There are a few ways a person can take drugs, including injection, inhalation and ingestion. The effects of the drug on the body can depend on how the drug is delivered. For example, the injection of drugs directly into the bloodstream has an immediate impact, while ingestion has a delayed effect. But all misused drugs affect the brain. They cause large amounts of dopamine, a neurotransmitter that helps regulate our emotions, motivation and feelings of pleasure, to flood the brain and produce a “high.” Eventually, drugs can change how the brain works and interfere with a person’s ability to make choices, leading to intense cravings and compulsive drug use. Over time, this behavior can turn into a substance dependency, or drug addiction.
Even relatively moderate drug use poses dangers. Consider how a social drinker can become intoxicated, get behind the wheel of a car, and quickly turn a pleasurable activity into a tragedy that affects many lives. Occasional drug use, such as misusing an opioid to get high, can have similarly disastrous effects, including overdose, and dangerously impaired driving.
A program with principles that contradict the patient’s religious beliefs or personal values is unlikely to be effective. For instance, a patient who objects to spiritually-based recovery probably won’t be comfortable at a facility that places a strong emphasis on 12-step programming. When choosing a treatment facility, look for a program that meshes with the individual’s spiritual nature and cultural heritage.
When you have a child struggling with substance abuse, attempting to handle it on your own can be extremely overwhelming and can eventually become your first and only priority. It may also be difficult to take the first step because addressing the problem is disruptive of school and extracurricular activities.2 However, addiction is far more disruptive to your child's life in the end, and treatment can work. Taking the time now to get help can save your child's life.
Depending on your treatment priorities, you may also want to consider a facility that shares your philosophy. For instance, some people prefer faith-based rehabs if their religion is important to them. Others may choose to enroll in a holistic treatment center that utilizes alternative and complementary practices, such as acupuncture, meditation, and yoga. Regardless of the treatment program you choose, it’s important to confirm that it possesses the above-mentioned qualities.
Drug addiction is a chronic disease characterized by compulsive, or uncontrollable, drug seeking and use despite harmful consequences and changes in the brain, which can be long lasting. These changes in the brain can lead to the harmful behaviors seen in people who use drugs. Drug addiction is also a relapsing disease. Relapse is the return to drug use after an attempt to stop.

Nalmefene, an opiate antagonist that is similar in its chemical structure to naltrexone, is one of the most recent drugs being investigated for the treatment of alcoholism. Like naltrexone (sold as ReVia, Depade, or Vivitrol), nalmefene deprives the person struggling with substance use of the pleasurable feelings associated with drinking. But nalmefene is less toxic to the liver than naltrexone. As of 2013, nalmefene was still undergoing clinical trials through the U.S. National Institutes of Health before receiving FDA approval.
