Biological factors that can affect a person's risk of addiction include their genes, stage of development, and even gender or ethnicity. Scientists estimate that genes, including the effects environmental factors have on a person's gene expression, called epigenetics, account for between 40 and 60 percent of a person's risk of addiction.27 Also, teens and people with mental disorders are at greater risk of drug use and addiction than others.28
Drug addiction is a chronic brain disease that causes powerful physical and psychological cravings for mind-altering substances, including illegal intoxicants like cocaine, heroin, methamphetamine, and PCP. Many people also become addicted to misused prescription drugs, or to chemical substances not manufactured for human consumption (inhalants), to party drugs (ecstasy), hallucinogens like LSD, or to marijuana, which despite its benign reputation is the most widely abused illicit drug.
In such cases, some rehabs offer outpatient services: the addict can go through the detox phase with medical help as and when required, and can then visit the facility for therapy sessions by appointment. Indeed it is often also possible to have phone therapy sessions if the addict cannot make it physically to the facility (this is often the case with professionals who travel a great deal and may not be in the country for an extended period).
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
