Honestly I would not smoke it at all. It is a hard call to make as a grower and it feels really bad to lose all of that hard work, but its not worth risking your health, and frankly its a lesson for next time. Air circulation is king. Honestly a little too much is better than too little. One thing people often don't understand is if you see Botrytis on a cola, it has already infected the whole plant, it is just not visible yet. Often there will be what seems like deficiency signs, i.e. yellowing leaves, droopy stems and or leaves, etc. I would not risk it. My buddies who outdoor grow will cut off all of the moldy parts and infuse what is not visibly rotted with alcohol and drink it like that. However this article, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6679495/ , seems to say that inhalation of Botritys is not necessarily harmful to humans unless they are immunocompromised or have preexisting lung issues. I am not sure what the effects would be if you decided to make edibles.
No matter what you decide to do, take it as a lesson that air circulation is king. Also make sure that between grow cycles you sterilize all of your grow equipment and your grow room. Also definitely use alcohol to clean off whatever instrument you used to cut the rot off before touching another plant with it. Good luck and happy harvests!
