Keep in mind that every "Dopamine does ____" is an extreme simplification. Dopamine is a neurotransmitter that is used by a number of different neurons throughout the brain, as well as in different roles in the body outside of the brain.

This article, like every study of dopaminergic neurons, is about specific neurons that happen to use dopamine for some of their signaling. It's incorrect to extrapolate this to generalizations about what dopamine does or does not do, because it depends on the specific neurons.

Why dopamine makes some people more impulsive. Maybe I'll give the article a closer read tomorrow morning after the amphetamines kick in, until then, I'll smirk in ADHD

I seem to be one of the few people who don't like dopamin rushes.

I hate myself for 2-5 hours after intense sports. When I still did go to the gym I had to avoid people afterwards, each time.

Same for cocaine, it's fun. Sure is, but I don't like the personality I get. Nether do others.

I did Alcar (some dopamine level pushing nootropic) for a while. I loved it, but everyone started to beg me to stop it.

I still have no idea why I can't have fun with dopamine. Or what this ultimately means for me.

Huberman Lab podcast on dopamine was a really cool listen. [1]

Important takeaway: coffee does not lower the baseline dopamine level. Yes!

For anyone interested in reading more about dopamine, this[1] is a great read imho. It also includes references for the claims and further reading.

And yet dopamine is what make ADHDers focused.
