Design outcomes

Primary

MeasureTime frameDescription
Presence of intracranial arterial stenosis on cerebral MRA3 monthsRate on cerebral MRA the presence of cerebral Intracranial Arterial Stenosis segmental narrowing defined by at least two intra-cranial arteries compared with a cohort of non cannabis controls subjects.

Secondary

MeasureTime frameDescription
-Silent ischemic stroke on cerebral MRI3 monthsEvaluate on cerebral MRI the presence of sequelae of ischemic stroke defined by a parenchymal hyperintensity in a vascular territory defined on a T2 sequence.
-new intracranial arterial stenosis at 3 month follow-up3 monthsEvaluate a cerebral MRA at 3 months the presence of new intracranial stenosis among cannabis users, according to the prosecution or stopping use
-Reversibility of intracranial arterial stenosis at 3 month follow-up3 monthsEvaluate on cerebral MRA at 3 months reversibility stenosis present at T0 in cannabis users having stopped their consumption
