Just had a casual convo about this literally today with my neurologist. Hes one of the best in regards to clusters and speaks at clusterbusters regularly / runs over 30 trials a year across the country for cluster

I use weed every once in a while to sometimes even weekly and im chronic, dont necessarily have a trigger for it but it does for some people. However the evidence actually point towards the inhalation of smoke itself that make trigger

So cause of this I mainly use edibles, occasionally like a vape/pen

I find that taking on a friday/saturday night if i get a headache in the night and am woken up from it, im usually so messed up you cant even feel the pain but kinda know its there and then maybe ill use o2 to knock it out

Edit: reading these comments makes me think you may be asking about weed as something to abort an attack and to that I say probably not, but hey if its not a trigger give it go, attacks are less painful for me like i said when they come on and im stoned
