大麻二酚 CBD × 失眠
The totality of evidence does not support pure CBD as an effective treatment for insomnia.
The totality of evidence does not support pure CBD as an effective treatment for insomnia. Both dedicated 150 mg pure-CBD primary-insomnia RCTs (n=30 each) were NULL on every primary insomnia outcome, and a 2025 meta-analysis of 6 RCTs (1077 patients) found that CBD-only therapies have NO statistically significant effect on subjective sleep quality, with the positive signal coming exclusively from THC/CBN-containing products. The American Academy of Sleep Medicine explicitly advises against routine cannabinoid use for any sleep disorder and notes a scoping review where 48% of studies reported worsening sleep versus only 21% reporting improvement. Examine has no CBD-insomnia outcome block at all (coverage gap), and Cleveland Clinic, Mayo Clinic researchers, and Harvard all characterise the evidence as inadequate or preliminary, with Harvard's mildly optimistic framing resting partly on cannabis/THC rather than pure-CBD data. Grade D is assigned because the best-quality, condition-specific pure-CBD evidence is negative-to-negligible, a recognised authority actively discourages use, and CBD additionally carries serious drug-interaction and hepatotoxicity risks (L9) plus prescription-only / unlawful-as-food regulatory status in Taiwan, the US and the EU. A C grade would overstate a body of evidence whose dedicated trials all failed.
評分透明度
所有分數由 7 層證據引擎計算，過程公開可查▸查看完整決策路徑（audit trail）
- compute_raw_score — 加權公式: L2×0.30 + L3×0.25 + L5×0.25 + L11×0.10 + L1×0.10 = 0.386
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 高階證據未達主導 (1 positive vs 1 negative)，由 raw_score 決定
- tier_strict_requirement_check — Tier 條件達標，未降階
- detect_disputes — 偵測到 0 個 hard + 1 個 soft dispute
- decide_status — 依 tier + dispute 結果決定 status
PTT（Health/MuscleBeach/MenTalk）與 Dcard 社群對 CBD 助眠討論熱絡，部分人反映半小時內入睡、夜間醒來次數大減、長輩睡得深，回饋偏正面；但也有健身族指台灣合法純 CBD 效果「微妙」、時有時無，且須海外代購、單價高，整體經驗分歧、業配密度高。
分歧（助眠回饋偏正面，但台灣合法純 CBD 多人反映效果微妙或無感，且屬個人經驗、非研究證據）
- 嗜睡、隔日易睡過頭（需設鬧鐘）
- 初次過量產生不適或過 high 感（多見於併用 THC 全光譜時）
- 部分人反映無感或反而較難入睡（效果因人而異）
- 失眠認知行為治療（CBT-I）
- 睡眠衛生與刺激控制
