Why some people try it out is different than why people keep using it. Why people try it out can range from getting addicted after being prescribed something legal to wanting to escape life. Why people keep seeking it out/why they are addicted is hard to rationalize and understand and is like answering the question why do people like sex? You can't peer into your own mind, determine how its working and how you can manually change it. After addiction there usually needs to be some adverse event or events where people realize that the pain is greater than the pleasure, but there are still other people where even majorly adverse events don't change their rationale. Why people use fentanyl over other opiates is kind of simple. It is cheaper than everything else, there is a high supply of it, and it is stronger than everything else.

> Some people seek it out.

who's seeking it out? The article doesn't mention it, and the parent poster explicitly say that people are NOT seeking it out.

People that are already addicted may seek out the lowest cost opiate.

Yup.

Heroin will barely make some feel well.

Fent burns the Mu-opioid receptors, once normalized, H will barely get you high.

and, of course, you literally must have it - especially, to sleep.

It’s important to some people’s culture and religion.
