THC is a psychoactive cannabinoid that acts mainly through CB1 receptors in the central nervous system. Acute sedation does not necessarily translate into healthier sleep architecture or long-term benefit.
What it is, why people use it, the evidence, and what to know before trying it.
Regulatory status: legal and medical status varies by country and US jurisdiction; some THC medicines have FDA-approved indications, while cannabis products are not federally approved as sleep treatments
Evidence basis: Human clinical evidence
Known side effects, interactions and use limits from reviewed sources.
