The Effect of E-Cigarette Taxes on Substance Use

Area of Science:

• Public Health
• Substance Use Research
• Health Economics

Background:

• Concerns exist regarding electronic nicotine delivery systems (ENDS) acting as a gateway to marijuana and harder drug use among adolescents.
• The economic impact of ENDS taxation on adolescent substance use patterns requires thorough investigation.

Purpose of the Study:

• To investigate the impact of electronic nicotine delivery system (ENDS) taxes on adolescent and young adult substance use.
• To determine if ENDS taxes influence the use of marijuana and other illicit substances.

Main Methods:

• Utilized difference-in-differences and event-study methodologies for robust causal inference.
• Employed comprehensive survey data (Youth Risk Behavior Surveillance System, Behavioral Risk Factor Surveillance System) and administrative data (Treatment Episode Data Set).

Main Results:

• A $1 increase in ENDS taxes correlated with a 1.0–1.5 percentage point reduction in teen marijuana use.
• Evidence suggests e-cigarettes and marijuana are economic complements, with tax effects moderating over time.
• No significant impact of ENDS taxes was found on admissions for drug treatment or use of other illicit drugs like cocaine, methamphetamine, or opioids.

Conclusions:

• Electronic nicotine delivery system (ENDS) taxation can be an effective public health strategy to curb adolescent marijuana use.
• Findings support the economic complementarity of e-cigarettes and marijuana, indicating potential for broader substance use policy implications.
• Long-term youth responses to ENDS taxes warrant further study to understand evolving substance use behaviors.
