From everything I have read about addiction, it is far from that simple. One of the best examples are pain medicine like morphine. Give opioids to patients and some will form addiction to it and others will not, and the predictors for that are both genetic and environmental. It is not as simple as inject it into person X and now they are a slave to it. One way one can see this is in statistics in that long-term opioid use occurs in about 4% of people following their use for trauma or surgery-related pain.

It not at all certain that you would find it hard to stop if you suddenly decided to try smoking. There would naturally be a risk, but how high that risk is is a debated subject if you have none of the risk factors for addictions.

You’re being downvoted, but there’s an interesting point you’re trying to make. Dopamine-chasing is truly selective in the behavior and chemical sense.

There is a particular hard drug that I could be easily addicted to if it were cheaper and more accessible. Nothing else like it gives me irresistible craving for more. Not nicotine, ADHD meds or speed, benzos, and not even opioids have the same effect. So after I discovered this about myself, I went on a little journey to self test myself other possible addictions.

Social media? Nope. Video games and tv? yes. Gambling, hoarding, shopping: No. Sex: yes. Exercise: yes

I can’t rationalize any of it.

And yet, some people find themselves compelled to continue gambling long after they’re drowning in debt.

If you don’t want to call that addiction, fine, but you can’t deny that it happens.
