PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -Stimulant drugs, including novel psychoactive substances (NPS, formerly “legal highs”) have addictive potential which their users may not realize. Stimulants increase extracellular dopamine levels in the brain, including the reward and addiction pathways, through interacting with dopamine transporter (DAT).

Detailed explanation-2: -The major neurotransmitter involved in reward and reinforcement is dopamine. Stimulants have profound effects on dopamine in the CNS. Cocaine blocks the reuptake of dopamine on the presynaptic neuron. Through dopamine, cocaine enhances reward and causes euphoria.
