I do not believe that there is any interaction between marijuana and the medications that you are on.
Also, assuming that you just had a routine laparoscopy
with no concern regarding infection within the pelvis (i.e. it was just a bleeding ruptured cyst
), then there is no reason that you should still be on antibiotics. The standard of care is to just give you one dose within 30 minutes of the start of the procedure.
I hope this helps!
