Meet The Weed Effects

THC is proven to slow reaction time, reduce focus, and temporarily weaken problem solving skills. Consuming THC affects you differently than alcohol, but it impairs driving ability all the same. CDOT’s Meet The Effects Campaign is committed to raising awareness of the dangers of driving high. When someone is high behind the wheel, the chances of a crash are doubled, and the chances of a DUI are even higher. The average cost of a DUI is $13,500 for alcohol and drugs. Keep your high harmless and off the road.
