Marijuana

Results from a trial testing the effects of CBD oil on symptoms of pain and distress in cancer patients suggest the popular product may be no more effective than a placebo, adding to an inconclusive body of research on the effects of cannabis for pain.

New research has reported on the consequences of feeding dairy cows commercial hemp. Despite the hemp containing negligible levels of psychoactive THC the researchers detected significant behavioral changes in the animals and levels of THC in their milk.

The results of a fascinating clinical trial challenge popular assumptions regarding "safer" strains of cannabis. The research found higher levels of cannabidiol (CBD) do not negate any potential adverse effects from smoking cannabis.

New research has estimated legalization of cannabis over the past 25 years has cost pharma companies billions of dollars in lost sales. And, if cannabis were to be legalized across the entire US, pharma stocks could rapidly drop by over 10 percent.

For almost a century, popular culture has presented images of lazy, unmotivated "stoners" who do little more with their lives than smoke cannabis, but across a series of lab experiments and brain imaging tests a new study is busting that long-held myth.

A robust new study led by researchers from Stanford University has found THC can trigger inflammation in blood vessel cells, and the researchers call for medical marijuana users to be aware of potential cardiovascular risks.

Delta-8 THC is similar to its commonly known psychoactive cousin, delta-9 THC, and new studies are offering the first large-scale insights into what kinds of effects people are experiencing with this unique and under-researched drug.

A new study has identified a pattern of brain activity that seems to correlate with impairment from cannabis intoxication. The researchers suggest this novel brain-based biomarker could be a way to accurately measure THC impairment.

A study is outlining strategies that should be employed by cannabis growers to mitigate the plant’s ability to absorb heavy metals from soil. The study indicates it is possible cannabis contaminated with heavy metals could lead to chronic diseases.

A study has found epileptic children treated with whole plant cannabis products displayed reductions in seizure frequency. The researchers call for clinical trials to test whether whole plant products are better at treating epilepsy than CBD alone.

A new meta-study has concluded blood or saliva THC concentrations are not effective ways to measure cannabis-induced driving impairment. The findings indicate impairment tests should be developed instead of looking to develop a marijuana breathalyzer.

A study is offering one of the most comprehensive investigations ever conducted into the origins of cannabis' unique “skunk-like” smell, discovering an entirely new family of sulfur compounds that are chemically similar to compounds found in garlic.
