When marijuana is smoked, how does it interact with the surrounding air? (i.e. does it dissipate? How does the smoke travel, move and thin out over time?) What are the processes involved when the smoke grows in size and thins out as it expands?
I’m trying to figure out how marijuana smoke interacts with surrounding air after it is smoked. So, after someone blows out the smoke, how long does it take to dissipate into the air? I’m trying to get as technical of an answer as possible but still be easily understandable. Reason I ask is because a friend who lives in a dorm room (who DOES NOT smoke marijuana) is being accused of smoking marijuana in his room and I’m trying to help provide him a defense.
