That someone must have been misinformed.

The history of methamphetamine starts with a group of shrubs known as ephedra. These plants, found in many parts of the world, have been used for thousands of years in China, Pakistan, India and the Americas.

Also the more recent synthetic versions were created with a purpose: as a stimulant. Only after World War 2 it has been discovered that it is addictive.
