If you are a patient that is concerned about how your cannabis use may impact others in your household, keep reading! Medical marijuana users or their loved ones may be concerned about something called a ‘contact high’ or the impact smoking marijuana may have upon others in the same room or household.
So, is a contact high legitimate or simply a myth? Can someone get ‘high’ from simply being around others who are using cannabis from inhaling the smoke? Unfortunately, the answer isn’t a definitive yes or no.
According to a study conducted at John Hopkins University, it really depends on the ventilation of the room. In this study, they surveyed 12 people all in the same room while half the room used cannabis while the other half did not.
In the room that did not have proper ventilation, the people who did not use cannabis did test positive for cannabis use. When there was proper ventilation, the participants did not show any positive results for THC being present.
It is important to be aware that there is a possibility that someone can test positive for cannabis use, even if they don’t inhale it directly from the source. As a medical marijuana patient, you may prefer to medicate in a well-ventilated room away from others if they are concerned about inhaling the smoke.
