Cannabis consumption methods — the complete Swiss guide

Vaporizer, joint, bong, edibles or tincture — how you consume cannabis decides onset, duration, intensity, and health risk.

Inhalation (vape > joint > bong): effect within seconds–5 min, duration 2–4 h, bioavailability 20–35 %. Sublingual: 15–30 min, 4–6 h, ~20 %. Oral (edibles): 30–120 min, 6–8 h, 4–20 % — hard to dose, main cause of overdose ER visits. Dry-herb vaporizer is the cleanest inhalation. Beginners: sublingual oil with mg/drop label.

The four core routes

Combustion inhalation (joint, bong, pipe): fastest onset but smoke contains CO, tar, PAHs. Worst route for regular use.

Vaporization (dry-herb vaporizer, vape-pen): cannabinoids released at 170–210 °C without burning. Same speed, far fewer toxins.

Bioavailability — why the route multiplies the dose

Bioavailability = share of active compound reaching the bloodstream. Inhaled 20–35 %, sublingual ~20 %, oral 4–20 %.

10 mg THC in an edible feels stronger than 10 mg smoked — not because more arrives, but because 11-OH-THC is more sedating.

Which method for which goal?

Fast, controllable effect: vaporizer or joint.

Steady effect for hours: sublingual oil or edibles.

Swiss legal framework

CBD products < 1 % THC: free sale and consumption, any route allowed. Tobacco tax (25 %) on smokable products.

THC cannabis outside prescription or a pilot project remains illegal, regardless of method.

FAQ

Healthiest method?

Dry-herb vaporizer or sublingual oils — no combustion.

Why do edibles hit so hard?

Liver converts THC into 11-OH-THC, which is more sedating than inhaled THC.

Duration by method?

Inhalation: 2–4 h. Sublingual: 4–6 h. Edibles: 6–8 h (sometimes 12 h).

Can you vape a sublingual oil?

No — carrier oils (MCT, hemp seed) cause lipoid pneumonia when inhaled.

Worst method?

Joint with tobacco: combustion toxins plus nicotine dependence.
