18+ topic. Is there zero tolerance for drug driving in Denmark?
A near-zero limit for illegal drugs.
Short answer
18+ topic. You may not drive in Denmark with illegal drugs in your blood, and the limit for THC from cannabis is 0,001 mg per kg of blood. Between 0,001 and 0,003 you get a point on your licence and a fine of half a month of net pay. Between 0,003 and 0,009 the fine is one month of net pay plus conditional disqualification or a driving ban, and above 0,009 the licence goes unconditionally for 3 years. For other illegal drugs the penalty is the same as for drink driving at 1.21 per mille, with 3 years of unconditional disqualification.
Why
- THC limit 0,001 mg per kg of blood.
- Penalties rise in three THC steps.
- Other drugs count like 1.21 per mille.
Details
THC acid can be found in urine much longer than in blood, but only the THC level in the blood counts as evidence.
Tip
Do not drive at all after using cannabis or other drugs, even if you feel fine.
What may differ
Drugs taken under a valid prescription are treated differently, and repeat offences raise the penalty.
Common misconception
A little cannabis the day before does not matter if you feel sober.
What actually happens
The THC limit is close to zero, so even small traces in the blood can be punished.
