A report conveys that, regular medicine users can have complexity choosing between right and wrong, perhaps because the specific parts of their brains used for moral dispensation and evaluating emotions are damaged by their prolonged drug habits. There is strong link between drug use and illegal behaviour, but it is not known whether the criminal behaviour is in part a result of the drugs’ effects on brain function. Lead author Samantha Fede from University of New Mexico in the US conveyed that ,this is the first research to suggest impairments in the neural systems of moral processing in both cocaine and methamphetamine users. The investigator examined how the neural networks and brain functioning of chronic cocaine and methamphetamine users in US jails relate to their ability to evaluate and decide about moral situations or scenarios. Poor judgment about moral situations can lead to poor decision making and subsequent antisocial behaviour.
The investigator recorded the life the past of substance abuse of 131 cocaine and methamphetamine users and 80 non-users incarcerated in New Mexico and Wisconsin prisons. The member brains were scanned while they finished a moral decision-making task in which they evaluated whether certain phrases were morally wrong or not. Compared to the non-users, the regular stimulant users had abnormal neural activity in the forward lobes and limbic regions of their brains during moral processing.
