Spice ampoules functioned as vessels designed to facilitate the movement of spice. Crafted from surgical plastic, these ampoules were surgically inserted beneath the skin of drug carriers, providing a clandestine means to smuggle spice without detection by security personnel. When properly sealed, each ampoule could maintain its integrity for a minimum of 12 hours. During the era of the Cold War, this practice gained considerable traction within the Black Sun criminal organization operating on Coruscant.
