Thai Haze

Thai Haze is a sativa-dominant hybrid that brings together the best of two legendary genetic lines — a pure Thai landrace and the world-renowned Haze. The result is a high-energy strain that combines the tropical character of Thai cannabis with the soaring cerebral effects that Haze is famous for. With THC levels reaching up to 24%, Thai Haze delivers a potent and long-lasting experience.

Effects & Experience

The high from Thai Haze comes on quickly with a rush of euphoria and mental clarity. Creativity flows freely, and users often feel a surge of motivation and energy that makes this an outstanding daytime strain. The uplifting effects are sustained over several hours, gradually tapering into a gentle sense of contentment. It is particularly effective for combating depression, fatigue, stress, and appetite loss.

Growing Information

Thai Haze inherits the growing challenges typical of sativa-dominant genetics. Plants can stretch considerably during flowering and require ample vertical space. The flowering period of 10 to 12 weeks is shorter than a pure Thai landrace but still longer than most hybrids. Growers in Thailand benefit from the natural tropical climate, which closely mirrors the conditions this strain thrives in. The difficulty level is rated hard, but experienced cultivators are rewarded with aromatic, resinous buds.

Availability in Thailand

Thai Haze crosses a Thai landrace with Haze, so it sits between the old Thai sativas and modern hybrids in potency. Since 26 June 2025, cannabis flower in Thailand may only be sold to a patient holding a PT 33 prescription from an authorised practitioner, and it is the practitioner, not the shop, who decides the product and the dose. Seeing a strain on a shop menu is not a reason to buy it. If you think cannabis could help a medical condition, start with a licensed clinic. Our PT 33 guide explains how the prescription works.
