Hm? Of course you can have an addiction to social media, you can get addicted to anything that produces dopamine in your brain.

Addiction to digital media is 100% real. People have destroyed their lives over addictions to certain video games, pornography, social media, and pretty much anything on the internet. hell, pretty much every game on the Android and Apple app stores are designed with addiction in mind.

I know a lot about addiction. Social media is not physically addictive, but anything can be a habit. Caffeine is physically addictive. People will say they have a workout addiction, too, but I don't think anything that delivers a natural high is an addiction. Addiction is when chemicals fool your brain into thinking it needs different stuff than normal. You're not addicted to oxygen, food, etc. Those are needs. When something substitutes itself for eating, like meth, you're addicted. When something becomes a physical need beyond the natural stuff like food and water, it's an addiction. Now, we don't always talk about medical treatments in those terms -- we don't need to -- but you can become physically dependent on medical treatment.

Stuff that makes you happy is just stuff that makes you happy. Social interaction can be disordered. When it is, we talk about it in different terms. We say someone is a narcissist, not that they're addicted to attention, except metaphorically. Typically, it's avoiding social interaction, rather than relishing it, that is disordered. That's because it's as much a need of humans as food and water. Yet the relationship between humans and interaction can be as disordered as the relationship between a bulimic and food.
