To the Editor The debate on effects of state medical and recreational marijuana laws (MMLs/RMLs) is at the forefront of drug policy. Assessing associations of MMLs/RMLs with youth marijuana use is critical given marijuana’s potential for long-term negative effects on brain development and function.1,2 Anderson et al,3 using Youth Risk Behavior Survey (YRBS) data, report MMLs are not associated with youth marijuana use and RMLs are associated with reduced use. However, their analyses include substantial methodologic flaws that may undermine these findings.
