The Short Version
Social media and controlled substances like cocaine or heroin share some overlapping dopaminergic pathways and reward-circuit activation, but the claim that they produce "comparable" addiction overstates the evidence. Peer-reviewed research consistently describes "similarities" and "overlap" — not equivalence. Cocaine and heroin directly hijack neurotransmitter systems through pharmacological mechanisms fundamentally different from social media's behavioral reinforcement. The American Academy of Pediatrics explicitly calls this comparison "not accurate," and the scientific consensus classifies social media overuse as a behavioral addiction, categorically distinct from substance dependence.
