Cigarette smoking is connected with various risks and diseases, however cannabis smoke is still, at present, under a bogus appearance of no real threat or harm to others. Yet, second-hand weed can bring about an impact that cigarettes can’t: issues with memory and coordination, and sometimes testing positive for the medication in a urinalysis.  These claims have begun to be backed-up by a new study.

As the most utilized illegal drug in the world, still, this new study can provide new insight into how it works and interacts with the brain, which we haven’t really gotten for over 30 years, since scientists pin-pointed the THC element and how it affected heavy smokers.

2nd– hand Effects

Early research only provided basic info in the 80’s that showed how marijuana affected the smoker, not secondhand effects for those who aren’t smokers.  This new study tested people from ages up to 45 years old whom have smoked at least two times per week, then a separate group that did not smoke in the past six months.  This study is especially important because cannabis potency has tripled over the past few decades, so the results should be interesting.

Basically, the testing sessions provided an hour hot box session of smokers locked in a room with non-smokers, armed with high-potency weed, and normal home ventilation settings.  After the bake session, all participants, smokers and non, got tested for all bodily fluids and hair follicle.

How Baked are We?

As expected, all non-smokers stuck in the unventilated room had THC in their blood and urine samples, with further testing showing that even after four hours, they still had it in their system.  A full 24 hours later, at least four non-smokers had tested positive in the most strict measurements that some employers will use.

For the nonsmokers who got the ventilated room with fans and all, none of them tested positive for THC in any significant amount that would show up on any commercial drug test.

Rounding off this little experiment, the researchers also looked at any physical effects that the non-smokers might have experienced.  The ones in the ventilated room only claimed to feel a little hungry afterwards, which may or may not mean anything there, but the nonsmokers in the unventilated room described themselves being “happy,” “tired,” and less alert.  Testing also showed that the latter group made more calculation errors.


Needless to say, for anyone familiar with how drug trials go or any reputable health science research, this study needs to be taken with a grain of salt, even though the findings aren’t some new shocking revelation.  It’s just that nothing here is definitive and impossible to quantify in any way.

I guess, if you have your work’s drug test tomorrow, or are prone to random tests, don’t sit in a room without A/C, vents, or windows while your friends light up joints for over an hour.  What kind of nonsmoker would put up with that anyways?
