Cannabis: Considerations Before Use

Cluster Attacks Responsive to Recreational Cannabis and Dronabinol

Pharmacological preparations of cannabinoid compounds have a variety of therapeutic uses in medicine, including different pain syndromes, but have not been previously reported as beneficial for cluster headache. We present a patient with cluster headache who was refractory to multiple acute and preventive medications but successfully aborted his attacks with recreational marijuana use; subsequent use of dronabinol provided equally effective pain relief.

Functional magnetic resonance imaging in episodic cluster headache

We have investigated the cerebral activation centre in four patients with episodic cluster headache (CH) with functional magnetic resonance imaging (f-MRI). The patients underwent MRI scans for anatomical and functional data acquisition in the asymptomatic state, during a headache attack and after subcutaneous administration of sumatriptan. Anatomical images were acquired by means of 3D-MPRAGE sequences and f-MRI images were obtained by means of echo-planar imaging.
