That very wikipedia article you links makes it clear it's not intended to mean religion is a "Drug" in the sense of being addictive, but rather a sociological pain killer. A tonic that limits how much people react to their own suffering.
(Merriam-Webster, "addiction")
It might be stretching it somewhat, but I think video games, social media, and religion can manifest a habitual need to indulge, negative effects from doing so, and negative effects from not doing so. Perhaps not in most people.
Coping mechanisms/painkillers can naturally cause some people to be "in too deep" because they keep using it and become dependent.
