According to the 2005 National Survey on Drug Use and Health (NSDUH), an approximated 10.4 million Americans aged 12 or older used methamphetamine at least once in their life for recreational use, representing 4.3% of the U.S. population in that age group. The amount of past year methamphetamine users in 2005 was approximately 1.3 million (0.5% of the population aged 12 or older) and the amount of past month methamphetamine users was 512,000 (0.2%).
Among 12-17 year olds surveyed as part of the 2005 NSDUH, 0.3% admitted past month methamphetamine use. Additional NSDUH results demonstrate that 0.6% of 18-25 year olds and 0.1% of those aged 26 or older reported meth use in the last 30 days.
The 2005 NSDUH results also show that there were 192,000 individuals aged 12 or older who had used methamphetamine for the first time within the last year. This is a statistically important reduction from 2004 when there were 318,000 past year methamphetamine initiates.
Results of the 2006 Monitoring the Future survey demonstrate that 2.7% of eighth graders, 3.2% of tenth graders, and 4.4% of twelfth graders reported lifetime use of meth. During 2the year 2005, these percentages were 3.1%, 4.1%, and 4.5%, respectively.
The Youth Risk Behavior Surveillance (YRBS) study by the Centers for Disease Control and Prevention (CDC) surveys high school students on numerous risk factors such as drug and alcohol use. Results of the 2005 survey show that 6.2% of high school students admitted using methamphetamine at some point in their lives. This is a decrease from 7.6% in 2003 and 9.8% in 2001.
Long-term methamphetamine abuse can lead to addiction, anxiety, insomnia, mood swings, and violent behavior. In addition, psychotic symptoms like paranoia, hallucinations, and delusions (such as the sensation of bugs crawling under the user’s skin) can occur. The psychotic symptoms of meth use can last for months or years after methamphetamine use has stopped.
Of an approximated 108 million emergency department (ED) admissions in the U.S. during 2005, the Drug Abuse Warning Network (DAWN) estimates that 1,449,154 ED visits were related with drug misuse or abuse. DAWN data demonstrate that methamphetamine was involved in 108,905 of the drug-related ED admissions.
From the year 1995 to the year 2005, the number of admissions to treatment in which methamphetamine was the principal drug of abuse increased from 47,695 in 1995 to 152,368 in 2005. The methamphetamine admissions represented 2.8% of the total drug/alcohol admissions to treatment in the year 1995 and 8.2% of the treatment admissions in the year 2005. The average age of the individuals admitted to treatment for methamphetamine/amphetamine addiction in 2005 was 31 years.
