Reference 29 - Berman S, O'Neill J, Fears S, Bartzokis G, London ED (2008). "Abuse of amphetamines and structural abnormalities in the brain", at least according to the abstract is not relevant to amphetamine. It is about the abuse of amphetaminES, but amphetamine appears not to be among the drugs considered in the reviewed literature. From the abstract: "Ten studies compared controls to individuals who were exposed to methamphetamine. Three studies assessed individuals exposed to 3–4-methylenedioxymethamphetamine (MDMA)."
