In the new Limitless TV series, the FBI provides NZT pills for Brian. In the movie, at the end of it, it was revealed that Morra monopolized the production of NZT and created a serum/injection that made the user immune to the side-effects of NZT.
In the series, Brian gets NZT pills from the FBI and from Morra (because he is a double-layered agent) and Morra provides him the serum.
How does the FBI provide the pills? Does the Bureau make them (it's illegal to produce drugs)?
