London, United Kingdom: The oral administration of the non-psychotropic cannabis plant constituent cannabidiol (CBD) is safe and well tolerated in humans, according to clinical trial data published online by the journal Current Pharmaceutical Design.
Investigators at Kings College in London assessed the physiological and behavioral effects of CBD and THC versus placebo in 16 healthy volunteers in a randomized, double-blind, crossover trial.
Investigators reported that the oral administration of 10 mg of THC was associated with various physiological and behavioral effects – such as increased heart rate and sedation – whereas the oral administration of 600 mg of CBD was not.
They concluded, “There were no differences between CBD and placebo on any symptomatic, physiological variable. … In healthy volunteers, THC has marked acute behavioral and physiological effects, whereas CBD has proven to be safe and well tolerated.”
A previous review of the use of CBD in human subjects, published in the scientific journal Current Drug Safety last year, similarly concluded that the compound was safe, non-toxic, and well tolerated.
Separate investigations of CBD have documented the cannabinoid to possess a variety of therapeutic properties, including anti-inflammatory, anti-diabetic, anti-epileptic, anti-cancer, and bone-stimulating properties. In recent years, patients in states that allow for the use of cannabis therapy, particularly California, have expressed an interest in plant strains that contain uniquely high percentages of the compound.
Cannabidiol is presently classified under federal law as a schedule I prohibited substance. Such substances are required by law to possess “a high potential for abuse,” “a lack of accepted safety … under medical supervision,” and “no currently accepted medical use in treatment in the United States.”

If and when the day comes that the headlines read “Cannabis Cures Cancer!” there are going to be a lot of angry people who have lost loved ones to that disease. People who maybe wouldn’t have died if we had known . . .
