Legalize Performance Enhancing Drugs: Coffee is an addictive drug.

These substances are human technologies. Human has to evolve freely.

"Drug is not a legal debate. Drug is a personal decision."

"Caffeine is considerably toxic to various animals, such as dogs and birds."

That means, chickens too.

Freedom and Liberty have to be respected by all. No one can oppressed anyone for using performance enhancing drug. And that includes usage on one's own animals.
