Long, equatorial sativas dried and tied to bamboo skewers — the original Thai Stick. Brought to the West by US servicemen and became foundational to haze lineages.
Smoked socially across South-East Asia.
Traditional remedy for fatigue, low mood and headache. Modern Thai-derived sativas appear in UK formularies for fatigue and ADHD-adjacent symptoms.
Evidence note
Each claim below is tagged with the strongest available evidence type. Much of the historical and traditional record is ethnobotanical rather than clinical-trial grade. Modern UK prescribing of cannabis-based medicinal products is governed by the MHRA and guided by NICE NG144; individual suitability is decided by a specialist clinician. Nothing here constitutes medical advice.
