Thanks to all who have responded! I thought that it only had dilative effect, but apparently some research suggests that it's more complicated. I'll copy a few lines from a NIH link, and share the link. Oh and I am not looking to use it for CH, I'm wondering if there are strains less likely to add to my overall headache burden, so I can consider it's use for arthritis-related issues. Experimental studies specifically targeting cannabinoids' effects on the cerebral vasculature are rare. There is evidence for transient vasoconstrictive effects of cannabinoids in the peripheral and cerebral vasculature in a complex interplay of vasodilation and vasoconstriction. https://pmc.ncbi.nlm.nih.gov/articles/PMC5986896/#:~:text=Experimental studies specifically targeting cannabinoids,interplay of vasodilation and vasoconstriction.

Greetings! As I have become more aware of the positive impact of vasoconstrictors on my clusters, I've begun to wonder about the use of cannabis, it's constrictive or dilative effects. Some time back I attempted to use cannabis to help with body pain, and it did help but also seemed to create other headache pain. I ask not to find out about cannabis use for CH, but wondering if there are strains of cannabis that have a more vasoconstrictive effect, and if that might help reduce additional headache burden while trying to manage osteoarthritic joint pain.
