Note(s):
  • For the combined analysis, the original sampling weights of respondents were adjusted by a factor of two (because there are two quarters).
  • The estimates in the "beliefs about when it is safe to drive after using cannabis" section reflect the percentage of respondents within each belief category who reported driving within two hours of consuming cannabis. The "other" category includes: weight, quantity and method of consumption.
