Psychiatric implications of adolescent methamphetamine exposures

Area of Science:

• Toxicology
• Adolescent Health
• Public Health

Background:

• Methamphetamine abuse is a growing public health concern, particularly among adolescents.
• Adolescent methamphetamine abuse is associated with increased risks of depression and suicidal ideation.
• Previous data suggest a rise in suicide attempts within this demographic.

Purpose of the Study:

• To investigate adolescent methamphetamine exposures reported to the California Poison Control System (CPCS) between 2000 and 2009.
• To compare rates of suicidal ideation and suicide attempts in adolescent methamphetamine exposures with population-based survey data.
• To analyze the severity and characteristics of methamphetamine exposures in adolescents.

Main Methods:

• A retrospective review of CPCS records for methamphetamine exposures in individuals aged 11–18 years from 2000–2009.
• Abstraction of patient charts to categorize severity using National Poison Data System Medical Outcome Criteria.
• Analysis of demographic data, presenting symptoms, and reported events, including suicidal ideation and attempts.

Main Results:

• 293 adolescent methamphetamine exposures were identified and categorized by severity (major, moderate, minor).
• Females (57%) were more frequently reported than males.
• Agitation was the most common symptom (39%), with suicidal ideation (31%) and suicide attempts (21%) being the most frequent events.

Conclusions:

• Adolescent methamphetamine exposures reported to the CPCS were associated with significantly higher rates of suicidal ideation and suicide attempts.
• These rates were disproportionately elevated compared to population-based surveys during the same decade.
• Findings highlight the critical need for targeted interventions and support for adolescents experiencing methamphetamine exposure and associated mental health crises.
