The DTAM-trained worker rule: who qualifies and how to train staff
Thailand Cannabis Report · Reefers Club Co., Ltd. · Last checked 31 October 2026
Since 30 April 2026, a Thai cannabis shop needs more than a licence and a prescription for every sale. It needs a trained person behind the counter. The DTAM-trained worker rule is one of the four licence conditions in Ministerial Regulation No. 2, and one of the easiest to fail on an ordinary afternoon.
What the rule says
Ministerial Regulation No. 2 B.E. 2569 (2026) makes a DTAM-trained worker on duty a condition of every flower licence. Verified It sits alongside the other conditions: premises held by ownership or possessory right, flower stored separately and off the floor, and an odour and smoke removal system.
Trained worker, not prescriber
The trained worker is not a prescriber. Prescriptions come only from the seven prescribing groups. The worker's role is to run the shop within the rules: checking prescriptions and identification, keeping records and refusing sales that should not happen. See who can write a PT.33.
Who qualifies
A worker qualifies by completing DTAM's training for cannabis establishments and holding the certificate. Check DTAM's current schedule and format before you plan a hire.
Staffing the rule
- Cover every opening hour. One trained owner is not enough if the owner is not always there.
- Train more than one person. Sickness, leave and turnover should not leave the shop uncovered.
- Keep certificates on file at the premises, with the rota that shows who was on duty.
- Make the trained worker responsible for prescription checks, identification and the monthly PT.27 and PT.28 records. See PT.27 and PT.28 explained.
Why it matters at renewal
The trained worker is one of the checks every renewal has passed since 30 April 2026, and the Prime Minister directed on 22 October 2026 that renewals follow inspection. An inspector who finds the counter staffed by someone untrained has found a breach. See the licence renewal checklist.
