A blood test showing illegal drugs in your blood stream while driving will almost certainly result in a drugged driving offense. Like driving under the influence of alcohol, drugged driving is a public health concern because it puts everyone at risk, the driver, passengers, and those sharing the road. Studies show drugs are used by 10 to 22 percent of drivers involved in crashes often in combination with alcohol. Marijuana, cocaine and amphetamines are some of the most common drugs detected in an impaired driver’s blood. If you’re charged with a drugged driving offense, contact an attorney as soon as possible to determine your legal options.
