Methamphetamine is a synthetic recreational drug with highly addictive properties. Nutrients are the raw materials that the brain needs in very specific amounts to create neurotransmitters. What are neurotransmitters? Neurotransmitters and Addiction. Dopamine-depleted or dopamine-deleted animals have only unlearned reflexes; they lack learned seeking and learned avoidance. Lack of oxygen could also lead to brain damage. Specifically, the drug acts on the brain's reward system, a system in which certain neurotransmitters are affected. When dopamine remains in the synapse due to the presence of cocaine blocking reuptake, the sites on the neighboring neuron that detect the dopamine and pass the nervous signal on are overworked. Some other common neurotransmitters that play an important role in addiction are dopamine, serotonin, and norepinephrine.
