Review:
What properties in drugs make them addicting?
Different drugs act on the brain in different ways, but they all cause release of the neurotransmitter dopamine in the brains reward area, which is what causes the pleasurable sensation (the high). Once a person uses a drug repeatedly, their brain starts to adjust to these surges of dopamine; the brain cells (neurons) make fewer dopamine receptors, or they simply produce less dopamine.
The result is a lower amount of dopamine signaling in the reward areaits like turning down the volume on the reward signal. Then the person may start to find natural rewardslike food, relationships, or sexless pleasurable; thats one of the signs of addiction.
Also, reduced dopamine signaling in the brains prefrontal cortex, which governs our ability to inhibit (slow down or stop) our impulses, makes it harder to resist the urge to take drugs even if a person would like to quit.
