 The study found that amphetamine causes different effects depending on gender and age. In males, it caused damage to the brain's dopamine connections, leading to long-lasting cognitive impairments. However, in females, the drug had the opposite effect, causing the brain to compensate for the damage and prevent any lasting harm. This suggests that males are more susceptible to the negative effects of drugs than females at this stage of development. This article was authored by Lauren M.
