Benefits of Medical Cannabis on Ko Phangan
Updated for 2025: Thailand now permits cannabis strictly for medical use. As of June 26, 2025, cannabis flowers are regulated as a controlled herbal substance. Purchases require a valid prescription from a Thai-licensed practitioner, and public smoking remains prohibited. CBD and extracts below 0.2% THC are still allowed. This guide explains what that means on Ko Phangan and how to use cannabis safely and legally for health.

Evidence-Based Benefits
Medical cannabis may help certain conditions when supervised by a clinician. Effects vary by dose, chemovar (strain), route, and individual biology. The strongest evidence supports relief for some types of chronic pain and spasticity; there is emerging evidence for sleep and anxiety in select patients.
| Condition | What studies suggest | Typical cannabinoid profile* | Notes |
|---|---|---|---|
| Chronic non-cancer pain | Small improvements in pain and function vs. placebo with non-inhaled cannabinoids | Balanced THC:CBD or CBD-forward | Monitor for dizziness and sedation |
| Multiple sclerosis spasticity | Improved patient-reported spasticity in some trials | THC:CBD oromucosal | Start low; titrate slowly |
| Sleep problems/insomnia | Mixed but promising findings; some RCTs show sleep quality gains | CBD-forward; low-dose THC near bedtime | Avoid high THC if next-day grogginess |
| Anxiety (selected cases) | Signals of symptom reduction; evidence still limited/variable | CBD-forward; very low THC | Avoid high-THC in anxiety-prone users |
| Chemotherapy-related nausea | Established anti-emetic effects of certain cannabinoids | THC-inclusive under medical direction | Medical team supervision required |
*Talk to your clinician. Potency, terpenes, and drug interactions matter. Never change prescribed medicines without medical advice.

Choosing Products & Dosing Basics
Route affects onset and feel. Start low and go slow—especially with THC. Many patients begin with CBD-forward products and add small amounts of THC as advised.
| Form | Onset | Duration | Best for | Notes |
|---|---|---|---|---|
| Sublingual oils/tinctures | 30–60 min | 4–8 h | Steady relief; precise titration | Check THC% (≤0.2% for non-narcotic extracts) |
| Capsules/edibles | 60–120 min | 6–10 h | Nighttime use, prolonged effect | Avoid stacking doses—wait full onset |
| Vaporized flower | Minutes | 2–4 h | Breakthrough symptoms | Medical-only; use in private settings |
| Topicals | Local | Varies | Localized discomfort | Limited systemic effects |
Strains & Terpenes: What to Know
Beyond THC and CBD, aromatic terpenes shape the experience. Discuss terpene profiles with your clinician and dispensary pharmacist.
| Chemovar (example) | Common effect theme | Dominant terpenes | When to consider |
|---|---|---|---|
| Indica-leaning | Body-heavy calm | Myrcene, linalool | Evening, sleep support |
| Sativa-leaning | Uplift/clarity (some users) | Limonene, pinene | Daytime focus (CBD-balanced to reduce jitters) |
| Balanced hybrid | Even profile | Caryophyllene + myrcene/limonene | All-day comfort, pain modulation |
Safety, Side Effects & Interactions
