Cannabis cross-border Germany ↔ Switzerland — the complete guide
Roughly 60,000 commuters cross the DE–CH border daily. Since CanG 2024, two legal systems meet head-on. This guide explains what's allowed.
Core rule: cannabis must never cross the border. Basel/Konstanz/Rheinfelden customs use K9 units. Over 10 g: prosecution under BetmG.
German rules (CanG)
In DE: 25 g possession, 50 g at home, 3 plants home-grow. Purchase via CSC or personal cultivation only.
Swiss rules (BetmG)
Cannabis > 1 % THC = narcotic. Up to 10 g: CHF 100 fine. Above: criminal case.
At the border
Customs can search without suspicion. Sniffer dogs alert from 0.5 g residual smell. Even an empty bag can trigger a report.
FAQ
5 g bought legally in DE — can I take it into CH?
No — BetmG Art. 19 bans import regardless of German legality.
Does CBD oil trigger a drug test?
It can — tests react to THC. Carry the invoice and lab report.
