Cannabis may increase stroke risk

Young cannabis users could be at an increased risk of having a stroke, a recent Spanish study suggests. As the BBC http://www.bbc.co.uk reports, Spanish researchers detailed the case of a 36-year-old patient, with no known risk factors for stroke, who had three following cannabis use. The paper, which was published in the Journal of Neurology Neurosurgery and Psychiatry, said the risk may have been underestimated. According to the Spanish researchers, it is possible that up to 15 other cases of stroke may be linked to cannabis use. They have called for further research to establish the actual extent of the risk. Up to now, frequent cannabis use has been linked to behavioural abnormalities and an increased risk of schizophrenia.
