I looked into grow-op houses briefly earlier this year.
The realtor that I was talking with told me two things
1.) No one can sell a house unless it has been deemed liveable byt the city. So what she told me was that if I buy a grow op house (even from teh bank) it has already passed some sort of certification saying its healthy to live in.
2.) When selling a grow house You have to disclose that it is a (or was) a grow op house.
Not only do these houses have issues with mold, but you may also find serious structural issues (Ie holes in foundation to hide secret vent pipes to sewer, holes in walls, shotty electrical wiring) You have to remember that the ruthless drug lords (lol) who were using these houses were not concerned about the resale value of the home.
1-10 grow op houes burn to the ground.... Might be a good way to make some money off insurance?? hahah
