Cannabis edibles — the Swiss guide

Edibles work slower but harder — the liver turns THC into 11-OH-THC. The classic beginner mistake: re-dosing before the first serving kicks in.

Onset 30–120 min, peak 2–3 h, duration 6–8 h, hangover up to 12 h. Beginner THC dose: 2.5 mg. Standard: 5–10 mg. CBD edibles < 1 % THC: legal but often in Novel Food gray zone. THC edibles: illegal outside prescription.

Why edibles work differently

Swallowed THC passes through the liver, where CYP2C9 converts a large share into 11-OH-THC — 3–5× more potent at the CB1 receptor.

10 mg eaten feels like ~40 mg smoked in intensity — slower, body-heavier, more sedating.

Dosing rules

Start: 2.5 mg THC. Wait 2 h before re-dosing.

Standard: 5–10 mg.

Forms

Gummies: exact dosing (2.5–10 mg).
