Second-Hand Marijuana Smoke May Damage Blood Vessels as Much as Tobacco Smoke

[WHO IS SERAFIN]

And let the excuses begin on why another study of thousands is wrong. Is this what happened when studies began on how bad smoking was for your health? And start..........

A new study conducted by researchers from the University of California, San Francisco suggests that exposure to second-hand marijuana smoke may be just as damaging to blood vessel function as exposure to second-hand cigarette smoke.



As part of the study, researchers exposed laboratory rats to second-hand marijuana smoke using a modified cigarette smoking machine. The researchers utilised a high-resolution ultrasound machine to analyze the rats' blood vessel function 10 minutes before exposure and 40 minutes after exposure. The blood vessel function of the rats exposed to second-hand marijuana smoke for 30 minutes reduced by 70%.



"Most people know second-hand cigarette smoke is bad for you, but many don't realise that second-hand marijuana smoke may also be harmful," said Dr. Matthew Springer, senior author of the study and associate professor of medicine at the University of California, San Francisco's cardiology division. "If you're hanging out in a room where people are smoking a lot of marijuana, you may be harming your blood vessels," he said. "There's no reason to think marijuana smoke is better than tobacco smoke. Avoid them both."



Poor blood vessel function may raise the risk of developing atherosclerosis and could result in a heart attack. Atherosclerosis is the health condition that causes a build-up of plaque in the arteries, which narrows them and restricts blood flow.



After the initial experiment, the researchers then exposed the rats to second-hand smoke from marijuana that did not contain tetrahydrocannabinol (THC) - marijuana's active compound.
