The drugs quickly activate the brain's reward system - a primitive neurological circuit buried beneath the cortex - and release dopamine. This neurotransmitter, which is central to pleasure and desire, sends a message to the brain: This is an important experience worth remembering. Through this, the body begins to ask for the sensation released by dopamine, causing the body to become addicted to the substance.
