Detailed answer
Onset depends on route: sublingual (under the tongue, 60–90 s) → 15–45 min. Inhalation (vape, smoked) → 5–15 min. Oral (capsules, gummies) → 30–120 min, lower bioavailability due to first-pass metabolism. Topical (creams) acts locally, no systemic uptake. Duration: 4–6 h inhaled, 6–8 h oral. For sleep: take 30–60 min before bed. Consistent daily use over 1–2 weeks can stabilise effects.
