Note: To get the percent of occurrence of any variable, divide by the enter sample. For example, there are 2728 participants in the total sample, 343 of which identified as current marijuana users. To get the percent of current marijuana users in the sample, divide 343 by 2728 and move the decimal two places to the right - which is 12.6%
