Discover the truth behind driving after cannabis use and get expert advice on staying safe on the road.
There is no federal legal limit for cannabis DUI in the US. Each state sets its own rules, with some enforcing zero-tolerance (any detectable THC) and others using per se limits like 5 ng/mL of THC in blood. Understanding your state's law is crucial before driving after consuming cannabis.
Key Facts About Cannabis DUI Limits
- No federal limit: The US has no nationwide THC blood limit for driving.
- Zero-tolerance states: Many states, such as Arizona and Georgia, prohibit any detectable THC.
- Per se limits: Some states, like Colorado and Montana, set a legal limit, often 5 ng/mL of THC in blood.
- Impairment vs. presence: Some states require proof of impairment, not just THC presence.
- Medical cannabis: Even with a medical card, you can be charged with DUI.
- Testing methods: Blood, urine, and saliva tests vary in reliability and legal acceptance.
- Penalties: DUI penalties may include fines, license suspension, and jail time.
How Are THC Limits Measured?
Per se limits are typically measured as nanograms of THC per milliliter of blood (ng/mL). However, THC can remain in the bloodstream for days after use, long after impairment fades. This makes legal limit laws controversial, as they may not reflect actual impairment. Some states instead rely on field sobriety tests and officer observations.
