Yes. The over-simplification of dopamine as some sort of pleasure chemical is frustratingly common. Everyone seems to want to be able to explain every emotion and behavior as the byproduct of a neurotransmitter, e.g. "I'm addicted to the dopamine hits from my phone", "I'm sad because my serotonin is low", "I'm on an endorphin high from that workout", etc. etc. Besides many of these examples being flat-out wrong, emotions in general are immensely more complex than the simple release of a single chemical in the brain. The belief that everything bad in the brain is just a "chemical imbalance" is a really harmful one IMO, as it turns people away from truly understanding their problems, and replaces any sort of deeper understanding with a desire to simplify everything down to pseudo-scientific brain chemistry quick fixes.
