There are not very many studies that have examined how often<unk>  occurs or how many people are dependent on multiple substances. However, according to a study that analyzed the results from the National Epidemiological Survey on Alcohol and Related Conditions, approximately 215.5 out of a total of 43,093 individuals in the United States (0.5%) met the requirements for<unk>  use disorder. Another study suggested that the number of new cases of<unk>  has been going up. This idea was supported by a study that took place in Munich, Germany. A group of researchers chose to look at responses to a survey using the M-Composite International Diagnostic Interview (M-CIDI). The M-CIDI is a version of the Composite International Diagnostic Interview (CIDI). The researchers collected data from 3,021 participants, all between the ages of 14 and 24, to estimate the prevalence, or total number of cases, of substance use and of<unk>  use/dependence. The results of this study indicated that of the 17.3% who said that they regularly used substances, 40% said that they used more than one substance, but 3.9% specifically reported using three or more substances, indicating that there is a lot of overlap in the use of different substances. The researchers compared their results to earlier German studies and found that substance dependence seems to be increasing, at least in Germany. Gender differences Women and men differ in various ways when it comes to addictions. Research has shown that women are more likely to be<unk>  dependent. It has been noted that a larger percentage of women use licit (legal) substances such as tranquilizers, sedatives, and stimulants. On the other hand, men are more likely to use illicit (illegal) substances such as cocaine, methamphetamine, and other illicit substances. Research suggests that women addicts more frequently have a family history of substance use. When asked to describe their onset of addictions, women more frequently describe their addiction as sudden where as men describe them as gradual. Females have a higher percentage of fatty tissues and a lower percentage of body water than men. Therefore, women absorb substances more slowly. This means these substances are at a higher concentration in a woman’s bloodstream. Female addicts are known to be at greater risk for fatty liver disease, hypertension, anemia, and other disorders.
