Mental health problems. If you suffer from a mental health problem, whether or not it has been diagnosed, and whether or not you take medication for it, you are at higher risk for addiction. Mental health problems include anxiety, attention-deficit/hyperactivity disorder (ADHD), depression, bipolar personality disorder, and post-traumatic stress disorder (PTSD), to name a few.
In addition to CREB, it is hypothesized that stress mechanisms play a role in dependence. Koob and Kreek have hypothesized that during drug use, CRF activates the hypothalamic–pituitary–adrenal axis (HPA axis) and other stress systems in the extended amygdala. This activation influences the dysregulated emotional state associated with psychological dependence. They found that as drug use escalates, so does the presence of CRF in human cerebrospinal fluid. In rat models, the separate use of CRF inhibitors and CRF receptor antagonists both decreased self-administration of the drug of study. Other studies in this review showed dysregulation of other neuropeptides that affect the HPA axis, including enkephalin which is an endogenous opioid peptide that regulates pain. It also appears that µ-opioid receptors, which enkephalin acts upon, is influential in the reward system and can regulate the expression of stress hormones.[18]

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
