Hell. I'll post in this for shits and giggles.
"Third Eye" - While the drug has just recently come out into the general, public view, it has always been around. Originating from Akashima, Third Eye was originally used as a way for Spirit Warders to greatly improve their Sight abilities for a brief period of time - to the point that even those without any spiritual "eye" would be able to see into the realm of the supernatural for a time, as if they too possessed the 'Sight'. However, due to the fact that this would often cause users to go insane, Third Eye was disbanded from the public use and users of the True Sight would regulate it to Spirit Warders only, in small amounts.
However, a recent outbreak of Third Eye drug distributions to the public has caused wonder as to the intentions of the Akashiman Spirit Warders, and several gangs have formed to control the illegal distribution.
Effect: Allows user to possess a "Third Eye" for a short period of time, allowing them to see into the supernatural plane and adopt the True Sight, whereupon anything they see they cannot forget, ever, save a total case of amnesia.
Rarity: Uncommon - Rare. Recent outbreaks in Corone and Radasanth have made it easier to find at this point.
Application: Third Eye is a solid, gummy substance that is chewed, and upon chewing it releases endorphins to the consumer's brain, which allows it to temporarily increase activity and unlock True Sight. The effect lasts for the time spent consuming, and generally ten to twenty minutes past that, depending on the amount consumed.
Harmful Effects/Addiction Rate: While not being directly harmful to a person's body, the sights the "average" individual can see with True Sight often drive them insane with time as they cannot "unSee" what has been Seen with True Sight, if they are not trained to handle such. As it is, the addiction rate can also vary with the individual, but generally has a moderate (couple times a week) to extreme (at least once a day) rate.
