Degenerates in my high school back in the day did it all the time. Not everything in smoke is burnt matter. There are always particles that are liberated and dispersed by convection along with combusted materials. It's not the purest way to trip, but then again that level may suit druggies' moods from time to time, especially when mixed with their beloved pot.
Pro druggie "experts" often claim things that druggies know is bs but won't admit it's bs. Such as spurious claim that THC is completely depleted in exhalations. Potheads claim this time and time again, but their fondness for "hot boxing" and blowing the smoke into sex partners' mouths for a second hit demonstrates that potheads know it still contains plenty of THC. And they know to stay away from even secondhand smoke for a month when they need to pass a drug test.
“nonsmoking people in a confined space with people smoking high-THC marijuana reported mild subjective effects of the drug—a “contact high”—and displayed mild impairments on performance in motor tasks.” - https://www.drugabuse.gov/publications/research-reports/marijuana/what-are-effects-secondhand-exposure-to-marijuana-smoke
The idea that passing exposure to pot smoke can get one high is Reefer Madness hysteria.
