Most people with this diagnosis have ‘episodic’ cluster headaches, which is characterised by clusters of recurring headaches that last from 4 to 12 weeks, then several months headache-free before another cluster occurs.
The headaches themselves can last between 15 minutes to a number of hours. They can severely impact daily activities and a person’s ability to work during attacks, which can poorly impact a person's quality of life, and contribute to the development of mental health conditions like depression or anxiety.
Since its legalisation in 2018, medical cannabis and cannabis-based products have emerged as a new treatment option for patients with cluster headaches that have not been responding to conventional treatments.
This is because evidence suggests that medical cannabis can interfere with pain signals, and reduce the perception, or severity, of pain, and often, medical cannabis patients note an improvement in their quality of life after starting treatment. Medical cannabis cluster headache treatments are not suitable for everyone, but they may be able to offer relief to patients who have yet to find this response with conventional, licensed options.
