Study: You could fail a drug test from second hand marijuana smoke

Second hand cigarette smoke may give you cancer, but a second hand toke from a marijuana joint could make you lose your job!

New research out of the University of Calgary might have people questioning the company they keep, especially if they work in an environment that randomly drug tests. 

In this new study, the researchers prove that second hand smoke from marijuana can lead to raised THC levels, the active ingredient in marijuana. The presence of THC in a person’s system leads to failed drug tests, even if a person never takes a puff.

Raising the THC level in your bloodstream doesn’t take long. The study, published in Canadian Medical Association Journal Open, says, depending on the strength of the strain and the ventilation in a room, all it takes is 15 minutes for a THC to be detectable in a non-smoker’s body. 

It takes up to two days for the secondhand THC to clear the system.

So, if your career requires you to be drug-free, it may take more than just avoiding bongs yourself. You’ve got to make sure the marijuana is nowhere near you.

Health benefits of marijuana

1. Parkinson's 

Cannabis has been found to help slow tremors and pain in Parkinson's patients. According to Medical News Today, the compounds in marijuana help to "reduce the effects of reduced dopamine in the brain". 

A study conducted by Israeli scientists found smoking marijuana helped reduce these tremors. "We not only saw improvement in tremor in these patients, but also in rigidity and in bradykinesia," said researcher Ruth Djaldetti.

Furthermore, marijuana has been found to slow the progression of Parkinson's because of its antioxidant qualities. 

2. Glaucoma 

The American Academy of Ophthalmology describes glaucoma as a condition in which the optic nerve is damaged over long periods of time. It can limit vision and sometimes lead to blindness. 

The link between glaucoma and marijuana has been studied since the 1970s, as smoking marijuana has been found to lower eye pressure. Doctors are working on ways to elongate the effects of marijuana. 

It has been speculated that smoking the drug can slow the progression of the disease. 

3. Chemo patients

There has been extensive research on the benefits of cannabis and chemotherapy patients. The "wonder drug", as it is hailed, does miracles for cancer patients. 

According to Dr. Donald Abrams, marijuana "is the only anti-nausea medicine that increases appetite.”

The American Cancer Society claims that the drug can also lower pain, reduce inflammation and calm anxieties of not just chemo patients, but patients suffering from a chronic illness or disease. 

Scientists have found that cannabinoids, one of the many chemical compounds found in the plant, can inhibit tumor growth. It was particularly effective in the inhibition of colon cancer. 

4. Alzheimer's

According to an article published by CNN Health, marijuana may be beneficial for Alzheimer's patients. It was found that THC, an ingredient in cannabis, blocks inflammation in the brain and "stimulates the removal of toxic plaque". 

Marijuana has also been used to help dementia patients. Author and doctor David Casarett told CNN, "I spoke to many family members of people with mild or moderate dementia who believed that THC or whole-plant marijuana was effective in alleviating the confusion and agitation that sometimes occurs."

5. Skin Diseases 

It is widely known that marijuana possesses antiinflammatory benefits, helpful to patients who suffer from arthritis and cancer, amongst many others.

A study published by the University of Colorado found that using the drug topically can alleviate pain and "may be effective against eczema, psoriasis, atopic and contact dermatitis. More and more dermatologists are encouraging the use of cannabinoid cream. 

6. Stroke victims 

Cannabis and stroke victims is an interesting topic of study for many researchers, some of whom contend the drug can "shrink" the damaged area of the brain. 

Doctors, who tested the drug on mice, rats and monkeys, believe the chemical "shows promise as a neuroprotective treatment for stroke”, according to the Huffington Post.

7. PTSD

Advocates have argued that marijuana can provide immense relief for patients, specifically veterans, who suffer from PTSD. In states like New Mexico, "medical marijuana is legally prescribed for PTSD". 

A study conducted by the University of Haifa fond that marijuana helped block the "development" and progression of PTSD in rats. But, researchers explain, that there is a critical window of what marijuana can do.
