Drug Abuse Trends in the Seattle/King County Area: 2010 Caleb Banta-Green1, T. Ron Jackson2, Steve Freng3, Michael Hanrahan4, Geoff Miller8, Steve Reid5, John Ohta6, Mary Taylor7, Richard Harruff8, and David Albert9 Abstract Cocaine continues to be a major drug of abuse and contributor to deaths. Treatment admissions and deaths both declined somewhat in 2010. Levamisole (a potentially life threatening contaminant) was present in two-thirds of cocaine seized by police in King County in 2010 and was present in both crack and powder cocaine. Fatal heroin overdoses remained low at 50 in 2010, the same number as in 2009 and substantially lower than the 144 heroin involved overdoses in 1998. The number of people dying in King County from prescription-type opiate overdoses declined for the first time in a decade. In 2010 in King County, 130 fatal overdoses involved prescription type opiates (most commonly methadone and oxycodone), a decline from 161 deaths in 2009 and the first decline since 1999. Newly available prescription sales data for Washington State through 2010 indicate that sales began leveling off over the last three to four years for several common, potent pain medicines including morphine, methadone, and oxycodone after steady increases in sales since 1997. These same data indicate a seven-fold increase in prescribing of buprenorphine by King County providers (mostly for the treatment of opiate addiction) with an estimate of at least 2,353 annual addictioin treatment spaces used in 2010. While the decline in prescription-type opiate deaths is positive, there are reasons for concern. Treatment admissions for those addicted to prescription type opiates continue to increase and the majority are young adults ages 18 to 29. The number of young adults in treatment programs for heroin is up 74% from 1999 to 2010. Heroin purity is low right now, which may be contributing to the lower level of fatal heroin overdoses. Increased education and vigilance on the part of the public will be important to prevent future addiction and overdoses. Information on opiate medication and heroin safety and overdose prevention is available at www.stopoverdose.org and http://www.doh.wa.gov/hsqa/takeasdirected/default.htm . Methamphetamine treatment admissions and deaths have held steady since 2005. While most methamphetamine appears to originate in Mexico, local, small scale production continues. Marijuana remains the most common drug among youth admitted to treatment. Adult treatment admissions declined slightly in 2010 though they have tripled since 1999, with increases mostly among males, African Americans and Hispanics. “Bath salts”, usually MDPV/Mephedrone, are present at apparently low levels and serious adverse consequences have been reported locally. Synthetic cannabinoid agonists (e.g. Spice/K2) are being used locally, mostly in an exploratory way by youth or by those who are required to get regular drug testing due to court or treatment involvement, it is reportedly less desirable than marijuana. MDMA use and availability persists and there was a substantial decrease in the adulterant BZP in 2010. New HIV infections remain fairly low among injection drug users with 4% of new infections in this exposure group from 2008 to 2010 and 7% of new infections among those with the dual exposure of IDU and being men who have sex with men. More than four million clean syringes were distributed to injection drug users in King County in 2010. 1The author is affiliated with the Alcohol and Drug Abuse Institute, University of Washington. 2 The author is affiliated with Evergreen Treatment Services. 3The author is affiliated with the Northwest High Intensity Drug Trafficking Area. 4The author is affiliated HIV/AIDS Epidemiology, Public Health – Seattle and King County. 5The author is affiliated with the Washington State Patrol Crime Laboratory. 6The author is affiliated with the Ryther Child Center and the University District Youth Center. 7The author is affiliated with the King County Drug Courts. 8The author is affiliated with the Seattle and King County Medical Examiner’s Office, Public Health. 9The author is affiliated with the Division of Behavioral Health and Recovery, Washington State Department of Social and Health Services. 