Secondhand marijuana smoke and kids second hand smoke

During the same time period that cigarette smoking around children came down more than 7%, marijuana smoking around children went up nearly 5%. With more and more states legalizing marijuana for recreational use, that number is likely to continue going up.
This is not good. Besides the fact that we don’t want children getting high, or exposed to the dangers of inhaled secondhand marijuana smoke, there is the additional concern about long-term effects on the brain. While research is still ongoing, there is evidence to suggest that when youth and young adults (whose brains are still developing) are exposed to marijuana, it may have permanent effects on executive function, memory, and even IQ.

Review of the public health risks of widespread cannabis use Pregnancy, car crashes, mental health, pediatrics, Long-term, Doctors, Research, second hand smoke, smoking

1. Legalizing cannabis has been shown to increase the rates of motor vehicle accidents.
2. Cannabis use is a risk factor for mental illness.
3. Inhaled Cannabis use is a risk factor for respiratory infections.
4. Cannabis use increases the rate of vascular disease. Cannabis is the third most often identified drug of abuse
5. Cannabis use during pregnancy has been associated with increased risk of adverse birth outcomes
6. Legalization of cannabis has been shown to increase cannabis exposure in the pediatric population.
7. Heavy cannabis use is associated with diminished lifetime achievements.
Doctors must educate the public about the potential harm cannabis causes with heavy, and possibly moderate, widespread use just as they do about the dangers of tobacco use. Tobacco use has declined in the United States in large part because of the knowledge the public now holds about its adverse effects, as opposed to legislative action.

Smoking cannabis 'damages lungs' smoking, lungs, second hand smoke

Even after less than six years of smoking the drug, the ill effects were already being seen on their breathing, according the research presented at the British Thoracic Society (BTS) winter meeting.
 
"It is vital that young people understand the dangers of both cigarette and cannabis smoking since these habits can start having a serious impact on their lungs at an early stage."
 
 

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.)

Marijuana Is Not Safe to Smoke, Researchers Say smoking, Research, second hand smoke

The mold and bacteria was so widespread and potentially dangerous that the UC Davis academics concluded that they cannot recommend smoking raw or dried weed. "We cannot recommend inhaling it," says George Thompson III, an associate professor of clinical medicine at the university who helped conduct the cannabis research.

A minute of secondhand marijuana smoke may damage blood vessels American Heart Association, second hand smoke

“Arteries of rats and humans are similar in how they respond to secondhand tobacco smoke, so the response of rat arteries to secondhand marijuana smoke is likely to reflect how human arteries might respond,” Springer said.

Colorado Study Finds One in Six Children Hospitalized for Lung Inflammation Test Positive for Marijuana Exposure Colorado, second hand smoke, Children

A new study to be presented at the Pediatric Academic Societies 2016 Meeting found that one in six infants and toddlers admitted to a Colorado hospital with coughing, wheezing and other symptoms of bronchiolitis tested positive for marijuana exposure. 
"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." 

Marijuana and Lung Health lungs, second hand smoke

Smoke is harmful to lung health. Whether from burning wood, tobacco or marijuana, toxins and carcinogens are released from the combustion of materials. Smoke from marijuana combustion has been shown to contain many of the same toxins, irritants and carcinogens as tobacco smoke.4-7

The reviewers consider areas in which little research has been conducted. This includes possible health consequences of secondhand marijuana smoke; the long-term impact of prenatal marijuana exposure; the therapeutic potential of the individual chemicals found in the marijuana plant; and effects of marijuana legalization policies on public health.

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.
