Notes: Standard errors, clustered at the state level, are shown in parentheses.

All models include dummy variables for gender, race, age, and grade levels. State-level covariates listed in Table 1 are included.

We define youth as current marijuana users if any days of marijuana use over the past month are reported.

The analysis sample is restricted to youth younger than 18.

E-cigarette MLSA Law is defined in the text.

One wave means one survey year.
