But catching a whiff of marijuana fragrance through your apartment window or entering a room where people were smoking several hours ago is very unlikely maybe even impossible to affect you at all. According to the American Lung Association , regularly smoking marijuana yourself can damage your lungs and weaken your immune system. And a study on rats showed that just one minute of secondhand marijuana smoke impaired lung function for at least 90 minutes — which is longer than the lungs are affected by tobacco secondhand smoke.
Secondhand marijuana smoke exposes you to many of the same toxic chemicals as smoking it directly does. Because of this, the American Lung association recommends that people avoid exposure to secondhand marijuana smoke. Here are some of the other side effects and symptoms of secondhand marijuana smoke exposure. If you have high levels of THC in your blood from secondhand marijuana smoke, it might have the same effect. One effect of the THC in marijuana is the feeling of calmness it gives some users.
For others, this calmness can take the form of feeling tired or lethargic. Researchers are still trying to understand the connection between excessive marijuana exposure and mental health. It appears that marijuana use can trigger or worsen some mental health conditions, including depression. Contact highs are unlikely but possible, and a contact high can impair your ability to drive and perform other tasks.
We need more research to understand how secondhand marijuana smoke compares to other types of secondhand smoke. Can you test positive on a drug test after inhaling secondhand marijuana smoke? Probably not in most cases. But it is possible to detect marijuana in drug tests after exposure in an unventilated room to larger amounts of THC, the ingredient in marijuana that causes the high.
Drug screens can look for THC in your blood, urine, saliva, or hair. In one study , nonsmokers spent 3 hours in a well-ventilated space with people who casually smoked marijuana.
Next, the researchers conducted the same experiment for 1 hour in an unventilated room with marijuana that had higher levels of THC This time, some nonsmoking participants did test positive for THC in their urine—but that was rare, and it only happened in the hours right after the experiment.

In comparison, with cigarette smoke, this effect lasted only 30 minutes. It is possible to conclude from these findings that secondhand marijuana smoke could have negative effects on the heart. However, researchers must continue to study this before making any firm conclusions.
A study into the effect of secondhand marijuana smoke on 83 children with parents who smoke found that almost half of the children had biological evidence of exposure to marijuana. Although there was no evidence to link secondhand marijuana smoke to health issues in these children, the results are concerning, given the presence of potentially harmful chemicals in marijuana smoke. Marijuana cigarettes contain various toxins and tars that are also present in tobacco cigarettes, leading researchers to believe that secondhand marijuana smoke possibly carries some of the same health risks as secondhand cigarette smoke.
More research is necessary to confirm this, though. Learn more about cannabis and pregnancy here. Current studies indicate that secondhand marijuana smoke is unlikely to affect people who experience limited exposure in a well-ventilated environment. However, researchers need to carry out more studies to determine the effects that secondhand marijuana smoke can have on a person.
It is also possible that people with asthma or other breathing issues could be more prone to negative side effects from inhaling secondhand marijuana smoke. However, there is currently no research to support this theory. In general, contact with secondhand marijuana smoke is unlikely to cause any harmful effects. However, a person who is around people smoking marijuana should be cautious, as there may be unknown risks.
Many people use marijuana, either for medical purposes or recreationally. However, can this lead to a 'weed hangover?
