| Jurisdiction | Status | Rule | |
|---|---|---|---|
| Germany | Legal | THC limit for drivers: 3.5 ng/ml Driving with 3.5 ng/ml THC or more in blood serum is an administrative offence, normally a 500 euro fine and a one month driving ban. Novice drivers in their probation period and drivers under 21 may not drive with any THC, and mixing cannabis with alcohol is punished more severely. |

| Spain | Decriminalized | Any trace of drugs at the wheel is fined Driving with any detectable presence of drugs, including THC in a saliva test, is a very serious offence under the traffic law: a 1,000 euro fine and the loss of six points, regardless of impairment. Driving clearly impaired can also be a crime. |

| Switzerland | Decriminalized | Zero tolerance for THC at the wheel Switzerland applies zero tolerance: a THC concentration of 1.5 micrograms per litre of blood or more counts as unfit to drive, with a licence withdrawal and criminal charges. This also applies to legal CBD products if they push THC above the limit. |
