What happens when you mix alcohol with other drugs while driving?
Quick Answer
Mixing alcohol with other drugs — including prescription medications, over-the-counter drugs, or illegal substances — multiplies the impairment effect. The combination can be far more dangerous than either substance alone. Even a small amount of alcohol combined with antihistamines or pain medication can severely impair driving ability.
