Key Findings

  • More respondents had used methamphetamine than had used heroin in the past three months (78% versus 72%) and in the past week (84% versus 78%). However, high frequency use of heroin (5-7 days in the past week) was more common than high frequency use of methamphetamine (59% versus 49%).
  • The majority (82%) of people who reported using heroin as their main drug were interested in reducing or stopping their opioid use.
  • About half (48%) of people who reported using methamphetamine as their main drug were interested in reducing or stopping their stimulant use.
  • Interest in treatment for hepatitis C (HCV) was high. About two thirds (68%) of those diagnosed with HCV were interested in HCV treatment among those who remained untreated.
  • Naloxone ownership has increased substantially among people who use opioids with 79% of respondents in King County and 78% outside of King County reporting they had owned a naloxone kit in the last 3 months, compared to 47% and 24% respectively in 2015.

Survey Overview

Since 2015, the University of Washington’s Alcohol & Drug Abuse Institute (ADAI) has collaborated with Public Health-Seattle & King County (PHSKC) and the statewide network of syringe services programs (SSP) to conduct the biennial WA State Syringe Exchange Health Survey to profile health behaviors and health care needs, access, and preferences of people who inject drugs (PWID) in WA State (see past survey results here: 2017 report, 2015 report).

In 2019 there were over 30 fixed site and/or mobile outreach SSPs operating in WA State through local health departments, community-based organizations, grassroots volunteer groups, or tribal entities. A complete list can be found here (WA State Dept of Health). A description of SSP operational models in WA State can be found here: Overview of Syringe Exchange Programs in WA State.

Survey respondents by zip code and ssp location (map with dots showing locations)

SSP staff and volunteers administer the voluntary, face-to-face questionnaire to individuals who come in for syringe exchange services.

The survey explores topics such as:

  • Client demographics.
  • Drug use and injection practices.
  • Utilization of syringe exchange and other health care services.
  • Prevalence of opioid overdose, overdose risks, and naloxone.
  • Prevalence of acute physical and psychiatric consequences of methamphetamine use.
  • Interest in reducing or stopping drug use.
  • Interest in specific services to help reduce or stop drug use. 

PHSKC uses a slightly modified version of the survey at its SSP sites to accommodate data needs particular to King County; therefore, some data presented do not include responses from King County.

Twenty-one organizations participated in the project and collectively completed surveys from 1,269 syringe services program participants across 23 counties.

Survey Results

Demographics of respondents

Respondents were majority male, with a substantial minority female and 1% identifying as transgender or other (Table below). Across a broad range of ages, the mean age was 36 years with a median age of 38 (Figure below). Most respondents self-identified as White with the proportion of other race/ethnicity categories varying by county. A disproportionately high percentage self-identified as American Indian/Alaska Native, 11% compared to 2% of the population in Washington State (Office of Financial Management, 2019). This is notable given that in Washington State, American Indians/Alaska Natives have a significantly elevated rate of fatal drug overdoses compared to other race/ethnicity groups.

Two thirds of respondents (69%) reported having unstable or no housing at all and over half of non-King County respondents (57%) had no legal monthly income. Over a third of respondents had been incarcerated in the past 12 months; interruptions in opioid tolerance caused by incarceration are a known risk for overdose.

Substance use patterns

Respondents were asked to list any use of a substance in the past three months and to identify which drug or drug combination was their “main” drug as they defined it. Any use of methamphetamine and/or heroin was reported by a majority of respondents (Table below). Almost a third (31%) reported using methadone or buprenorphine, followed by alcohol (29%), which was included for the first time in the 2019 survey. A smaller proportion reported using fentanyl (by itself or mixed in something), benzodiazepines, other opiate medications (the common term opiate used as an equivalent to opioid) and cocaine in its different forms or in combination with heroin.

While a slightly higher proportion reported any methamphetamine use in the past three months (84%) than any heroin use (78%), a much higher percentage identified heroin as their main drug (57%) compared to methamphetamine (26%). Use of methamphetamine and heroin combined (i.e., “goofball”) was also common.

Table: Substance use in past 3 months and "main drug". Meth by itself: 84%. Heroin by itself: 78%. Meth and heroin together: 46%. Methadone or buprenorphine: 31%. Alcohol 29%. Fentanyl: 18%. Benzos: 17%. Other opiate medications: 11%. Crack cocaine: 10%. Powder cocaine: 10%. Cocaine and heroin together: 7%.

Although surveying at SSPs specifically targets PWID (97% had injected a drug in the past three months), a sizable percentage reported also smoking drugs. A slightly higher percentage reported smoking methamphetamine than injecting it, 79% versus 73% respectively. While virtually all those who had used heroin did so by injection, half had also smoked it, a notable change from a decade ago when smoking heroin was uncommon in Washington State.

