Neutron Pixie was an extremely potent, hallucinogenic spice with an unknown origin. Effects included ecstasy, increased reaction time, perceived feelings of strength and endurance, and resistance to pain. Withdrawal symptoms included perspiration, nausea, weakness in the muscles, aching bones or joints, and extreme physical and mental torpor. It was often ingested with a light fruit flavoring. Outlawed by the Galactic Empire, the spice was commonly sourced from smugglers.
