Just as Congress is about to legalize weed for everyone,
they gotta throw this good news at us...
A new study has found that secondhand cannabis smoke from bongs
can be even more harmful than tobacco due to an increased concentration of fine particulate matter.
Researchers from the University of California, Berkeley, who published their report on the Jama Open Network this week, conducted their experiment with students from the university. They measured levels of fine particulate matter before, during and after eight cannabis social-smoking sessions in the living room of an apartment near campus.
They found that secondhand bong smoke contains fine particulate matter in much higher concentrations and is more dangerous compared with secondhand tobacco smoke.
The students, who provided their own cannabis and bongs, remained anonymous and were not observed during the two-hour smoke sessions.
“We exerted no control and gave no direction to the students on how to smoke the cannabis in the bong,” said S Katharine Hammond, a professor who oversaw the study alongside graduate student Patton Khuu Nguyen, to the San Francisco Chronicle. “They were free to smoke as much as they wanted when they started the session.”
Hammond and Nguyen used an aerosol monitor to measure the air quality before, during and after each session, which they then compared with the data collected from tobacco smokers in a hookah setting.
They found that fine particulate matter from cannabis
bong smoking was at least four times greater than
the smoke produced by tobacco.
