matichon (2018, Nong Ya Plong) report cannabis planted on cleared forest land.
- The Karen account from Si Sawat is an excerpt from a book on cannabis in Thailand, published by Bangkok Biz News in 2021; the book itself is not cited. The Mae Ramat report is cited from the copy on TeeNee.com, which credits Matichon.
Not used
- The Department of Medical Sciences' registered varieties named Tanaosri: the release gives no place of collection.
- A strain called Phetchaburi grown in Mae Hong Son is evidence of a name, not of a field in Phetchaburi.
- A 2022 report of a Ratchaburi enterprise printing cloth with a cannabis-leaf pattern concerns the leaf shape, not growing.
- Pounpunwong (2026), on hemp policy in Khiri Rat, is cited only from its abstract.
