Virtual-reality addiction is an addiction to the use of virtual reality or virtual, immersive environments. Currently, interactive virtual media (such as social networks) are referred to as virtual reality,[23] whereas future virtual reality refers to computer-simulated, immersive environments or worlds. Experts warn about the dangers of virtual reality, and compare the use of virtual reality (both in its current and future form) to the use of drugs, bringing with these comparisons the concern that, like drugs, users could possibly become addicted to virtual reality.[citation needed]
