Pulse Check: Trends in Drug Abuse November 2001

Methamphetamine: The Perception

How do Pulse Check sources perceive the methamphetamine problem in their communities, and have their perceptions changed? Only three sources in two cities (both western) consider methamphetamine the most widely used drug in their communities: the law enforcement source in Billings and the epidemiologic and nonmethadone sources in Honolulu. Additionally, nine sources in five cities (all western) consider methamphetamine the second most widely used drug: in Billings (the epidemiologic and non-methadone treatment sources), Denver (the non-methadone treatment source), Honolulu (the law enforcement source), Los Angeles (the non-methadone treatment source), and Sioux Falls (the law enforcement, epidemiologic, and methadone and non-methadone treatment sources). Since the last Pulse Check reporting period, no changes were reported in the perceptions of methamphetamine as the most or second most widely abused drug.

More sources report methamphetamine as contributing to the most serious consequences in their communities than report methamphetamine as the most widely used drug. Thirteen sources in four cities (Billings, Denver, Honolulu, and Sioux Falls) report methamphetamine as contributing to the most serious consequences. The Memphis law enforcement source is the only one to report methamphetamine as the drug contributing to the second most serious consequences. Again, since the last Pulse Check, no changes were reported in the perceptions of methamphetamine as the drug of abuse contributing to the most or second most serious consequences.

METHAMPHETAMINE: THE DRUG

How available is methamphetamine across the country? (Exhibit 1) Nearly two-thirds (25 of 42) of law enforcement, epidemiologic, and ethnographic sources report methamphetamine as somewhat or widely available in their communities, and availability varies widely by region. In the West, it considered widely available by nearly every respondent (in Billings, Denver, Los Angeles, Honolulu, and Seattle); in the Midwest, it ranges from not very available (in Chicago) to widely available; in the South, it ranges from not very to widely available; and in the Northeast, it is not very or not available, according to nearly every respondent.

*The epidemiologic and ethnographic sources in Columbia and El Paso did not provide this information.

Has methamphetamine availability changed? (Exhibit 2) Since the last reporting period, methamphetamine availability increased or remained stable according to all law enforcement, epidemiologic, and ethnographic respondents, with the exception of the law enforcement source in Philadelphia and the epidemiologic source in Boston, who report availability declines. Similar to the last Pulse Check, most increases occurred in the South, Midwest, and West, although the percentage of western sources reporting increases this reporting period is lower than the percentage reporting increases last period (50 versus 86 percent).

What type of methamphetamine is available? Locally produced methamphetamine is slightly more available than methamphetamine produced in Mexico, according to law enforcement, epidemiologic, and ethnographic respondents. "Ice," nearly 100 percent pure methamphetamine, is not very available in most cities, except in Honolulu, where it is widely available according to both the law enforcement and epidemiologic sources.

According to most law enforcement, epidemiologic, and ethnographic sources (in Billings, Columbia [SC], Denver, El Paso, Memphis, Portland [ME], St. Louis, and Sioux Falls) most available methamphetamine is produced in "box labs," small, mobile, clandestine labs often located in rural areas. Additionally, methamphetamine labs run by large operations in Mexico and California produce some of the methamphetamine available in Denver, Detroit, Los Angeles, Philadelphia, Seattle, and Washington, DC.

Exhibit 2. How has methamphetamine availability changed (fall 2000 vs spring 2001)?*

A graphic with arrows showing how methamphetamine availability has changed (fall 2000 vs spring 2001) by respondent type (L= Law Enforcement Respondent and E= Epidemiological Respondent ).* Methamphetamine availability is up in Billings (L), Birmingham (L), Chicago (L), Columbia (L), Denver (L), Detroit (E), Honolulu (L), Memphis (L), Portland (L), Seattle (L and E), Sioux Falls (L), and Washington, DC (L and E). Methamphetamine availability is stable in Baltimore (L), Billings (E), Birmingham (E), Boston (L), Chicago (E), Denver (E), Detroit (L), El Paso (L), Honolulu (E), Los Angeles (L and E), Miami (L and E), New Orleans (L), New York (L and E), Philadelphia (E), Sioux Falls (E), and St. Louis (L and E). Methamphetamine availability is down in Philadelphia (L) and Boston (E).

