Hair transplant; Does smoking pot affect hair post FUE treatment ?

There are no studies that specifically indicate that it would impact your FUE results. However, smoking of any kind can restrict blood flow which could theoretically impact your grafts. I would recommend waiting at least a month before any kind of smoking.

Smoking cigarettes will reduce your vasculature and delay healing time.  Results should still be obtained, but may be delayed in some. Anecdotally with our patients whom smoke marijuana regularly (2-3x/day) we've noticed a 1 month delay to the onset of growth but once growth occurs, the velocity of the growth catches up with non-thc smokers.
