Carsunum Black Spice

Carsunum Black Spice
Model: Black Sevari Spice
Type: Physical-enhancing drug.
Cost: 1,000 per dose
Availability: 4, X
Game Notes: Carsunum users become more intelligent,
faster, stronger, and generally more able. Users also
experience a mild euphoria and increased confidence. This
benefit has a dark side: after the effect wears off, users
become listless, sometimes poisoned, and occasionally
overdose fatally. Carsunum increases all abilities and
skills by +1D for 1D hours. At the end of the effect, the
user takes 1D damage for each hour under the influence
(the carsunum bonus cannot be applied). Force skills and
bonuses from Force Points are decreased by -1D per dose
for the appropriate period.

Carsunum was a rare and highly illegal spice variant mined on Sevarcos. Use of carsunum granted a boost of both mental and physical abilities as well as a pleasurable sense of well-being; however, once the spice hit ended, side effects could vary from jitters to death.
