Smoking marijuana indoors can produce extremely high indoor particulate matter of fine inhalable particles with emission rates greater than tobacco cigarettes.
The marijuana joint’s emission rate was 3.5 times that of the tobacco cigarette. The bong, glass pipe, and vaping pen had higher rates than the others, with the vaping pen being the highest. Stanford University, American Nonsmokers’ Rights Foundation (ANRF), California Every Brain Matters
Exposure to fine particulate matter can exacerbate health problems, especially for people with respiratory conditions such as asthma, bronchitis, or COPD.
Some of the known carcinogens or toxins in marijuana smoke include: Acetaldehyde, ammonia arsenic, benzene, cadmium, chromium, formaldehyde, hydrogen cyanide, isoprene, lead, mercury, nickel, and quinoline.
Marijuana also can be contaminated with mold, insecticides, or other chemicals that may be released in secondhand smoke. ANRF
If someone inhales secondhand marijuana smoke for 60 seconds, for the next 90 minutes, their blood vessels will be affected. Cannabis smoke increases the chances of developing hardened or clogged arteries, which can cause a heart attack or stroke. It’s a 90-minute impairment from which our systems never fully recover. American Addiction Centers
Secondhand exposure to marijuana smoke can lead to cannabinoid metabolites in body fluids sufficient for positive results on testing of oral fluids, blood, and urine. It can also lead to psychoactive effects.
Secondhand smoke can cause serious health problems, especially in infants and children or anyone with a chronic lung condition. Cannabinoids, the chemicals that cause the high (a contact high), get into the bodies of people nearby, including children. Harvard Medical School Harvard Health Publishing
As a fitness professional and a professional dancer, I almost lost my business after Oregon legalized recreational cannabis, due to the effects of secondhand and third-hand cannabis/hemp smoke, terpene extraction, and other processing chemical practices. I experienced cannabis exposure in my condominium unit from neighboring residents, users in public spaces including restaurants, parks, grocery stores,…
“I couldn’t breathe. I’m prone to asthma attacks, and every time my next door neighbors smoked marijuana in their apartment and on their patio, it irritated my lungs. I would cough so much. I’d throw up and couldn’t breathe.” Marijuana use. I almost died from it, and I wasn’t even the one using! I was…
