The phrase “the dopaminergic effects are not dissimilar to drugs and social media is just as addictive” is very unclear.

Very few people know what dopaminergic means. It might not be a real word.

“Is not dissimilar from” is a stock phrase used in an academia and by people trying to sound very smart.

The poster included just enough technobabble and stock phrasing to imply they are a specialist. But specialists know when speaking to non-specialists you should avoid technical language and stock phrasing.
