Heroine was created by Bayer,
For medicinal purposes,
It was named Heroine because it made people feel like a Hero,
Eventually it was determined to be addictive,
LSD comes from the Ergot fungus,
A naturally occurring fungus that primarily grows on Rye and can grow on many grasses.
Several people were executed in Salem Massachusetts for Ergotism,
They accidentally consumed Ergot during a wet summer,
Most of them lived in a swampy area of the town.
It took 300 years for the mysterious cause to be discovered.
