INTRODUCTION: Cannabis is the most consumed drug in the world particularly in young adults. Few reports have suggested a causal role of cannabis in the development of cerebral or cardiovascular events. We describe the first association of myocardial infarction and stroke after heavy cannabis consumption in a 45-year-old woman. OBSERVATION: Stroke occurred in relation with a right carotid and middle cerebral artery thrombosis after cannabis abuse. The patient was successfully treated with intravenous rt-PA. Two days after her admission, she presented a myocardial infarction due to a coronary thrombosis. Cerebral and coronary arteries were angiographically normal. Etiological tests were negative and a toxic cause in relation with cannabis consumption was concluded. CONCLUSION: Cannabis can be associated with vascular events by different mechanisms. Thrombosis may occur in cerebral and/or coronary arteries. We suggest that it might be useful to search for cannabis consumption systematically in young subjects victims of stroke and myocardial infarction. 2009 Elsevier Masson SAS. All rights reserved.