In this survey, 18% reported any use of fentanyl, by itself or believed to be mixed in with another drug, in the prior 3 months, with only one person reporting it as their main drug. However, the situation with fentanyl is unclear in Washington State in terms of the prevalence, appearance, sources, and which specific fentanyl compounds are involved. The most common appearance of fentanyl reported was “mixed with heroin or meth(amphetamine),” which contrasts with the relatively high prevalence of fentanyl in bogus pharmaceutical pills in some regions and police evidence testing results from the Washington State Patrol. Conflicting information likely reflects a wide range of community perceptions and differing perspectives provided by numerous data sources.

The figure below compares drug use across time periods. Methamphetamine use in the prior week was reported by 78% of respondents, with nearly half (49%) of all respondents using 5-7 days in past week. Conversely, a slightly smaller proportion (72%) reported any heroin use in the past week yet a higher proportion (59%) used heroin 5-7 days in the past week. Daily or near-daily use is more common for heroin than methamphetamine given heroin’s shorter-acting effects and its rapid onset of physical dependence.

Graph: Drugs used in different time frames.

Polysubstance use was reported by the vast majority of participants. The table below shows the variety of substances used in the past week by either heroin or methamphetamine as main drug. Past week use of a drug other than the “main” drug was nearly twice as likely among those whose main drug was heroin (91%) than those whose main drug was methamphetamine (48%). This pattern corresponds to long term trends for heroin and methamphetamine seen in multiple data sources for Washington State including fatal drug overdose data that indicate most heroin overdose deaths involve other substances compared to only about half of methamphetamine-related overdose deaths (data available at ADAI Interactive Drug Data).

Table: Polysubstance use in past week by main drug. Described in previous paragraph.

Looking specifically at use of both opioids and stimulants in the past week, the figure below shows that most main heroin users had also used stimulants (methamphetamine and/or cocaine), yet, conversely, most main methamphetamine users had not used opioids. In 2018 ADAI conducted qualitative interviews with SSP participants to explore motivations and patterns of concurrent methamphetamine and opioid use and produced this summary report: 2018 Qualitative Interviews with Syringe Exchange Participants.

Pie charts: Past week stimulant use among main heroin (n-725): 81% used stimulants. Past week opioid use among main methamphetamine: 31% used opioids.
Syringe exchange utilization and injection practices

On the day they were surveyed, two-thirds reported they were exchanging syringes for other people (i.e., “secondary exchange”) as well as themselves and for an average of two additional people (Table below). The majority also reported using an SSP more than once in the past month, with an average of three times per month. Frequency of SSP utilization is closely tied to the number of hours and days each SSP can operate and, along with rates of secondary exchange, indicate the potential reach of SSPs into the drug use and social networks of those individuals who access services in person.

Table: Utilization of syringe service programs. Described above.

The median age of first injecting any drug was 23, with over half (59%) injecting for the first time before the age of 26 (Figure below).

Bar chart: age at first injection. 20% under 18, 39% 18-25, 29% 26-35, 11% 36-50, 1% 51+

The majority (78%) of people
injected 5-7 days in the last week with most injecting every day (Table below).
The average number of injections per day was 3.5, and 65% of respondents
reported that they typically use a syringe only once before disposing of it. While
one-time use of syringes is promoted at SSPs to minimize vein damage and skin
infections, one-time use may be difficult in areas where inadequate funding for
SSPs limits syringe supply or the number of days an SSP can provide services
each week.  

Eighty-five percent (85%) reported that they had not shared a syringe with another person in the last three months, and 60% reported that they had not shared other drug injection materials (e.g., cottons, cookers, water) in the last three months. Because sharing other injection materials can transmit infectious diseases like HIV and hepatitis C, all SSPs provide these materials in addition to exchanging used syringes for new syringes.

Table: Drug injection practices. Described above.
Health care needs and utilization

Nearly half (42%) reported having an abscess or skin infection in the last 12 months while other drug injection-related conditions (e.g., blood clots, blood infections, endocarditis) and sexually transmitted infections were less common (Table below). Few women reported being pregnant in the prior year.

Table: Health conditions, last 12 months. Described above.

The same proportion (93%) of respondents had ever been tested for HIV or hepatitis C virus (HCV), over half within the last year (Figure below).

Bar chart: HIV and Hepatitis C testing. Described above.

Only 28% of those diagnosed with HCV had completed, or at least started, HCV treatment (Figure below). Among people who had been diagnosed with but not treated for HCV, the majority (68%) were interested in hepatitis C treatment, which is important given that most respondents have Medicaid coverage that, as of 2019, pays for HCV treatment.

Figure: Hepatitis C diagnosis and treatment. Described above.

Substantial majorities expressed some level of concern about either depression or anxiety (Figure below). Twenty percent (20%) of respondents said they were “very concerned” about both depression and anxiety while a similar proportion (19%) had no concerns at all about either.

Figure: Mental health: How concerned are you about anxiety (26% not at all, 37% somewhat, 36% very), depression (34% not at all, 40% somewhat, 26% very)

Only 8% reported having no health care coverage, with most reporting some form of public insurance, most commonly Medicaid (Figure below).

