The mistake almost everybody makes
Nothing happened after forty minutes, so they took a second one, and then two hours of both arrived simultaneously. Waiting the full two hours is the entire technique.
Onset and duration by format
| Format | Onset | Duration | A conservative start |
|---|---|---|---|
| Flower or pre-roll | 1–10 minutes | 2–4 hours | One or two inhalations, then wait ten minutes |
| Vape | 1–5 minutes | 1–3 hours | One short draw, then wait five minutes |
| Concentrate | Seconds | 2–4 hours | A rice-grain amount |
| Edible | 30–120 minutes | 4–8 hours | 2.5–5 mg, then wait two hours |
| Tincture | 15–45 minutes | 4–6 hours | Half a dropper, held under the tongue |
| Topical | 10–30 minutes | 2–4 hours | Apply to the area; non-intoxicating |
If you have taken too much
You are not in danger, but you will be uncomfortable. Sit down somewhere familiar, drink water, and wait. It passes.
