Cannabis Medical Use Index

Strains and cannabinoids organized by condition — anxiety, pain, sleep, PTSD, nausea, and more. Based on user reports and available research.

⚠️ This presents user-reported benefits and research findings. Cannabis is not FDA-approved to treat medical conditions. Always consult a qualified healthcare provider.
🧘

Anxiety

Cannabis has a complex relationship with anxiety. High-THC strains can worsen anxiety in some users while providing relief in others. CBD-dominant strains are most reliably anxiolytic.

✅ What Helps
  • High CBD content (5%+)
  • Low to moderate THC (under 15%)
  • Terpenes: Linalool, Limonene, Caryophyllene
  • 1:1 or higher CBD:THC ratios
  • Micro-dosing THC (2–5mg)
⚠️ Avoid
  • ×Very high THC (20%+) without CBD
  • ×Stimulating sativa-dominant if sensitive
  • ×Edibles (harder to dose accurately)
🌿 Reported Strains
📋 Note: User reports suggest benefits. Not a substitute for professional mental health treatment.
💊

Chronic Pain

The #1 medical cannabis use. THC activates CB1 receptors that modulate pain, while CBD and caryophyllene reduce inflammation at the source.

✅ What Helps
  • Balanced THC:CBD ratios
  • Indica-dominant for body pain
  • Terpenes: Caryophyllene, Myrcene, Humulene
  • Topicals for localized pain (CB2 receptors in skin)
⚠️ Avoid
  • ×Pure CBD alone may be insufficient for severe pain
  • ×Daytime high-THC affecting daily function
🌿 Reported Strains
📋 Note: Reports support use for neuropathic pain, arthritis, and fibromyalgia. Consult a physician for chronic conditions.
😴

Insomnia & Sleep

Cannabis reduces sleep onset time. CBN (formed as THC ages) is strongly sedating. However, regular high-THC use suppresses REM sleep over time.

✅ What Helps
  • High myrcene content
  • Indica-dominant strains
  • CBN-rich products
  • Terpenes: Myrcene, Linalool, Caryophyllene
⚠️ Avoid
  • ×Sativa-dominant strains
  • ×Stimulating terpene profiles (limonene, pinene)
  • ×Using nightly long-term — reduces REM sleep
🌿 Reported Strains
📋 Note: Best used situationally rather than nightly to preserve sleep quality and prevent tolerance.
🌤️

Depression

Cannabis can provide temporary mood elevation but heavy daily use is associated with worsened depression over time. Strategic use of uplifting strains can help.

✅ What Helps
  • Limonene-rich strains (uplifting)
  • Balanced or moderate THC
  • Pinene for mental clarity with mood lift
  • CBD for baseline mood support
⚠️ Avoid
  • ×Heavy daily use (may worsen long-term)
  • ×High-THC indicas (can increase sedation/low mood)
🌿 Reported Strains
📋 Note: Heavy regular use may worsen depression. Professional support strongly recommended.
🛡️

PTSD

One of the most promising areas for medical cannabis. The endocannabinoid system regulates fear extinction. THC can suppress nightmares and reduce hyperarousal. Several US states list PTSD as a qualifying condition.

✅ What Helps
  • Moderate THC for nightmare suppression
  • CBD for daytime anxiety component
  • Myrcene and linalool for calming hyperarousal
⚠️ Avoid
  • ×Very high THC that triggers paranoia (counterproductive)
  • ×Stimulating strains that increase hyperarousal
🌿 Reported Strains
📋 Note: Growing clinical evidence supports cannabis for PTSD. Best used alongside evidence-based PTSD therapy.
🤢

Nausea & Vomiting

THC's anti-nausea effects are so well-established that synthetic THC (Marinol) has been FDA-approved since 1985. Cannabis activates CB1 receptors in the brain's vomiting center.

✅ What Helps
  • Any THC-containing strain
  • CBD enhances via 5-HT1A receptors
  • Fast-acting inhaled methods for acute nausea
⚠️ Avoid
  • ×Edibles for acute nausea (too slow)
  • ×Harsh smoke if nausea is already severe
🌿 Reported Strains
📋 Note: One of the best-supported medical applications. FDA approved synthetic THC for this use in 1985.
🔥

Inflammation

Multiple anti-inflammatory mechanisms: CBD reduces inflammatory cytokines, caryophyllene binds CB2 receptors, humulene acts similarly to dexamethasone (a steroid) in studies.

✅ What Helps
  • High CBD for systemic inflammation
  • Caryophyllene-rich strains (CB2 activation)
  • Humulene terpene
  • CBG for IBD
  • Topicals for joint/localized inflammation
⚠️ Avoid
  • ×Smoking (introduces inflammatory compounds from combustion) — vaporize or use edibles/topicals
🌿 Reported Strains
📋 Note: Strong anti-inflammatory evidence for CBD and caryophyllene. Topicals particularly effective for joints.

Frequently Asked Questions

What cannabis strains are best for anxiety?+
High-CBD, low-THC strains are most reliable: ACDC, Harlequin, Cannatonic. Look for linalool and limonene terpenes. Avoid very high-THC strains without CBD — they can worsen anxiety. Micro-dosing (2–5mg THC) is also effective.
Does cannabis help with chronic pain?+
Chronic pain is the #1 reported medical use. THC activates CB1 receptors, CBD and caryophyllene reduce inflammation. Balanced THC:CBD ratios are often most effective. Topicals work on CB2 receptors for localized pain without psychoactive effects.
What strains are best for sleep?+
Indica-dominant strains high in myrcene: Granddaddy Purple, Northern Lights, Bubba Kush. CBN is strongly associated with sedation. Use situationally rather than nightly to preserve sleep quality and prevent tolerance.
Can cannabis help with PTSD?+
PTSD is one of the most researched medical cannabis applications. THC can suppress nightmares and reduce hyperarousal. Many US states list PTSD as a qualifying condition. Best combined with evidence-based PTSD therapy.
