10 Most Important Cannabis Studies Released in 2015 (So Far)

Cannabis-Flower-1Despite being far from over, 2015 has already been an incredible year for cannabis science, with numerous studies bringing forth further evidence that cannabis is an incredibly diverse, safe and effective medicine

Although it’s extremely hard to narrow it down, below is a list of what we feel are the 10 most important cannabis-related studies released so far this year. We’ll revisit this again once the year is officially over.


Activation of the endocannabinoid system – something done naturally by cannabis – can attenuate newborn brain injury caused by germinal matrix hemorrhages, which is one of the most common and devastating cerebrovascular events that affect premature infants. This is according to a May study published by the U.S. National Institute of Health.

Cannabis greatly improves the healing process of broken bones, and makes the bones harder to break in the future, according to a July study published in the Journal of Bone and Mineral Research.


An April study published in the journal Annals of Clinical and Translational Neurology found that activation of the body’s cannabinoid receptors can rescue learning and memory after a traumatic brain injury.


Tetrahydrocannabinol (THC) may prevent the rejection of organs during a transplant, according to a study published in the September issue of the Journal of Leukocyte Biology.


A study published in the journal Molecular Oncology, and published online by the National Institute of Health, found that the cannabis compound cannabidiol inhibits the growth and metastasis of highly aggressive breast cancer. The study was published in February.


An April study published by the journal Psychopharmacology found that the body’s cannabinoid receptors play a vital role in the management of social interactions and aggressive behavior, and that administration of a cannabinoid receptor agonist (meant to mimic the effects of cannabis) significantly reduces aggression.


9-tetrahydrocannabinol (THC) – the primary psychoactive compound found in cannabis – inhibits melanoma tumor growth, according to a study published in the most recent issue of the journal Life Science, and published online by the National Institute of Health. Melanoma is the most dangerous form of skin cancer, killing over 10,000 people a year.


A study funded by the National Highway Traffic Safety Administration, and released at the beginning of the year, found that driving after smoking cannabis does not make you more likely to get into a car crash.


Consuming at least one joint a day for 20 years has no negative effect on a person’s lung health, according to a comprehensive study published in the journal Annals of the American Thoracic Society, and published online by the National Institute of Health.


A study published by the Oxford journal Carcinogenesis, and published online by the U.S. National Institute of Health, has found that the cannabis compound cannabigerol can prevent the progression of cancer cells formed in the colon.


Honorable mentions:


A study published in April by the American Journal of Clinical and Experimental Urology, and published online by the National Institute of Health, found CB1R (cannabinoid receptor type 1) activiation, which occurs naturally through the consumption of cannabis, can treat pain arising from cystitis (urinary tract infection).


Daily cannabis use among U.S. college students now exceeds daily cigarette use, according to a new study conducted by researchers at the University of Michigan. Given that cigarettes are fatal and highly addictive, and cannabis is neither of those things, this is definitely a positive development, and one that signifies the acceptance of cannabis into mainstream culture.


A history of cannabis use is associated with a lower likelihood of obesity and diabetes, according to a study published in the journal Obesity.

    there’s been lots of debates on whether or not marijuana causes schizophrenia.

    It’s not true. it doesn’t cause it. I have schizophrenia and it saved my life after a suicide attempt, my schizophrenia has improved while using it over the last decade to the point where I don’t even hallucinate anymore at all not even auditory hallucinations, etc. It’s the best thing that ever happened to me for my mental illness.

    There were a few studies that recently found no link at all between cannabis use and schizophrenia even among teens. might want to mention those as well since prohibitionists are banking on causation theory now to justify keeping it illegal at least in Canada.

    I’m sick of being used as a political football to try and justify something that’s made my life a living hell. end prohibition! don’t let anyone tell you this stuff causes my mental illness. it cures it! the more people who call out this bullshit theory, the less they will be able to justify prohibition.

    I have trigeminal neuralgia and am allergic to nearly all pain medications. It is one of the most painful things possible. Their support website even has a link to a suicide hot line because the pain can be so bad that people do commit suicide from it. Pain medication has no effect on it. I use edibles and as soon as my brownie takes effect, I am able to go to sleep pain free. It is a miracle as far as I am concerned.

    I have driven under the influence of cannabis. If anything it makes you more specially aware. I also found myself driving slower than I usually would. I also found that it increased my reaction times when playing computer games. Levels I would struggle to do became a lot easier. The problems start when people mix cannabis and alcohol. It seems to make the sedative effect of alcohol pronounced, and the amount you have to consume for the negative effects to decrease. I would never drink drive. Drinking definitely has totally the opposite effect of cannabis. So why is drinking legal and smoking illegal. Tax and back handers. Just the same as the tobacco industry. Governments could save themselves a lot of trouble, and make a lot of money in taxes if they legalised cannabis and controlled it, the same way they do with tobacco and alcohol. And at the same time undercut the people prospering from its illegality. Kill two birds with one stone.
