Finger joint studs AND mold ?
If mold is a problem in a certain environment, and molds “feed” on adhesives, etc.
Are finger joint studs more susceptible to structural damage as opposed to solid..?

Companies have been using finger jointed 908 casing on exterior door for many years. They are standard on many pre-hung doors. The joints always fail in time, I would not use them for structural 2x4's. I used some Primelock, (fingerjointed pine, primed trim boards) on the exterior finish of a house 5 yrs. ago. Many of the joints are quite visible today as the wood has swollen despite carefull painting, caulking and flashing. The joint failure seems to be due to humidity changes. I won't be using it anymore.
Fingerjoint studs are likely made using a structural glue, like resorcinol.
Door casing will likely use a cheaper, non-structural glue.
Resorcinol joints will not fail. Resorcinol is impervious to mold, fungi, acids, alkalies, solvents, etc.

Thanks for the info
We are considering finger joint studs for interior non-bearing walls...But again Storage procedures by our suppliers AND ourselves often put the wood at risk of mold.
I know we have seen disintigration of press-board due to fungi, so it raises some concern
