Eric, good job!!

Could not understand the figure. What does the "not use" means for each of the categories?

Hi Melecio,

Thank you for your question regarding the figure labels.

The "Did not use in 9th grade" label and each corresponding green bar in the figure represents the percentage of respondents who later smoked marijuana in 11th grade and did not use each tobacco product in 9th grade. For example, if a respondent did not use e-cigarettes in 9th grade but later smoked marijuana in 11th grade, they would be part of the 7.3% of people in the "E-cigarettes" row of the figure.
