Official title

Prevalence of Intracranial Arterial Stenosis in Regular Resin of Cannabis Users Compared to Control Subjects: a Preliminary Study of Feasibility

Overview

Primary outcome measures

  • Presence of intracranial arterial stenosis on cerebral MRA [Time frame: 3 months]
Secondary outcome measures (3)
  • -Silent ischemic stroke on cerebral MRI [Time frame: 3 months]
  • -new intracranial arterial stenosis at 3 month follow-up [Time frame: 3 months]
  • -Reversibility of intracranial arterial stenosis at 3 month follow-up [Time frame: 3 months]
