Figure 2. Impairment of FMD by pulsatile exposures (2 seconds, 1 time per minute over 5 minutes) to Volcano and Yocan (handheld) marijuana aerosol generated at different temperatures.

Lowering the device temperature to a level that did not efficiently deliver THC (see the Table) did not prevent the impairment of FMD. Each colored line represents an individual rat; black bars show group means. Post‐10=10 minutes after final exposure. P values are from paired t tests except for the air group, for which the Shapiro‐Wilk test was used due to nonnormal distribution. See Figure S1 for results broken out by sex, revealing no evidence of a sex‐specific effect. FMD indicates flow‐mediated dilation; and THC, Δ‐9‐tetrahydrocannabinol.
