CBD (cannabidiol)
Sleep · Non-psychoactive cannabinoid
Tier B
What this is
Consumer CBD product quality varies enormously — cannabiscore/third-party testing essential. FDA has not created supplement regulatory pathway for CBD despite Farm Bill 2018. Sleep evidence is thinner than popular perception suggests; anxiolytic signal is slightly stronger. Drug-drug interactions (especially with warfarin, SSRIs, antiepileptics) are real and underappreciated.
Mechanism
Partial CB1 agonist/allosteric modulator; 5-HT1A agonist; GPR55 antagonist; anti-inflammatory; FDA-approved (Epidiolex) for rare epilepsies; non-intoxicating
Dose & route
25-300 mg/day PO (supplement range); 10-20 mg/kg/day (Epidiolex)
