Everyone is afraid of bad trips or bad or Lucid nightmares, simply because they are unexpected. But sometimes all you want is to be afraid. I would like a dose that causes your brain to be scared and paranoid.
Making this a hallucinogen would be a bad idea. When you fear something and you're on a hallucinogen, you're chances of having a bad trip are greatly increased. This is caused from having a fear about the drug (parent's coming home, having to drive later, afraid you'll have a bad trip etc.).
Although most people would disagree i would like to see a fear/paranoia inducing dose. It would have a niche market much like masochist, but i believe it would be quite popular, and i for one would get it.