1 INTRODUCTION Data Sources The primary sources of information used in this report are listed below: • Drug trafficking data were obtained from the Drug Enforcement Administration (DEA). Seattle Field Division Quarterly Trends in the Traffic Reports. Domestic Monitoring Program (DMP) heroin purchase data (edited ver- sions) were also utilized, and data specific to Seattle were extracted and analyzed. Data were also obtained from the Threat Assessment Report produced by the Northwest High Intensity Drug Trafficking Area (NW HIDTA) program, which included survey data from local law enforcement throughout the State of Washington. • Opioid sales data, DEA ARCOS, were obtained directly from national DEA through 2010. Sales data are in grams of active ingredient. For buprenorphine a conversion to estimated dosage units was made based upon an average dose of 16mg/day among Medicaid patients (nothing about prescribing among private/self- pay is known and these are likely to represent 90% of buprenorphine treatment). Note that buprenorphine is occasionally prescribed for pain management, but the predominate indication is medication assisted drug treatment for opioid addicts. An additional estimate was made of “annual treatment” slots, that simply divided the total number of estimated dosage units by 365 to provide an estimate (and sense of scale) of how many patients could be receiving buprenorphine treatment if they received it on every day in the calendar year. King County data were approximated by combining data from the 3 digit zip code regions beginning with 980 and 981. (Exhibit 1) • Fatal drug overdose data were obtained from the King County Medical Examiner (KCME), Public Health – Seattle & King County (PHSKC). The other opiates category indicates pharmaceutical opioids, including pharmaceutical morphine where noted (oxycodone, hydrocodone, methadone, and other opioids); however, codeine is excluded. The heroin/opiate category includes heroin, morphine (unless noted to be pharmaceutical), and cases where there was an indication that the death was “heroin related” in the KCME database. (Exhibit 2) • Data on seized drug samples submitted for analysis were obtained from the National Forensic Laboratory Information System (NFLIS), DEA. Drug testing results for local, State and Federal law enforcement seizures in King County were reported. A Washington State Patrol Crime Laboratory chemist attended the local CEWG meeting and provided qualitative impressions of drug seizure evidence they tested. These analytical tests are the basis of NFLIS data. The laboratory also created a dataset for cocaine in the Fall of 2010 to document the details of levamisole involved cocaine cases. (Exhibit 3) • Drug treatment data were provided by Washington State Department of Social and Health Services (DSHS), Division of Behavioral Health and Recovery, Treatment Report and Generation Tool (TARGET), from 1999 through 2010. Treatment modalities included outpatient, intensive inpatient, recovery house, long- term residential, and opiate substitution admissions. Department of Corrections 2 and private-pay admissions for opiate substitution were included. Opioid sales data for buprenorphine, described above, are also a proxy for opioid addiction treatment. (Exhibit 4) • Washington State Poison Center call data for exposure calls from 2004 to 2010 for calls originating in King County were provided. (Exhibit 5) • Washington State Healthy Youth Survey data from 2010 for a random sample of King County schools are reported. The total number of surveys included in analyses was 4,015. • Data on infectious diseases related to drug use and injection drug use, including the human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS), were provided by PHSKC. Data on HIV cases (including exposure related to injection drug use) in Seattle/King County (1982 through 2010) were obtained from the “HIV/AIDS Epidemiology Report.” Data for the number of syringes exchanged/distributed were also provided by PHSKC. (Exhibits 6 and 7) DRUG ABUSE PATTERNS AND TRENDS Cocaine NFLIS tests positive for cocaine decreased for the fourth year in a row. According to law enforcement and prosecutors this is mostly due to policy changes regarding obtaining evidence and the amount of cocaine needed for certain types of prosecutions. Local police report cocaine is readily available in Seattle. Growing concerns about levamisole (an adulterant that can lead to serious immune reactions) nationally led to questions about the presence of levamisole locally. In the Fall of 2010, information about levamisole in cocaine seized by law enforcement in King County was systematically documented. In the past, levamisole has been observed in cocaine samples, but not documented as the State crime lab only records illegal and controlled drugs. Of 47 cocaine samples, 65% tested positive for levamisole. Approximately three-quarters of the samples weighed less than 3 grams indicating relatively small samples that were likely for personal use. The presence of levamisole was consistent across forms (salt and base) and appearance (powder and chunky). Levamisole was also identified in residue from pipes indicating the hardiness of the compound. Cocaine treatment admissions have declined for
