Opiates

Nerve Cells Experience Addiction & Withdrawal

What happens to make a person and his or her brain become addicted to an opiate? Long term opiate use changes the way nerve cells in the brain work. These cells grow so used to having the opiate around that they actually need it to work normally.

If opiates are taken away from dependent nerve cells, many cells become overactive. Eventually, these cells will work normally again, but in the meantime, they cause a wide range of symptoms in the brain and body. These are known as withdrawal symptoms.

Have you ever had the flu? You probably experienced symptoms such as aching, fever, sweating, shaking or chills. These are similar to withdrawal symptoms, but withdrawal symptoms are much worse. Yuck!
