A joint works differently from an edible – not just stronger or weaker, but also considerably different in duration. Why this is the case, and what it means for dosing.
One of the most common reasons for unintentional overdoses is a misunderstanding of duration of action. "I didn't feel anything, so I took more" – and then both doses kick in simultaneously. This happens almost exclusively with edibles.
## Inhalation (Smoking, Vaporising)
Onset: 2–10 minutes | Peak: 20–40 minutes | Duration: 2–4 hours
THC reaches the brain almost immediately via the lungs. Fast onset enables "titrating" – consume a little, wait briefly, assess, decide if more is needed.
## Oral Intake (Edibles, Oils, Capsules)
Onset: 30 min–2 hours | Peak: 2–4 hours after intake | Duration: 4–8 hours (up to 12 hours)
THC is converted in the liver to 11-hydroxy-THC, which crosses the blood-brain barrier more effectively. On an empty stomach: faster (30–60 min); after a fatty meal: 2+ hours.
Golden rule for edibles: Wait at least 2 hours before taking more. Even if you feel nothing.
## Sublingual (Oil Under the Tongue)
Onset: 15–45 minutes | Duration: 2–6 hours
Part of the THC is absorbed directly through the oral mucosa, part is swallowed and digested like an edible – potentially creating a biphasic effect profile.
## Quick Reference Table
| Method | Onset | Peak | Duration | |---|---|---|---| | Smoking | 2–10 min | 20–40 min | 2–4 hrs | | Vaporising | 5–15 min | 20–45 min | 2–4 hrs | | Edible (empty stomach) | 30–60 min | 90–180 min | 4–8 hrs | | Edible (after meal) | 60–120 min | 2–4 hrs | 6–12 hrs | | Sublingual | 15–45 min | 60–120 min | 2–6 hrs |