The manufacturing processes used to produce methamphetamine differ by region. In the Midwest, the "Nazi method" (involving ephedrine or pseudoephedrine, lithium, and anhydrous ammonia) is most often used. In the South and West, both the "coldcooking method" (involving ephedrine, red phosphorus, and iodine crystals) and the Nazi method are used. In Philadelphia, the "P2P (phenyl-2-propanone) method" (producing a lower purity methamphetamine) is most often used. According to the law enforcement source in Seattle, locally produced methamphetamine is purer than methamphetamine produced in Mexico.

Since the last reporting period, methamphetamine labs have increased in several Pulse Check cities, including Detroit, Memphis, Portland (ME), St. Louis, and Sioux Falls. Local box labs or local clandestine labs have increased in Denver, Los Angeles, Memphis, Portland (ME), Sioux Falls, and Seattle. The Portland law enforcement source states that an increasing number of people, typically from the Southwest, are beginning to create methamphetamine labs in that city. The Denver law enforcement source reports that methamphetamine produced by the Nazi method is increasing. The Seattle law enforcement source states that although the number of local box labs has increased, law enforcement officials focus their efforts on the large labs. The Memphis law enforcement source states that more amphetamine is being produced than methamphetamine, and the Denver epidemiologist reports that dietary supplements are often used in the methamphetamine production process.

What are methamphetamine prices and purity levels across the country? (Exhibit 3) Reported gram prices (the most common unit of methamphetamine sold) vary widely: $100 in the Northeast (Boston and Philadelphia reporting), $80–$175 in the South, $330 in Chicago, and $20–$300 in the West.

Between fall 2000 and spring 2001, prices remained relatively stable, except in Memphis, where prices declined slightly according to the law enforcement source, and in Chicago, where prices increased according to the law enforcement source.

Methamphetamine purity levels, reported by only seven sources, vary widely, ranging from 15–35 percent in Los Angeles to 90–95 percent in Memphis. Since the last reporting period, purity levels changed in several cities: according to the law enforcement source in Denver and Los Angeles, purity increased, possibly because high-purity methamphetamine produced in local labs by the Nazi method has replaced lower purity methamphetamine produced in Mexico. Similarly, the law enforcement source in Seattle states that the purity of methamphetamine produced in Mexico decreased because it has been diluted with methylsulfonyl methane (MSM) and that locally produced methamphetamine is often of higher purity.

How is methamphetamine referred to across the country? (Exhibit 4) Across the country, methamphetamine is often referred to as "meth," "speed," "crank," and "crystal." Other slang terms vary by region and tend to be based on the color or consistency of the available methamphetamine, such as "clear," "glass," "yellow girl," and "cinnamon." Often terms are based on production methods: "bathtub meth" refers to methamphetamine manufactured in bathtubs, and "Christmas tree meth" refers to green methamphetamine produced using Dranoฎ crystals.

Exhibit 4. How is methamphetamine referred to in different regions of the country?

Exhibit 4. Map of the US showing how is methamphetamine referred to in different regions of the country. In the West methamphetamine is referred to as glass, baggies, window, and yellow girl. In Honolulu methamphetamine is referred to as clear, cloud, ice, batu, and shabu. In the Midwest methamphetamine is referred to as ice, peanut butter, glass, anhydrous, soap, fire, nazimeth, bathtub meth, CR, chemical, california, spackle, getgo, white crosses, speckled birds, yellow jackets, christmas trees, black beauty, poppers, and pink hearts (also known by the color of the substance: red, black, brown, white, white rock, pink). In the Northeast methamphetamine is referred to as hydro, dro, 8 ball, OZs, elbows, and half elbows. In the South methamphetamine is referred to as ice, blade, snow, christmas tree meth, holiday meth, cinnamon (pink), X's and O's, hugs and kisses, sugar, good glass, hydro, and rice krispy.

How is methamphetamine packaged? According to law enforcement, epidemiologic, and ethnographic respondents, methamphetamine is most commonly packaged in plastic sandwich or zipper bags, as reported in the last Pulse Check. Additional types of packaging vary widely: it is packaged in folded paper in Detroit, El Paso, Los Angeles, and Memphis; small coin zipper bags in El Paso, Honolulu, and Washington, DC; tied-off corners of plastic bags in St. Louis and Sioux Falls; cellophane or plastic wrap with duct tape in Denver and Los Angeles; vials in Miami and Seattle; and balloons in Denver. It is sold loose in rock form, like crack, in Birmingham, St. Louis, and Seattle. Few sources in the Northeast responded to this question, in keeping with the lower availability in that region; the widest variety of packaging was reported in the West, corresponding to the wider availability in that region.

