Addictions come in many forms. Some seem obvious – like drug or alcohol addiction – but in this day and age, it's not uncommon for a person to develop an internet addiction. Researchers estimate that 6% of the world's population is addicted to the internet (that's about 420 million people!).
Internet addictions are described as an impulse control disorder that does not include the use of an intoxicating drug. It is oftentimes compared to pathological gambling. Internet addictions use the virtual fantasy world to connect with real people through the internet, as a substitution for real-life human connection, which most are not able to achieve face-to-face.
