Special is the rarest of psidrugs and is available only in liquid form and must be taken by injection. Special gradually increases psionic strength points to human maximum over the course of 12 to 20 hours. Psionic strength remains at this level (if unused) for four hours, and then wanes at over the same period until psionic strength reaches zero. Normal recovery then occurs.
Special has some dangers and may permanently reduce Psi strength.
