<OpenstaxParagraph>
	Addiction is often viewed as a chronic disease (<a href="#CNX_Psych_16_04_DrugSurvey">Figure 16.18</a>). The choice to use a substance is initially voluntary; however, because chronic substance use can permanently alter the neural structure in the prefrontal cortex, an area of the brain associated with decision-making and judgment, a person becomes driven to use drugs and/or alcohol (Muñoz-Cuevas, Athilingam, Piscopo, &amp; Wilbrecht, 2013). This helps explain why relapse rates tend to be high. About 40%–60% of individuals <OpenstaxTerm>relapse</OpenstaxTerm>, which means they return to abusing drugs and/or alcohol after a period of improvement (National Institute on Drug Abuse [NIDA], 2008).

Note that the following percentages are estimates. According to this chart, 10 percent of people in the age range of 12–17 use illicit drugs, compared to 22 percent usage in the age range of 18–25, and 7 percent usage in the age range of 26 and older. 7.5 percent of people in the age range of 12–17 use marijuana, compared to 18 percent usage in the age range of 18–25, and 5 percent usage in the age range of 26 and older. 3 percent of people in the age range of 12–17 use psychotherapeutics, compared to 6 percent usage in the age range of 18–25, and 2.5 percent usage in the age range of 26 and older. 1 percent of people in the age range of 12–17 use inhalants. This number steadily drops off to 0 percent in the 26 and older age group. 1 percent of people in the age range of 12–17 use hallucinogens, compared to 2.5 percent usage in the age range of 18–25, and almost 0 percent usage in the age range of 26 and older.

<OpenstaxParagraph>
	The goal of substance-related treatment is to help a person with an addiction stop compulsive drug-seeking behaviors (NIDA, 2012). This means a person with addiction will need long-term treatment, similar to a person battling a chronic physical disease such as hypertension or diabetes. Treatment usually includes behavioral therapy and/or medication, depending on the individual (NIDA, 2012). Specialized therapies have also been developed for specific types of substance-related disorders, including alcohol, cocaine, and opioids (McGovern &amp; Carroll, 2003). Substance-related treatment is considered much more cost-effective than incarceration or not treating those with addictions (NIDA, 2012) (<a href="#CNX_Psych_16_04_Crack">Figure 16.19</a>).
