Mmm...maybe? I just got back into reading fiction after uhh...almost two decades from the last time I read fiction. I've also been addicted to alcohol and weed in the past. And I've also NOT been addicted to, but used to occassionally enjoy, psychedelic mushrooms. I've also been addicted to exercise, sports, and work.

To me, effective fiction, if comparable to any class of drugs, is closest to psychedelics, and is far less similar to other much more addictive and usually harmful drugs. Both fiction and psychedelics can change your worldview without necessarily having to go through a potentially traumatic experience (though in both the reading of fiction and the experience of psychedelics, it's important to note that trauma can still happen).

Any activity can be addictive. Determining whether an activity is addictive can be based off of whether or not said activity harms your current relationships, damages your physical/mental health, or prevents you from otherwise having a fulfilling life. Thusly whether or not an activity or substance is addictive is somewhat subjective, and dependant on the context under which said activity/substance is participated in/consumed.

Sometimes the desire to obliterate one's sense of self through addiction stems from a turmoil/pain that is markedly worse than the intoxication/numbing they get from their substance/activity of choice. Sometimes there are no support structures or alternative ways of addressing your issues and/or pain.

I'm not trying to downplay or ignore the very serious problem of addiction, as I think addiction pervades nearly every aspect of modern life in both subtle and overt ways, but I do think that we all tend to judge each other for our addictions rather than question why we all seem to have these various addictions in the first place, and I question whether or not our ire and concern would be better redirected at the political socioeconomic conditions that generate these cultures of addiction in the first place.
