Driving while under the influence of drugs is included as a DUI under Massachusetts law and carries the same penalties, civil and criminal. The tragedy that can result when drivers operate their vehicles when drunk or high was highlighted recently in a concluded trial in Worcester. The defendant was allegedly under the influence of marijuana when his Nissan Maxima collided at around 80 mph with the rear of a police cruiser, killing the officer. A nurse testified that the defendant told her that he had a medical prescription for the drug and had fallen asleep before the collision. His doctor said he had had a compulsive episode or seizure just before the collision that was the real reason for the accident. It is not known if the defendant had taken a blood test for the presence of THC in his system or if he had admitted to using marijuana before driving.
