In my opinion and experience, it's just another addiction, it's enacting the pleasure-reward-aversion circuits in a human's brain. Whether it be alcohol, drugs, social media, OCD, over-eating, gambling etc. There are slight neuro-chemical nuances, of course, for each addiction, but similar neuro-pathways are involved.
I've read that humans are hard-wired to seek instant gratification and the modern day age provides plenty of those. Sadly, our brains haven't kept pace, but there is good news. Human's have developed a powerful neo-cortex that is an effective inhibitor of the lower brain instant gratification focus. Aristotle discovered this power all those years ago, the rational brain can trounce the lower brain pleasure, avoidance, auto-pilot comforting bias.
If there is a God, and I hope there is, s/he gave us free-will, aka neo-cortex, which distinguishes us from the reptile/mammalian brain, we have triune brains, which we can apply to our advantage in times of addiction adversity.
