Methamphetamine damages neurons through oxidative stress and dopamine-mediated neurotoxicity.
Extensive scientific literature consistently demonstrates that methamphetamine induces neuronal damage through oxidative stress mechanisms driven heavily by altered dopamine dynamics.
Every retrieved paper explicitly supports the claim that methamphetamine-induced neurotoxicity involves oxidative stress and dopamine-related mechanisms. The papers range from primary experimental studies showing intracellular oxidant production and receptor involvement to comprehensive reviews detailing how methamphetamine-evoked dopamine release generates reactive oxygen species, leading to dopaminergic terminal degeneration. Therefore, the balance verdict is SUPPORTED.

LaForge et al. (1994) demonstrate that methamphetamine redistributes dopamine, causing intracellular oxidative stress that triggers dopaminergic terminal loss.
