Not a direct result that I have read about but cannabis is associated with increased risk of stroke in your people.
Thank you. Just to clarify, are you saying that the ptosis would be a result of the stroke (which could be a result of cannabis use) or are you saying it could be a direct result (stroke aside)?
There are no studies on this but some of the other things reported with cannabis use including increased risk of stroke in younger people might cause ptosis especially if you also use nicotine products.
