All drugs–nicotine, cocaine, marijuana and others–affect the brain’s “reward” circuit, which is part of the limbic system. This area of the brain affects instinct and mood. Drugs target this system, which causes large amounts of dopamine—a brain chemical that helps regulate emotions and feelings of pleasure—to flood the brain. This flood of dopamine is what causes a “high.” It’s one of the main causes of drug addiction.

It is important to find an alcohol rehab program that fits well with your personal beliefs. If you have strong religious beliefs, you can look for a program that shares your spiritual views. If you believe in the mind-body connection, a holistic program might be best for you. If you love the outdoors and physical activity for example, you may choose a program that includes outdoor and adventure therapies as part of its offerings.

With opiate abuse (heroin, morphine, OxyContin, Vicodin), withdrawal symptoms usually start within a matter of hours and last for several days. With stimulants like cocaine or methamphetamine, withdrawal may be more extensive, with cravings, depression, and anxiety lasting for several months. Withdrawal from prescription medications, such as sedatives in the benzodiazepine family (Valium, Xanax, Ativan) may require a drug taper lasting a number of weeks to clear the chemical safely from your system.
Alcohol abuse and addiction doesn’t just affect the person drinking—it affects their families and loved ones, too. Watching a family member struggle with a drinking problem can be as heartbreakingly painful as it is frustrating. But while you can’t do the hard work of overcoming addiction for your loved one, your love and support can play a crucial part in their long-term recovery.
A growing literature is demonstrating the importance of emotion regulation in the treatment of substance abuse. Considering that nicotine and other psychoactive substances such as cocaine activate similar psycho-pharmacological pathways,[44] an emotion regulation approach may be applicable to a wide array of substance abuse. Proposed models of affect-driven tobacco use have focused on negative reinforcement as the primary driving force for addiction; according to such theories, tobacco is used because it helps one escape from the undesirable effects of nicotine withdrawal or other negative moods.[45] Acceptance and commitment therapy (ACT), is showing evidence that it is effective in treating substance abuse, including the treatment of poly-substance abuse and cigarette smoking.[46][47] Mindfulness programs that encourage patients to be aware of their own experiences in the present moment and of emotions that arise from thoughts, appear to prevent impulsive/compulsive responses.[45][48] Research also indicates that mindfulness programs can reduce the consumption of substances such as alcohol, cocaine, amphetamines, marijuana, cigarettes and opiates.[48][49][50]
This is an ongoing debate in the medical community, but it is generally agreed that there is no one cause for the development of addiction. According to the National Institute on Drug Abuse, contributing factors may include a genetic predisposition to develop addictive tendencies, an environment that is permissive of drug abuse, access to illicit substances, and certain developmental issues. The existence of a Dual Diagnosis is one of the biggest risk factors for the development of addiction. Heroin Withdrawal | First Week In
