Smoking cannabis exposes the body to a few of the same hazardous chemicals launched from tobacco, but at lower levels, according to a brand-new study.
Scientists at Dana-Farber Cancer Institute and the Centers for Disease Control and Prevention took a look at the levels of several unsafe chemicals in the blood and urine of 245 volunteers.
Some of the volunteers didn’t smoke, some smoked either weed or tobacco and dome smoked a combination of both.
They discovered that those who just smoked cannabis still had several smoke-related harmful chemicals in their system – but at lower levels than those who also or only smoked tobacco
These included napthalene, acrylonitrile and acrylamide – toxic chemicals that can trigger liver damage, are connected to cancer and a variety of other health concerns, scientists declare.
However, another chemical, acrolein, which is understood to add to cardiovascular disease in tobacco cigarette smokers – only increased with tobacco smoking not marijuana.
The team state minimizing acrolein direct exposure from tobacco cigarette smoking and other sources might be a strategy for lowering the threat of establishing heart disease.
Those who just smoke marijuana still had several smoke-related hazardous chemicals in their system – but at lower levels than those who likewise or just smoke tobacco.
Marijuana use is on the rise in the US with a growing variety of states legalising it for medical and nonmedical purposes – consisting of five more states in the 2020 election.
‘ The increase has restored issues about the potential health results of marijuana smoke, which is understood to contain a few of the very same toxic combustion products discovered in tobacco smoke,’ stated the senior author, Dana Gabuzda, MD, of Dana-Farber.
‘ This is the very first research study to compare direct exposure to acrolein and other hazardous smoke-related chemicals in time in special marijuana cigarette smokers and tobacco smokers, and to see if those direct exposures are related to heart disease.’
The research study involved 245 HIV-positive and HIV-negative individuals in three research studies of HIV infection in the United States – HIV contaminated people were utilized due to the fact that of high tobacco and cannabis smoking cigarettes rates in this group.
The scientists gathered data from participants’ medical records and survey results and analysed their blood and urine samples for substances produced by the breakdown of nicotine or the combustion of tobacco or marijuana.
Combining these datasets allowed them to trace the presence of particular toxic chemicals to tobacco or marijuana cigarette smoking.
They could also see if any were connected with an increased risk of cardiovascular disease.
The private investigators discovered that individuals who exclusively smoked marijuana had greater blood and urine levels of numerous smoke-related toxic chemicals such as naphthalene, acrylamide, and acrylonitrile metabolites than non-smokers did.
Nevertheless, the concentrations of these compounds were lower in marijuana-only cigarette smokers than in tobacco cigarette smokers.
Acrylamide is used to make paper, plastics and dyes and produced when vegetables are heated up to a high temperature – it’s also an element of tobacco smoke.
The chemical is considered a ‘probably human carcinogen’ by the US National Toxicology Program and the American Cancer Society.

Another chemical discovered as a by-product of cigarette smoking weed and tobacco is Acrylonitrile, which is used to make plastics and fibers.
The World Health Organisation said cigarette smoke can be a significant source of acrylonitrile in indoor air pollution and is seen as a possible carcinogen.
The detectives likewise found that exposure to acrolein, a chemical produced by the combustion of a variety of materials, increases with tobacco smoking cigarettes however not cannabis smoking cigarettes and adds to cardiovascular disease in tobacco cigarette smokers.
The findings suggest that high acrolein levels may suggest increased risk of heart disease and that minimizing exposure to the chemical might reduce threat.
‘ This is necessary for individuals contaminated with HIV, the virus that triggers AIDS, given high rates of tobacco smoking cigarettes and the increased threat of heart disease in this group.’
‘ Our findings suggest that high acrolein levels may be used to identify patients with increased cardiovascular threat,’ Gabuzda stated, ‘which reducing acrolein exposure from tobacco smoking cigarettes and other sources might be a method for reducing danger.’
The findings have actually been released in the journal EClinicalMedicine.
