Why would eating a marijuana edible instead of pain pills for pain management affect my BBL results?

I am 16 days post op, I know that SMOKING can cause difficulties after surgery but what about eating marijuana edibles instead of pain pills for pain management after a bbl? I know that there is still alot of closed minded stigma around the marijuana subject and I'm looking for a non bias and honest reason why it would have any negative effects after a surgery. Also I am a legal prop 215 patient.
