This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Area of Science:

  • Public Health
  • Epidemiology
  • Adolescent Health

Background:

  • Sexual minority youth (SMY) exhibit higher substance use rates than heterosexual peers.
  • Substance use is a significant factor in adult morbidity and mortality, linked to poorer mental health in SMY.

Purpose of the Study:

  • Document long-term trends in substance use among a large youth sample, focusing on SMY.
  • Investigate disparities in substance use behaviors between SMY and heterosexual youth.
  • Examine changes in these disparities over time for SMY.

Main Methods:

  • Analysis of 8 waves of Massachusetts Youth Risk Behavior Survey (YRBS) data (1999-2013).
  • Sample included 26,002 youth (average age 16).
  • Logistic regression models assessed trends and disparities in tobacco, alcohol, and cannabis use.

Main Results:

  • Overall youth substance use decreased between 1999 and 2013.
  • Significant disparities in substance use persisted between heterosexual youth and SMY subgroups.
  • Disparities narrowed for males but remained unchanged or worsened for females.

Conclusions:

  • Substance use trends vary across sexual minority subgroups.
  • Worsening patterns observed in female SMY highlight urgent, unmet needs.
  • Novel approaches are required to address the specific health needs of lesbian, gay, bisexual, and other sexual minority populations.
