Note: These PET scans compare the brain of an individual with a history of cocaine use disorder (middle and right) to the brain of an individual without a history of cocaine use (left). The person who has had a cocaine use disorder has lower levels of the D2 dopamine receptor (depicted in red) in the striatum one month (middle) and four months (right) after stopping cocaine use compared to the non-user. The level of dopamine receptors in the brain of the cocaine user are higher at the 4-month mark (right), but have not returned to the levels observed in the non-user (left).
Tobacco: Nicotine replacement therapies have several forms, including the patch, spray, gum, and lozenges. These products are available over the counter. The U.S. Food and Drug Administration (FDA) has approved two prescription medications for nicotine addiction: bupropion (Zyban®) and varenicline (Chantix®). They work differently in the brain, but both help prevent relapse in people trying to quit. The medications are more effective when combined with behavioral treatments, such as group and individual therapy as well as telephone quitlines.
Neurons communicate with each other by sending messages along axons and dendrites via electrical impulses. The axons turn these impulses into chemical signals, sending neurotransmitters across synapses. The receiving dendrite then converts neurotransmitters back into the right electrical signals, so we understand the message; for example, that bite of pie was delicious, I’ll take another one. These exchanges happen countless times in the brain, and they control mood, behavior, movement, and cognition.
For individuals addicted to prescription drugs, treatments tend to be similar to those who are addicted to drugs affecting the same brain systems. Medication like methadone and buprenorphine can be used to treat addiction to prescription opiates, and behavioral therapies can be used to treat addiction to prescription stimulants, benzodiazepines, and other drugs.[6]

The most common outpatient treatment is counselling (group or individual talking therapy, typically occurring once a week for an hour at a time, for six to 12 weeks). It may also include case management (help with accessing other services such as housing, medical or mental health services) or pharmacotherapy (prescribed medicine, such as methadone for opiate dependence).

How to Choose a Drug & Alcohol Rehab Center
Research the history of the Treatment Center or facility.  What is their success rate?  Can you find any medical recommendations for them online from members of the established rehab or medical community?  How long has the Center been in operation?  Is their leadership on solid ground?  Are there any signs of financial corruption associated with the Center that is readily visible on the Internet?  It is your responsibility to dig for this information.  If you cannot find any information about a given Treatment Center online or at your local library, move on to the next Center on your list! 3 Stages of Drug Alcohol Rehab-How It Works
