Drug–impaired driving

Drug–impaired driving, also known as drugged driving, is the act of operating a motor vehicle while under the influence of drugs to the degree that mental and motor skills are impaired. It is a form of impaired driving and a serious public health concern. Drug-impaired driving encompasses the use of both illegal drugs and legal substances, including prescription medications and over-the-counter drugs, that can affect one's ability to drive safely.

Causes

Drug-impaired driving can be caused by a wide range of substances, including:

• Alcohol, though it is more commonly associated with alcohol-impaired driving, can also be involved in drug-impaired driving cases, especially when combined with other drugs.
• Cannabis, which can affect concentration, reaction times, and coordination.
• Cocaine and other stimulants, which may lead to reckless driving and increased risk-taking.
• Opioids, which can cause drowsiness and impair cognitive functions.
• Sedatives and tranquilizers, which can decrease alertness and slow reaction times.
• Prescription medications that warn against operating heavy machinery or driving.
• Over-the-counter drugs such as antihistamines, which can cause drowsiness.

Effects

The effects of drug-impaired driving can vary significantly depending on the type of drug and the amount consumed. Common effects include:

• Decreased reaction times
• Impaired judgment and decision-making abilities
• Reduced coordination and motor skills
• Altered perception of time and distance
• Increased risk of accidents and injuries

Legislation

Many countries have laws against drug-impaired driving, with varying definitions and penalties. In some jurisdictions, drivers may be prosecuted if they have detectable levels of certain drugs in their system, regardless of impairment. Other areas may require proof of impairment for a conviction. Laws often include:

• Zero tolerance policies for certain drugs
• Per se limits for drug concentration in the bloodstream
• Impairment-based evaluations and penalties

Detection

Law enforcement agencies use several methods to detect drug-impaired drivers, including:

• Field sobriety tests, which assess physical and cognitive function
• Drug recognition expert (DRE) evaluations, which involve trained officers identifying signs of drug impairment
• Chemical tests, such as blood, breath, or urine tests, to detect the presence of drugs

Prevention

Preventing drug-impaired driving involves public education, strict enforcement of laws, and support for individuals with substance use disorders. Strategies include:

• Educational campaigns to raise awareness about the dangers of drug-impaired driving
• Drug-free community programs
• Increased law enforcement presence and checkpoints
• Support and treatment programs for those struggling with drug addiction