METHAMPHETAMINE: THE SELLERS

How are street-level methamphetamine sellers organized? According to law enforcement, epidemiologic, and ethnographic respondents, methamphetamine sellers are predominantly independent in the Midwest, mostly independent in the Northeast (except in Philadelphia, where biker and organized crime groups are the predominant sellers), and both independent and organized in the South and West. According to the epidemiologist in St. Louis, the affiliation of methamphetamine distributors depends on the source: independent sellers distribute locally produced methamphetamine, and organized sellers distribute Mexican methamphetamine. In Honolulu, sellers are fairly independent with two to three "runners," and some are affiliated with Mexican nationals.

How is street-level methamphetamine sold? According to law enforcement, epidemiologic, and ethnographic respondents, methamphetamine is sold using a variety of methods. The most common are hand-to-hand sales through acquaintance networks. Many sales also involve beeper or cell phone technology (as reported in 12 cities), and in 7 cities (Billings, Birmingham, Denver, Honolulu, Memphis, Philadelphia, and St. Louis), delivery type services are used.

How old are street-level methamphetamine sellers? Law enforcement, epidemiologic, and ethnographic respondents across the Nation report methamphetamine sellers as predominantly young adults (18–30 years), with a few exceptions: according to four sources (the law enforcement sources in Los Angeles, Memphis, and Sioux Falls, and the epidemiologic source in St. Louis), sellers are evenly split between young adults and adults (>30 years), and according six sources (the law enforcement sources in Baltimore, Columbia [SC], Philadelphia, Portland [ME], and St. Louis, and the Billings epidemiologic source), they are mostly adults.

What other drugs do street-level methamphetamine sellers sell? Similar to reports in the last Pulse Check, most (13 of 22) law enforcement, epidemiologic, and ethnographic respondents agree that methamphetamine sellers do not typically sell other drugs, but all respondents in the West (5 of 5) report that methamphetamine sellers do sell other drugs, namely heroin, crack and powder cocaine, and marijuana. Additionally, methamphetamine sellers often sell cocaine or ecstasy in Memphis, ecstasy in Miami, and powder cocaine and club drugs (including ecstasy, GHB, and ketamine) in Washington, DC.

Do street-level methamphetamine sellers use their own drug? Most law enforcement, epidemiologic, and ethnographic respondents (15 of 23) report that street-level methamphetamine sellers are very likely to use the drug, as reported in the last Pulse Check. Reported levels of likeliness to use the drug are highest among western sources. According to the St. Louis epidemiologist, independent sellers are very likely to use the drug, but organized sellers are not very likely to use the drug.

Are street-level methamphetamine sellers involved in other crimes? (Exhibit 5) According to most law enforcement, epidemiologic, and ethnographic respondents, methamphetamine sellers continue to be somewhat involved or very likely to be involved in other crimes, most commonly domestic violence, nonviolent crimes, and other violent crimes. Furthermore, methamphetamine sellers who are organized are reported as more likely to be involved in other crimes than those who are independent. Methamphetamine sellers seem particularly involved in domestic violence: according to 34 law enforcement and epidemiologic respondents, methamphetamine sellers account for 44 percent of the domestic violence among drug sellers, compared with only 24 percent for crack cocaine sellers, 20 percent for powder cocaine sellers, and 9 percent for heroin sellers.

Exhibit 5. In what other crimes are illicit drug sellers involved, by different drugs, across Pulse Check sites?

Exhibit 5. Five pie charts showing what other crimes illicit drug sellers are involved, by different drugs (methamphetamine, heroin, crack, powder cocaine, and marijuana) and crime type (domestic violence, gang-related crimes, violent crimes, nonviolent crimes, and prostitution) across Pulse Check sites. The pie charts illustrate that according to most law enforcement, Epidemiologic, and ethnographic respondents, methamphetamine sellers continue to be somewhat involved or very likely to be involved in other crimes, most commonly domestic violence, nonviolent crimes, and other violent crimes. According to respondents methamphetamine sellers account for 44% of domestic violence among drug sellers, compared to 24% of crack sellers, 20% of powder cocaine sellers, and 9% of heroin sellers.

