Although there’s nothing quite like the stale smell that remains after smoking tobacco, weed smoke also deposits compounds on surfaces that new research suggests can be reduced by ozone, which is found in both indoor and outdoor air. Plenty is known about second- and third-hand smoke (THS) — which are reactive chemicals that remain in the air or are deposited on surfaces like walls, windows, clothing and upholstery, respectively — from tobacco. The same cannot be said for cannabis smoke, which is less studied and chemically distinct from tobacco smoke. Researchers say 400-year-old cave art tied to hallucinogenic flower Using alcohol and bud simultaneously not associated with engaging in certain risky activities: study Study: Cannabis could be 25 per cent stronger today than it was 50 years ago To explore how ozone, a component found in both indoor and outdoor air, can react with the psychoactive cannabis compound tetrahydrocannabinol (THC), researchers coated glass and cotton cloth with a THC solution. They then exposed the surfaces to concentrations of ozone that could exist in indoor air. Appearing in the American Chemical Society’s (ACS) publication, Environmental Science & Technology , the reaction between weed smoke and ozone produced “new compounds, which they characterized for the first time,” researchers report. “Over time, the amount of THC on glass and cotton decreased, while the quantities of three THC oxidation products (identified in the study abstract as epoxide, dicarbonyl and secondary ozonide THC reaction products) increased,” according to the ACS . That is important since third-hand smoke “lingers long after a person stops smoking.” The team also used a smoking machine to deposit cannabis smoke on cotton. When that was exposed to ozone, “the same three compounds formed at roughly the same rate as observed for the THC-coated cloth,” the ACS reports. “Nicotine is semi-volatile…
