Answer:
Coca-Cola
Explanation:
The original recipe for Coca-Cola was using cocaine until 1904, hence its name.
Of course, cocaine is a brain stimulant. It was first mixed in the recipe to help quit addiction to the morphine of its creator, a pharmacist with chronic pain issues.
Drinks mixed with now-illegal drugs were common around year 1900... there was wine with cocaine, mixes with arsenic and many other drugs.
