Addiction is a condition that affects the brain and behaviour. The most common of addiction is drug abuse. Drug abuse is defined as the continued use of a substance in an increasing amount over a period of time. The person who abuses drugs is known as a substance abuser. The most serious and dangerous form of drug abuse is heroin or cocaine abuse. Alcoholism and tobacco addiction are the two most deadly forms. Each has its own set of symptoms and signs and requires the same kind of treatment. The first stage of any substance abuse treatment is to get the person to admit that he or she has a problem. It may be because they don’t feel they have a need for a drug or alcohol, or it may be because they just have poor self-control. In these cases, the addict will need to overcome his or her fear of admitting that they have a problem. The addict may need to go through therapy or group meetings with a therapist or group of people. This will help them learn how to acknowledge their problems and face them. The individual’s fear of facing these issues can be overcome by doing the right things at the right time. Another type of drug or alcohol that may be abused is nicotine or caffeine. The individual may begin by smoking a cigarette or chewing on gum. Eventually, they can take it further and start to use marijuana or other drugs to get the same feelings. The addict may be addicted to some kind of drug or substance because they use it once, but when they stop, they usually return to their old habits. For this reason, the individual needs to know what will trigger their addiction if they want to stop. This is why it is so important for addicts to undergo a program that teaches them how to recognize when they are in a relapse and how to overcome the temptation to use that substance again.
