He has recently gathered the views of health professionals and reviewed data of vigilance in order to assess potential risks.

thirty of the most affected

Overall, men in their thirties are the main affected, with most often a chronic exposure, as well as a frequent consumption of tobacco, or even alcohol. For more than one in five patients, the use of cannabis was ” referred autothérapeutique “, including anxiolytic, sedative and hypnotic.

With respect to cardiac disorders, which were found in 7.7% of cases, they typically take the form of tachycardia, palpitations and sometimes heart attack.

Over a hundred deaths
