This thread is really not about heroin, though. Take food as an example. A person can be addicted to food (https://en.wikipedia.org/wiki/Food_addiction) but eating isn't otherwise necessarily unhealthy. A person may be "compelled" to take a certain action for many reasons; I fail to see how the use of that word in this title is wrong.
The sine qua non of addiction is withdrawal symptoms, not compulsion. Social media isn't necessary if you have a productive social life replacement. There is no analog substitute for heroin.
> The sine qua non of addiction is withdrawal symptoms, not compulsion.
This statement refutes the idea that social media or food can possibly be addictive, yet there's this body of research for both which asserts they can be. At best, this is splitting hairs over the definition of addiction. Assuming that Something can be addictive, a person might be "compelled" to act by their addiction to Something.
