This is a close relative of Calm, but it creates a sense of peace and happiness in the user, a feeling of being truly content and happy. In addition to the effect of Calm, it stimulates part of the pleasure centers of the brain. Overdosing can cause hatred of reality.
The pheromone drugs take the form of 1 ½ long metal cylinder, with one smooth, rounded end, and another flat one. The pheromone drug can be either drunken, or injected, which it allows by a chemical in the concoction which makes cells extremely absorbent. As such if you press the cylinder to your arm (or whatever part of your body you wish), and press the rounded end, your arm will quickly absorb the chemical, it will quickly reach the blood stream and come into effect. It can also be drunken by unscrewing the flat end and simply drinking it, the fluid being absorbed in the mouth or when going down the throat. It is rare for any of it to reach the stomach.
In the capsules the amount of the pheromone is measured very specifically, and if taking just that capsule, there should not be any problems, taking more than that can cause serious difficulties.
