I was watching Almost Human, and it gave me an idea for a drug.
In the show, the drug is called Verum(Veh-rum). "It expands the mind, it opens it up to things in the universe that people are not supposed to see, enables people to realize their full potential."

Now, I was thinking that the drug would have the same abilities, to some extent, but have horrible side effects. I would have to think about them, but I think something along the lines of continued use results in increased brain aging or something, so the brain would age so quickly, it dies out after a while, or something like that. Also, I think this drug would be more accessible to Alpha districts, and drug distribution would be run by the Mafia-type gang. And then somehow, it gets to the Beta districts.
