Smoking Marijuana 3 days after FUE transplant??

Smoking is not recommended after surgery.  This includes smoking marijuana.  If you are concerned, don't do it.  

You should wait a while longer. There's no study to confirm it but smoking causes constriction of blood flow which certainly won't help your transplants. Marijuana is probably not as detrimental as cigarettes but again there aren't any studies that confirm this. I would recommend waiting at least a month when your grafts are essentially identical to your natural hair, just to be on the safe side.

       
In
general smoking is not a healthy vice to have. Smoking will decrease the oxygen
blood levels and decrease blood flow to a healing wound.  We recommend patients refrain from smoking 3
days prior to surgery and hold off for a week afterward.    Your
hair grafts will thank you!!!!

I would not recommend smoking anything for at least the first week, as your body is healing after transplant. You decrease the amount of blood flow and oxygen that goes to the grafts, which can lead to poor graft growth. We don't yet know the effect of marijuana on hair growth, and you just made a big investment! It's not worth the risk. 

I agree with Dr. Rassman -- there are no studies so we can't tell you for sure.  What I can tell you though is that anything that may make you cough will increase the pressure in your scalp and could potentially dislodge the grafts.  You are making a big investment in your hair -- don't screw it up!