Sources: Law enforcement, epidemiologic, and ethnographic respondents

Where is methamphetamine sold? (Exhibit 6) The geographic location of methamphetamine sales varies widely by region. In the West, except for Honolulu (where sales occur in the central city), respondents agree that sales occur in all areas of the city: suburban, rural, and central. In the Midwest, respondents cite mostly rural areas for methamphetamine sales, except in Chicago, where suburbs are mentioned. In the Northeast, rural areas are mentioned by the law enforcement sources in Boston and Portland (ME), and all areas are mentioned in Philadelphia. Epidemiologists in the Northeast did not respond to this question. In the South, sales settings vary: all areas are mentioned in Birmingham; suburbs are mentioned in Columbia (SC) and El Paso; the central city is mentioned in Memphis and Washington, DC; and suburbs and the Miami Beach area are mentioned in Miami.

All law enforcement, epidemiologic, and ethnographic respondents in the West report that outdoor and indoor sales are equally common. In the other three regions, indoors sales are generally more common than outdoors sales, but several respondents (in Birmingham, Memphis, Philadelphia, Sioux Falls, and Washington, DC) report that outdoor and indoor sales are equally common. The most frequently mentioned specific sales settings, according to law enforcement, epidemiologic, and ethnographic respondents, continue to be private residences, followed by nightclubs and bars, private parties, and inside cars.

For users settings, epidemiologic and ethnographic sources responded, except for the sources in Baltimore, Birmingham, Columbia (SC), New Orleans, New York, and Portland (ME).

METHAMPHETAMINE: THE USERS

How have novice methamphetamine treatment clients changed between fall 2000 and spring 2001? Most (9 of 15) nonmethadone treatment respondents report that the number of novice methamphetamine users in treatment (defined as any drug treatment client who has recently begun using methamphetamine) is stable, with a few exceptions: novice users increased in Billings, Denver, El Paso, and Sioux Falls; they declined in Portland (ME) and among adolescents in Honolulu. Methadone treatment sources did not provide information on methamphetamine users or methamphetamine treatment clients.

How old are methamphetamine users? (Exhibit 7) As reported in the last Pulse Check, the predominant age of methamphetamine users varies by city, according to 15 epidemiologic and ethnographic sources, with most (8) reporting young adults (18–30 years) as the predominant users (in Chicago, El Paso, Los Angeles, Memphis, Miami, St. Louis, Sioux Falls, and Seattle). Additionally, four respondents (in Billings, Denver, Philadelphia, and Washington, DC) cite adults (>30 years) as the predominant methamphetamine users, two (in Birmingham and Detroit) cite both young adults and adults, and the Honolulu source cites adolescents and young adults. Based on regions, no patterns in the age of methamphetamine users emerged. Most (8 of 12) non-methadone treatment providers concur that methamphetamine users are predominantly young adults.

Then and Now:

How have methamphetamine user characteristics changed (fall 2000 vs spring 2001)?

According to epidemiologic and ethnographic sources, methamphetamine user characteristics have changed in several areas:

  • Billings, Detroit, and Washington, DC: Although adults (>30 years) are the predominant users, young adults (18–30 years) are cited as emerging user groups.

  • Sioux Falls: Pre-adolescents (<13 years) are cited as an emerging user group.

  • Detroit and Honolulu: Most methamphetamine users are male, but female methamphetamine users have increased.

  • Los Angeles: Hispanics and Asian/Pacific Islanders are increasingly using methamphetamine.

  • Washington, DC: Hispanics are cited as an emerging methamphetamine user group.

  • Los Angeles and Honolulu: Methamphetamine users who reside in suburban areas have increased.

  • St. Louis: Methamphetamine users who reside in central city and suburban areas are emerging groups.

  • Honolulu, El Paso, and St. Louis: Injecting as a route of methamphetamine administration is increasing.

Are there any gender differences in who uses methamphetamine? According to most (11 of 15) epidemiologic and ethnographic respondents, methamphetamine users are predominantly male, as reported in the last Pulse Check. Only three sources (in Billings, Los Angeles, and Sioux Falls) report methamphetamine users as split evenly between genders, and only in El Paso are methamphetamine users primarily females. By contrast, most (8 of 12) non-methadone treatment respondents report that males and females are equally likely to use methamphetamine; the remaining sources report that users tend to be males.

