Can i smoke hash after 12 days of cornei transplant?

I would hesitate to: ... give you permission to smoke hash anytime! It is not in your best health interest. The likelihood that any harm to your corneal transplant would result from it is very unlikely. But because it is such an important surgery, and, I presume, all your hopes are pinned on it being successful, I would avoid any drugs or medications that are not absolutely needed. Good wishes:)
