Note. Numbers in each cell of the table are percentages and counts in parentheses. Due to survey weighting, the percentages and counts do not exactly line up (e.g., 41 of 46 is 89%, not 69%). Chi-square tests compared self-reported use that night between those with and without a plan to use that night. “—” indicates that P could not be computed due to too few cases in at least one cell. LSD = lysergic acid diethylamide; MDA = 3,4-methylenedioxyamphetamine; PMA = paramethoxyamphetamine
