Secondhand Pot Smoke Just As Bad For Heart As Tobacco study, second hand smoke

The main finding was that when rats were exposed to secondhand smoke from marijuana for one minute, their arteries became less efficient at carrying enough blood for at least 90 minutes, whereas similar exposure to secondhand smoke from tobacco caused impairment that fully recovered within 30 minutes (exposure to clean air in the exposure chamber did not cause impairment). (It is important to understand that arteries of rats and humans are similar in how they respond to tobacco smoke, so the response of rat arteries to marijuana smoke is expected to be a valid indication of how human arteries respond to marijuana smoke.)

"Especially as marijuana becomes more available and acceptable, we need to learn more about how this may affect children's health and development." In the meantime, she said, "marijuana should never be smoked in the presence of children."

Smoking Marijuana and the Lungs lungs, aspergillus, second hand smoke

Since marijuana contains cancer-causing chemicals (carcinogens) similar to tobacco smoke, your risk for lung cancer may be increased if you smoke marijuana. Also, marijuana users expose their lungs to a larger amount of smoke because they tend to inhale more deeply, smoke without filters, and hold their breath when they inhale. This type of inhalation pattern exposes your lungs to more smoke than a cigarette.

 

Aspergillus can live on the marijuana plant and be inhaled in the marijuana smoke. It is not recommended that you smoke marijuana if you have cancer, are taking chemotherapy, have had a lung transplant, or have a weak immune system.

 

Second-hand smoke (inhalation of another person’s marijuana smoke) can cause serious health problems, especially in infants and children or anyone with a chronic lung condition. Second-hand marijuana smoke contains many poisons including cyanide and ammonia.