Pie chart: Types of health care coverage. Medicaid 81%, Medicare 7%, Private 5%, Tribal health 2%, Veteran's affairs 1%, no insurance 8%

Most respondents accessed medical care in the past 12 months through a number of settings such as medical offices/clinics, syringe exchanges, jails and mobile medical clinics (Figure below). Nearly a quarter (23%) of respondents had been admitted to a hospital, and just over half (56%) had used an emergency department, with about one third reporting multiple visits in the last 12 months (Figures below).

Opioid overdose and acute consequences of methamphetamine use

Among people who had used opioids, 22% had experienced at least one opioid overdose (defined in the survey as “when breathing slows down or stops and a person can’t be woken up”) in the past 12 months (Figure below).

Pie chart: Number of opioid overdoses had in past 12 months among people who used opioids. Described above.

Over half (59%) of all respondents had witnessed at least one opioid overdose (Figure below). Many survey respondents had experienced or had witnessed multiple opioid overdoses.

Number of opioid overdoses witnessed in past 12 months among all respondents: none: 41%, 1 or more: 59%

About one-third (33%) reported they injected drugs alone most or all of the time, which increases the risk that an overdose could be fatal because bystanders are not available to intervene (Figure below).

Figure: How often do you inject alone? 27% never, 40% some of the time, 21% most of the time, 12% always

The substantial majority of those who used opioids reported owning a naloxone kit in the last three months (Figure below). Distribution of free naloxone kits through SSPs across the state has steadily increased over the past four years, most notably outside King County since 2016 with the implementation of a five-year federal SAMHSA grant1 to scale-up naloxone distribution in high-need areas of the state. At the time of writing, all SSPs in WA State distribute naloxone to participants at no cost and collectively represent the largest channel of naloxone distribution to laypersons in the state.

Bar chart: Owned a naloxone kit in the last 3 months, among people who used opioids in past 3 months. 2015: 47% in King County, 24% not in King County. 2017: 66% King County, 59% not King County. 2019: 79% King County, 78% not King County.

Among people who had used methamphetamine by itself or mixed with heroin (i.e., “goofball”) in the last three months, a quarter (25%) reported acute psychiatric conditions related to methamphetamine use in that time period and 15% reported acute physical conditions (Figure below). A small percentage (9%) reported they had been to the emergency room for acute psychiatric or physiological symptoms related to methamphetamine2.

  2. Overdose related to methamphetamine has been challenging to document in these SSP surveys as the clinical presentation of potentially fatal symptoms is more complex and variable than in opioid overdoses. The 2017 survey asked about experience with “overamping” (defined in the survey as an event that “usually looks like a heart attack, stroke, seizure, intense overheating or really extreme sudden psychosis”) but that definition proved confusing and imprecise for some respondents. The 2019 survey continued to refine this question by focusing on specific symptoms.
Substance use disorder treatment

Over half (60%) of people who reported heroin as their main drug reported receiving some kind of substance use treatment, most often buprenorphine and methadone, in the prior year (Figure below).

Bar chart: Drug treatment received in last 12 months among people who reported main drug heroin. Any treatment 60%, Buprenorphine 36%, Methadone 19%, Outpatient 15%, Detox 12%, 12-step 10%, Inpatient 8%, Naltrexone 2%, other 1%

However, only one in four people (25%) reporting methamphetamine as their main drug reported any type of substance use treatment in the past 12 months (Figure below). This may reflect the fact that there are not yet treatment medications proven effective for methamphetamine and/or the fact detailed below that people who use methamphetamine reported less interest in stopping or reducing their stimulant use. A minority of people whose main drug was methamphetamine also reported use of medications to treat opioid use disorder.

Bar chart: Drug treatment received in the last 12 months among people who reported main drug methamphetamine. Any treatment 25%, Outpatient 11%, buprenorphine 8%, methadone 5%, detox 5%, inpatient 5%, 12-step 3%, other 0%
Interest in reducing drug use and related services

Of those whose main was drug was heroin and who had used heroin in the past week, 82% said they were “very” or “somewhat” interested in reducing or stopping their opioid use, and these respondents were most interested in treatment medications for opioid use disorder (Figures below). Other services preferred to help reduce opioid use ranged from specialty addiction treatment services (e.g., detox, inpatient and outpatient treatment), to individual counseling, help navigating services, and mental health medications. “Other” types of help included housing, adequate pain treatment, and employment or education opportunities.

Figure: how interested are you in reducing or stopping your opioid use (among main drug heroin, not in treatment, with past week heroin use, n=514). 56% very interested, 26% somewhat, 8% not sure, 10% not interested

Medications 70%, detox 54%, 1:1 counseling 47%, help navigating services 44%, inpatient 38%, outpatient 37%, mental health medications 30%, other 9%, don't want help 2%

Among main methamphetamine users, however, only 48% were very or somewhat interested in reducing their stimulant use, although there was similar interest in a range of services, including interest in any medications that might help reduce stimulant use, counseling, care navigation and other services (Figures below)1.

Figure: How interested are you in reducing or stopping your stimulant use (among main drug meth, not in treatment, past week meth use, n=281). 24% very, 24% somewhat, 18% not sure, 33% not interested
