According to studies, there is not enough data to conclude that if being exposed to someone smoking marijuana will alter your drug screen results (Dr. Barry Sample, 2018). Although the CDC, Centers for Disease Control and Prevention, states that being around secondhand weed smoke can get a bystander "high" because it still contains THC. If you want to get tested for Marijuana in your system, you can pick from urine to hair to saliva testing. Oral fluid testing is 2X likely to find THC in your system (Quest, 2018).