*Notes: Epidemiologic sources did not respond in Baltimore, Columbia (SC), New Orleans, and Portland (ME); non-methadone treatment sources did not respond in Baltimore, Boston, Chicago, Detroit, Honolulu, Memphis, Miami, New Orleans, New York, Seattle, and Washington, DC. If respondents cited methamphetamine users as evenly split between two age groups, that respondent is listed under both age groups. Two non-methadone treatment sources from Sioux Falls responded.

Is any racial/ethnic or socioeconomic group more likely to use methamphetamine? As reported in the last Pulse Check, methamphetamine users tend to be Whites and overrepresented compared with the general population, according to nearly all (17 of 19) epidemiologic and ethnographic sources. In Billings, they are split evenly between Whites and Native Americans, and in Honolulu, they are be split evenly between Whites and Asian/Pacific Islanders. Most non-methadone treatment respondents agree with their epidemiologic and ethnographic counterparts.

Methamphetamine users continue to be of low or middle SES, with 7 of 16 epidemiologic and ethnographic sources reporting them as having low SES backgrounds and 9 reporting them as being middle SES. All (12) non-methadone treatment respondents concur with epidemiologic sources that users tend to be of low or middle SES.

Where do methamphetamine users tend to reside? Depending on the region, the residences of methamphetamine users vary widely. According to epidemiologic and ethnographic sources, most methamphetamine users reside in suburban and rural areas in the Midwest; in central city areas in the Northeast; and in rural areas, suburbs, and central city areas in the South and West. Most non-methadone treatment respondents agree with their epidemiologic counterparts.

How do methamphetamine users wind up in treatment?

Courts and the criminal justice system are the most common referral sources for clients entering treatment for methamphetamine addiction, according to non-methadone treatment respondents. Individual referrals follow closely as the second most common referral source.

How do most methamphetamine users take the drug? Route of administration for methamphetamine varies widely, according to epidemiologic and ethnographic sources. Most (3 of 4) responding sources in the West (in Denver, Los Angeles, and Honolulu) report smoking as the predominant route of administration, but the Seattle epidemiologic source reports oral ingestion as the predominant route. Snorting predominates in three non-western areas (Chicago, Memphis, and Washington, DC), oral ingestion predominates in Miami, and smoking is most common in Sioux Falls and New York. In Philadelphia and Birmingham, snorting and injection are mentioned, in El Paso injection and oral ingestion are mentioned, and in Detroit, snorting and oral ingestion are mentioned. According to the Los Angeles and St. Louis epidemiologic sources, methamphetamine users often switch routes of administration. Most nonmethadone treatment respondents agree with their epidemiologic counterparts about predominant route of administration.

What other drugs do methamphetamine users take? Methamphetamine users take a variety of other drugs, according to epidemiologic and ethnographic respondents, and as reported in the last Pulse Check. The most common drugs used in combination with methamphetamine are marijuana (in Birmingham, Detroit, Los Angeles, Memphis, Philadelphia, and St. Louis) and ecstasy (in Miami and Washington, DC). Non-methadone treatment sources agree that marijuana is often used in combination with methamphetamine, as reported in Billings, Denver, Los Angeles, Philadelphia, St. Louis, and Sioux Falls.

Where and with whom do methamphetamine users take the drug? (Exhibit 6) According to nearly all (17 of 27) epidemiologic, ethnographic, and non-methadone treatment respondents, methamphetamine is generally used indoors and in private. Methamphetamine use is most often a group activity, according to the vast majority (21 of 27) of those respondents. Additionally, the Detroit and Seattle epidemiologic sources and the Philadelphia and Honolulu non-methadone treatment sources report that most methamphetamine users take the drug both alone and in groups; the Miami and Los Angeles epidemiologic sources report that most use the drug alone.

The most frequently mentioned user settings, according to epidemiologic and ethnographic respondents are private residences, followed by private parties and nightclubs. Other common use settings include inside cars and raves and concerts, similar to those reported as sales settings. Moreover, respondents in the South and West report more user settings than those in other regions. Nonmethadone treatment respondents also report private residences as the most common setting for methamphetamine use, followed by private parties, inside cars, and parks and playgrounds.
