On October 25, 2019, Thailand’s Narcotics Control Committee issued a notification to clarify the definition of hemp, in order to rectify inconsistent definitions given in previous regulations on hemp. The notification took effect on October 26, 2019.

The October 25 notification defines hemp as Cannabis sativa L. subsp. sativa that contains tetrahydrocannabinol (THC) at the level of 1.0 percent or lower by weight of the dried plant, including flower head and leaves. The measurement must be carried out in an accredited laboratory in accordance with a forthcoming ministerial regulation.

Specifically, this notification revokes and replaces the Notification of the Narcotics Control Committee of August 30, 2019, which had set the THC limit for hemp at not more than 0.5 percent by dried weight.

This notification will not be enforced against any hemp plant or certified hemp seed that was approved prior to the announcement of the notification.
