Question: Can Scarecrow's Fear Toxin Be Created in Real Life?
Ingredients: The Wiki of the Fear Toxin and DC universe doesn’t state what is used in the Fear Toxin but we can try to find an identical toxin in real life.
Our Answer: DMT and Agent 15
DMT: This hallucinogen is dubbed one of the strangest hallucinogen on the planet. You feel terrified at first then colors start to appear in different shapes and forms to the point where you feel like this is everlasting wonderland. This is however only when you inhale it but it is actually in all humans right now. It is a necessary part of our brain.
Agent 15: Used in the Cold War by Syria this was a gas dropped on soldiers to make them more aggressive or terrified in battle. The chemicals used are not known to this day however knowing the use we could speculate with the possibilities.
Final Statement: If we could chemically mix DMT and Agent 15 we might be able to create Scarecrow’s Fear Toxin.
