Anyone on probation or parole better think twice about getting exposed to second-hand pot smoke, because that contact high will result in a dirty piss test. A new study conducted by Scientists shows that second-hand smoke from potent strains of weed can lead a person to test positive for the drug in urine analysis.

An individual who is a non-smoker and gets exposed to marijuana smoke in a confined space could also experience impaired memory and coordination according to a new study.

‘Many people who are exposed to second-hand cannabis smoke, can have the same test result as if they smoked it directly,’ says Dr Evan Herrmann, lead research author of the study at Johns Hopkins University School.

“The scenario we looked at was almost a worst-case scenario, but it could, in fact, happen in the real world. However, it couldn’t happen without him or her being aware of it,” according to the senior author of the study, Dr Ryan Vandrey.

‘We discovered positive drug effects in the first few hours. In addition, we found that the participants experienced a mild sense of intoxication and impaired their cognitive performance,” claimed the senior author of the study, Dr Ryan Vandrey.

Although the effects were minor, some of the participants failed what was the equivalent of a workplace drug test. The study is the most comprehensive in-depth research on the impact of second-hand marijuana smoke since the 1980s.

The original study showed the cannabis active ingredient, tetrahydrocannabinol, or THC, and other by-products present in the bodies of non-smokers bodies for at least an hour or more. Test levels depended on the amount of time a subject spent in extreme conditions with heavy smokers in an enclosed environment.

Seven cannabis smokers ages 18 to 45 who smoked at least twice per week took part in the study and tested positive only for THC and negative for other drugs.

The studied also tested 12 other subjects in the same age category who hadn’t smoked weed in the past six months and tested negative for cannabis, other types of drugs including alcohol.

In two separate experiment sessions, scientists had Six smokers and six non-smokers sitting side by side for an hour in a 10-by-13-foot, acrylic-walled room.

To their delight, each smoker was given ten potent strains of cannabis cigarettes to smoke. One session had the room’s ventilation fans turned on; the other fans were turned off.

At the end of the session, the analysts tested the THC levels in smokers’ and non-smokers including blood, urine, saliva and hair during different time intervals.

The six non-smokers exposed to cannabis smoke for the hour in the unventilated room tested positive for THC in their urine and blood. One smoker had detectable amounts of THC in his urine four hours after the cannabis exposure.

At intervals between two and 22 hours after the test, four of the six non-smokers tested positive for THC in their urine at a lower cut-off sometimes used in commercial drug testing programs.

However, None of the non-smokers exposed in the ventalated room had a positive test results for THC.

In addition, Non-smokers exposed second-hand smoke in the ventilated rooms reported no effects besides having a little bit of the munchies.

The subjects in the unventilated room reported feeling tired, more ‘pleasant,’ and less alert.

When the non-smokers were asked to partake in testing involving duplicating grid patterns and performing a basic numbers drill. Researchers discovered the nonsmokers in the unventilated room had a quicker response time but made more errors than before their exposure to cannabis smoke.

‘The behavioural and cognitive effects were minor and consistent with a mild cannabis effect,’ Herrmann says.
