(Worldwide Treatment Need vs Availability) "Expressed in monetary terms, some US$ 200 billion-250 billion (0.3-0.4 per cent of global GDP) would be needed to cover all costs related to drug treatment worldwide. In reality, the actual amounts spent on treatment for drug abuse are far lower — and less than one in five persons who needs such treatment actually receives it."

"Illicit drug use disorder is defined as meeting DSM-IV criteria for either dependence or abuse for one or more of the following illicit drugs: marijuana, cocaine, heroin, hallucinogens, inhalants, methamphetamine, or prescription psychotherapeutic drugs that were misused (i.e., pain relievers, tranquilizers, stimulants, and sedatives). There are seven possible dependence criteria for specific illicit drugs:

"The number of clients in treatment on the survey reference date increased by 21 percent from 2005 to 2015, from 1,081,049 in 2005 to 1,305,647 in 2015.

"Facility Operation
"Table 3.1 and Figure 4. Within the categories of facility operation, the proportions of clients in treatment demonstrated some gradual changes between 2005 and 2015.

"Government agencies and professional societies,* including the American Society of Addiction Medicine, have recommended against using AAROD in clinical settings (9). There is insufficient knowledge regarding how widely AAROD is used in the United States and the frequency of AAROD-associated adverse events in community practice settings. At least seven deaths occurred following AAROD among 2,350 procedures performed in one practice during 1995–1999.†

Treatment Facilities in the US Offering Programs or Groups for Women and Other Specific Client Types, 2012. "Facilities were asked about the provision of treatment programs or groups specially designed for specific client types. Overall, 82 percent of facilities offered at least one special program or group to serve a specific client type."

"• Marijuana/hashish was reported as the primary substance of abuse by 14 percent of TEDS admissions aged 12 and older in 2015 [Table 1.1b].

"• The average age at admission for primary marijuana/hashish admissions was 26 years [Table 2.1b]. Thirty-one percent of marijuana/hashish admissions were under age 20 (vs. 7 percent of all admissions combined), and primary marijuana/hashish abuse accounted for 78 percent of admissions aged 12 to 14 and 75 percent of admissions aged 15 to 17 years [Table 2.1c].

"During the course of treatment, many treatment seekers stopped using the drugs that they reported using at entry to the study. Lower rates of drug use were recorded at each follow-up. Furthermore, those that continued to use tended to use less. Most of the changes observed occurred by first follow-up. For most forms of drug use, no particular treatment modality was more associated with cessation than any other and the route into treatment (CJS or non-CJS) did not influence drug-use outcomes.
