I remember a mini-series or failed pilot from the late-80s or early 90s.
A Jimmy Smits-type cop investigated a new addictive Virtual Reality tech that kills its users. It used a small coin-sized disk that plugged into your brain.
The bad guy’s HQ was the Los Angeles Pacific Design Center (the Big Blue Whale building). The main character's BFF was a black guy who overdosed and dragged the cop into the case.
