Steroid, ecstasy, heroin, and other drugs are dangerous to health. People who take these substances suffer physical, emotional, behavioural, and relational changes. Besides, regular consumption of these drugs lead the users to develop endurance, in which case they will need to choose the dose in higher quantity for experiencing similar effects. This so-called tolerance can develop into habitual addiction since it tends to affect the chemistry of the brain. As such, not receiving treatment may lead to fatal consequences.
Drug rehabilitation (often drug rehab or just rehab) is a term for the processes of medical or psychotherapeutic treatment, for dependency on psychoactive substances such as alcohol, prescription drugs, and street drugs such as cocaine, heroin or amphetamines. The general intent is to enable the patient to cease substance abuse, in order to avoid the psychological, legal, financial, social, and physical consequences that can be caused, especially by extreme abuse. Treatment includes medication for depression or other disorders, counseling by experts and sharing of experience with other addicts. Some rehab centers include meditation and spiritual wisdom in the treatment process.
