Securicine

Securicine is a medication created by Biotechnica sometime prior to the 2070s.

Description
Securicine was a painkiller with the main side effect inducing gradual neurodegeneration with prolonged usage. This was a known side effect to Biotechnica and they decided that Securicine was too profitable to be pulled from the market. The information on this would be classified to Level 1 and higher access within the corporation.

However, Sasha Galina would infiltrate the Biotechnica's Night City HQ at Corpo Plaza to steal confidential records on other Biotechnica projects but stumble upon and accessed the side effects on Securicine that Biotechnica kept secret. Her mother had died of the neurodegeneration that Biotechnica left undisclosed, and this emboldened her to upload Biotechnica's entire database on Securicine to Network News 54 as her last act before being killed by Biotechnica security.
