Table 2.

Fixed effects model for use of inhaled, dried Cannabis flower on reported symptom intensity level by reported symptom

(1) (2) (3) (4)
All Agitation/irritability Anxiety Stress
Post-cannabis use − 3.824*** (0.110) − 4.332*** (0.198) − 3.474*** (0.125) − 3.977*** (0.122)
Constant 5.452*** (0.055) 5.754*** (0.099) 5.246*** (0.062) 5.540*** (0.061)
Observations 4612 844 1996 1772
R-squared 0.644 0.707 0.635 0.686
Number of users 670 206 441 360

Each column represents a separate regression. The outcome is the reported symptom level. The explanatory variable is a dummy variable that equals to one if symptom level is reported after cannabis use and equals zero if reported before cannabis use. Models are estimated using an individual fixed effects model. Standard errors, clustered at the individual user level, are shown in parentheses
