Smoking pot by means of a bong would not defend the nonsmokers within the room from the hazards of secondhand smoke, a brand new examine warns.
Bongs have been touted as a protected strategy to defend nonsmokers from secondhand marijuana smoke. However it might expose them to extraordinarily excessive concentrations of nice particulate matter — 5 to 10 occasions larger than ranges from wildfires within the San Francisco Bay Space in September 2020, in keeping with senior researcher Katharine Hammond. She is a professor of environmental well being sciences on the College of California, Berkeley.
“Hashish bong smoking within the house generated a number of occasions larger particulate matter than tobacco cigarettes and hookah,” Hammond mentioned.
Even 12 hours after pot smoking stopped, concentrations of nice particulate matter remained excessive and unhealthy for delicate individuals, the examine discovered. “Secondhand hashish smoke significantly exceeds air air pollution requirements,” Hammond warned.
A bong is a water pipe that filters and cools pot smoke to offer a smoother, extra intoxicating impact.
“There isn’t a risk-free degree of publicity to secondhand tobacco smoke, and secondhand hashish smoke incorporates related toxins and is presumably not protected,” Hammond mentioned.
Secondhand marijuana smoke has the potential to trigger vital illness, and smoking pot ought to be included with tobacco cigarettes in clear indoor air insurance policies, she steered.
“The antagonistic well being results of nice particulate matter are properly established,” Hammond mentioned, including that publicity has been proven to trigger early dying, decreased lung operate, and elevated danger of dying from lung most cancers and coronary heart illness.
Matthew Springer, a professor of drugs within the division of cardiology on the College of California, San Francisco, mentioned it is clear that secondhand smoke from each tobacco and hashish can attain unhealthy ranges for bystanders. And, he added, utilizing a bong generates a number of smoke.
“The smoke that passes by means of the water continues to be smoke that will get inhaled after which exhaled, and any smoke generated by the fabric itself because it’s smoldering goes so as to add to the general secondhand smoke within the room,” Springer mentioned. “That would appear to go with out saying, however as with every gadget perceived by the general public as safer, it is helpful to see actual numbers indicating that, certainly, use of bongs doesn’t stop bystanders from being uncovered to vital quantities of secondhand smoke.”
Whether or not or not bigger particles within the water are eliminated, it is the nice particles that make it far into the lungs and harm them, in addition to the guts and blood vessels, Springer famous.
“Whether or not or not bong use ends in extra secondhand smoke than different merchandise, clearly it might nonetheless end in excessive ranges, and it was notable that the stuff persevered within the room for hours,” he added.
For the examine, Hammond and her UC Berkeley colleague Patton Khuu Nguyen measured ranges of nice particulate matter — referred to as PM2.5 — earlier than, throughout and after eight pot smoking periods in a single front room. An aerosol monitor measured PM2.5 concentrations the place a nonsmoker may sit.
Throughout six periods, bong smoking elevated PM2.5 ranges between 100-fold and 1000-fold. They rose greater than 20-fold in two different periods, the investigators discovered.
The examine authors additionally discovered that hashish bong smoking generated PM2.5 ranges 4 occasions greater than that produced by cigarettes or smoking tobacco in a waterpipe.
As such, Hammond mentioned efforts to cut back publicity to secondhand marijuana smoke are wanted. Such measures might embody having marijuana smoke-free environments like these for tobacco and never smoking indoors.
“Bong smoking results in extraordinarily excessive and really unhealthy secondhand smoke particle concentrations above [U.S. Environmental Protection Agency] requirements that persist even hours after smoking ceases,” she mentioned. “Our report and former research ought to information efforts to coach the general public on the potential antagonistic well being results of secondhand hashish smoke on nonsmokers.”
Cynthia Hallett, president and CEO of Individuals for Nonsmokers’ Rights, reviewed the examine findings.
“There are a number of similarities between secondhand tobacco smoke and secondhand hashish smoke,” she mentioned. “Each have carcinogens and toxins and have the potential to trigger respiratory issues, whether or not that is bronchial asthma or lung most cancers.”
Hallett is not towards legalization of marijuana or smoking it, however she thinks that bystanders ought to be shielded from its secondhand smoke. She sees a parallel between the best way tobacco firms fought smoke-free legal guidelines and the way hashish is being commercialized utilizing most of the identical ways to thwart indoor smoking restrictions.
“The problem is that we’re getting pushback from marijuana proponents and hashish business proponents in attempting to advocate for indoor smoking areas,” Hallett mentioned.
Having no-pot-smoking legal guidelines, like no-tobacco-smoking legal guidelines, is crucial to guard individuals from the harms of secondhand marijuana smoke, she mentioned.
“We need to ensure that nonsmokers are usually not unfairly uncovered to dangerous merchandise,” Hallett mentioned. “We additionally do not need to construct one other technology hooked on tobacco or hashish merchandise.”
The examine was revealed on-line March 30 in JAMA Community Open.
