The signs of addiction vary from drug to drug. Some drugs take longer to produce noticeable symptoms. In some cases, the symptoms blend in with normal behaviors, making it difficult to tell that the person is addicted. Common signs of addiction include needle marks on the arms of people who inject drugs and constant nose sores on people who snort drugs.
Different rehabs are based upon different philosophies, and this can mean the enhancement of addiction treatment with distinct specialized services. For example, a religious rehab may include worship services or religion classes and other offerings that enhance the spiritual side of recovery while a holistic alcohol rehab may include yoga, meditation, acupuncture and other alternative methods of treatment.
Many physicians believe no effective treatment is available for alcoholism; therefore, these physicians do not refer their patients for treatment. However, more than 13 studies representing more than 4000 patients demonstrate that brief interventions make a difference. Most of the patients in these studies drank heavily but did not yet have a problem with alcohol.
Addiction can be either behavioral or substance related. An intense feeling of emotional need or physical craving characterizes them both. Both types of addiction carry a number of other similarities, but behavioral addiction does not possess the same physical symptoms that accompany drug addiction. Experts disagree on the similarities and differences between the symptoms and consequences of the types of addictions.

NOTE: This fact sheet discusses research findings on effective treatment approaches for drug abuse and addiction. If you’re seeking treatment, you can call the Substance Abuse and Mental Health Services Administration's (SAMHSA's) National Helpline at 1-800-662-HELP (1-800-662-4357) or go to www.findtreatment.samhsa.gov for information on hotlines, counseling services, or treatment options in your state. 
Once you complete the rehabilitation stage, you will begin to gradually acclimate yourself to daily life. It’s important to give yourself time to ease back into the swing of things. Attending support groups, such as Alcoholics Anonymous or Al-Anon, that offer encouragement and engagement with others in recovery, group leaders and sponsors can be a positive way to make a lifestyle change and maintain sobriety.
In-patient residential treatment for alcohol abuse is usually quite expensive without proper insurance. Most American programs follow a traditional 28–30 day program length. The length is based solely upon providers' experience. During the 1940's, clients stayed about one week to get over the physical changes, another week to understand the program, and another week or two to become stable.[18] 70% to 80% of American residential alcohol treatment programs provide 12-step support services. These include, but are not limited to AA, NA, CA, Al-Anon[18] One recent study suggests the importance of family participation in residential treatment patient retention, finding "increased program completion rate for those with a family member or significant other involved in a seven-day family program."[19]
Stimulants, such as tobacco, cocaine or prescription amphetamines, stimulate the brain and nervous system, causing increased alertness. Depressants, such as barbiturates and benzodiazepines, slow activity in the brain and nervous system, causing relaxation. Hallucinogens, such as LSD and PCP, drastically disrupt the way the brain and nervous system communicate, causing hallucinations. Rehab: Last Week Tonight with John Oliver (HBO)
