Multiple studies, have been published as early as 1980, that suggest that CBD has minimal side effects and overall is safe for consumption. Nonetheless, consumers should be made aware of any known, potential drawbacks of something you are putting in your body. Below, we discuss the findings from each recorded study and review on the safety and known side effects of CBD.
1980 Study in Pharmacology
On January 3, 1980, Pharmacology published their findings conducted during a study in which they tested eight healthy volunteers and 15 patients with epilepsy, looking at the side effects of CBD when consumed daily for a month. Their reported conclusions were as follows: ‘All patients and volunteers tolerated CBD very well. There were no signs of toxicity or serious side effects detected on examination.’
International Journal of Neuroscience
In 1986, oral doses, ranging from 100 to 600 mg per day of cannabidiol were given to 5 patients with dystonic movement disorders. In addition to recording specific benefits, this study also uncovered mild side effects of CBD such as hypotension, dry mouth, psychomotor slowing, lightheadedness, and sedation. It is also noteworthy, that during this study 2 patients given CBD in doses over 300 mg per day seemed to aggravate their Parkinson’s symptoms. Yet in 2014 a separate paper described how CBD significantly improves the lives of those with Parkinson’s disease. Research is continuing on this disease.
