Prevalence Estimates: Adolescents • Among high school seniors surveyed in 2005, 4.5% had tried meth in their lifetime (down from 8.2% in 1999). • Lifetime use among 8th and 10th graders was 3.1% and 4.1%, respectively. • Also during 2005, 2.5% of high school seniors had used meth in the last year and 0.9% had used it in the last month. SOURCE: NIDA, Monitoring the Future Study: Overview of Key Findings, 2006.
Trends in Methamphetamine Use and Initiation • In 2004, an estimated 12 million persons (4.9 percent of persons aged 12 or older) had used methamphetamine at least once in their lifetime, 1.4 million (0.6 percent) had used it in the past year, and 600,000 (0.2 percent) had used it in the past month. • Between 2002 and 2004, the number of recent methamphetamine initiates remained level at around 300,000 per year. The average age at first use among new users was 18.9 years in 2002, 20.4 years in 2003, and 22.1 years in 2004. SOURCE: National Survey on Drug Use and Health, SAMHSA, 2005.

County-Level Rankings of Meth Lab Seizures: 1H 2005 – Top 10 SOURCE: LA CLEAR, 2005 (as of 6/23/05).
Methamphetamine: A Growing Menace in Rural America • In 1998, rural areas nationwide reported 949 methamphetamine labs. • Last year, 9,385 were reported. • This year, 4,589 rural labs had been reported as of July 26. • Source: El Paso Intelligence Center (EPIC), U.S. DEA
Lab Seizure Locations • Most common meth lab facilities were single-family houses, followed by apartments, mobile homes, vehicles in traffic stops, garages, trailers, motels/hotels, businesses, desert, and storage.
Toxic Effects of Methamphetamine • Manufacturing • Abuse • Fetal exposure
Children • Children who live in and around the area of the meth lab become exposed to the drug and its toxic precursors and byproducts. • 80-90% of children found in homes where there are meth labs test positive for exposure to meth. Some are as young as 19 months old.
Children • Children can test positive for methamphetamine by: • Having inhaled fumes during the manufacturing process • Coming into direct contact with the drug • Through second-hand smoke.
Children • Hundreds of children are neglected by parents who are meth cooks. Nationally, over 20% of the seized meth labs in 2002 had children present. • In Washington State, the counties of Grays Harbor, Spokane, Thurston, and Klickitat all reported that children were found at half the labs seized in 2002. In Lewis County, children were found at 60-70 %, and in Clark-Skamania, 35%.
Children • In 2002, a total of 142 children were present at lab seizures in Riverside and San Bernardino Counties. • Most children reported as being present during a seizure were school age.
Children • Social workers now accompany law enforcement during lab seizures with children involved. • Parents are often charged with second-degree criminal mistreatment, along with manufacturing charges. • Allowing children to live in a toxic environment where additional risks of explosion and fire are high is considered to be neglect at best to child abuse.
Children are not small adults! • Different diet • Growing & developing rapidly • Higher metabolic & respiratory rate • Developing nervous system • Unusual habits (hand-to-mouth behaviors; close to floor, contact with many surfaces, at risk for all poisonings) • Biologic & developmental vulnerability
DEC RESPONSE TEAM • CORE TEAM MEMBERS: • LAW ENFORCEMENT (24/7) • CHILD PROTECTIVE SERVICES (24/7) • DISTRICT ATTORNEY’S OFFICE (24/7) • MEDICAL PERSONNEL (24/7) • “AUXILIARY” TEAM MEMBERS: • MENTAL HEALTH & THERAPEUTIC PERSONNEL FOR CHILDREN • ENVIRONMENTAL SERVICES, FIRE, & PUBLIC HEALTH • DRUG TREATMENT PROVIDERS FOR PARENTS AND FAMILY MEMBERS
