THC (tetrahydrocannabinol), the psychoactive compound in cannabis, can remain in the air for a short period after smoking or vaping, typically around 30 minutes to a couple of hours, depending on ventilation and air circulation. However, its odor can linger longer in enclosed spaces. Factors such as temperature, humidity, and the presence of other substances can also influence how long THC and its scent persist in the air.
