What people often referred to as drug addiction is synonymous to the diagnosis of substance dependence. When a person shows either tolerance or withdrawal from the substance, the person shows physiological dependence on the substance. Tolerance is present when a person experiences less and less effect from the same dose of substance and needs greater and greater doses of a substance in order to achieve intoxication. Regarding people who smoke, 20 cigarettes would make a person who just recently began smoking get violently ill while people who have smoked cigarettes for years would have no problem with that amount. A person may not have enough awareness on the effects of the substance but can have high tolerance on it and may have a very high blood level of the substance . For example, people who are extremely tolerant to alcohol may have blood-alcohol levels far beyond those used in the legal meaning of intoxication but illustrate little signs of alcohol intoxication. The risk of tolerance varies greatly from one substance to the next. Cannabis and PCP show lower risks for tolerance while alcohol, opioids, stimulants, and nicotine have high risks for tolerance.
People who are physiologically dependent on substances often show severe withdrawal symptoms when they stop using the substances. Symptoms may be so severe that in order to prevent the symptoms from becoming overwhelming or dangerous, the substances must be withdrawn gradually . These people may take the substances to relieve or avoid withdrawal symptoms. For instance, a person dependent on alcohol may have a drink first thing in the morning to alleviate the withdrawal symptoms.
Physiological dependence (i.e., evidence of tolerance or withdrawal) is not required for a diagnosis of substance dependence, however. Despite the experience of significant social, occupational, psychological, or medical problems as a result of the use , the diagnosis may be given when a person compulsively uses a substance .
Most people who are dependent on a substance crave the substance and will do almost anything to get the substance (e.g., steal, lie, prostitute themselves) when the craving is strong. Obtaining and ingesting the substance may be the center of the lives of these people. The cycle of going back to the substance again and again will always happen despite having the attempt on cutting back or quitting the use of the substance.
It has always been a fact that drug addiction or drug dependence is bad and carries many negative consequences. The best move is to always stay away from it. However, if you happen to know someone who has failed to stay away from it, there is still a way to help that person lessen the bad effects of drug addiction.
