What Narcotics are highly addictive and affect the drivers?

Highly addictive narcotics include opioids such as heroin, fentanyl, and prescription painkillers like oxycodone and morphine. These substances can significantly impair cognitive and motor functions, leading to decreased reaction times and judgment. Drivers under the influence of these drugs are at a higher risk of accidents due to drowsiness, confusion, and impaired coordination. The use of such narcotics while driving poses serious dangers not only to the user but also to others on the road.
