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. People who have smoked cigarettes for years often smoke more than 20 cigarettes a day, when the same amount would have made them violently ill when they first began smoking. A person who is highly tolerant to a substance may have a very high blood level of the substance without being aware of any effects of the substance. For example, people who are very tolerant to alcohol may have blood-alcohol levels far above those used in the legal explanation of intoxication but show little signs of alcohol intoxication. From one substance to the next, the risk of tolerance varies. Alcohol, opioids, stimulants, and nicotine have high risks for tolerance whereas cannabis and PCP appear to have lower 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may be so severe that in order to prevent the symptoms from becoming overwhelming or dangerous, the substances must be withdrawn gradually . In order to relieve or avoid these withdrawal symptoms, these people may take the substances . For example, a person dependent on alcohol may have a drink first thing in the morning to alleviate the withdrawal symptoms.
However, a diagnosis of substance dependence does not requires physiological dependence (i.e., evidence of tolerance or withdrawal). The diagnosis can be given when a person compulsively uses a substance, despite experiencing significant social, occupational, psychological, or medical problems as a result of the use.
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. Their entire lives may revolve around obtaining and ingesting the substance. 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.
The bad image and the negative consequences has always been synonymous to substance dependence or drug addiction. Staying away from addictive substances will always be the smart move. 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. This is done through going in a drug rehab. In this kind of situation, how does drug rehab can able to help? Drug rehab offers different procedures that have a very high assurance to help one get out from the hells of drug addiction. One should not wait for situations to get worse and should start obtaining information from your local medical center regarding drug rehab.
Substance dependence is synonymous to a barrel of problems; one of the ways to get rid of these barrel of problems is by going through a drug rehab.
