Is someone who's been to a methadone clinic precluded from being licensed as a RN?

I have a friend, Sue, who was trying to become a physician istant, and was ready to enter a program this fall. Then, another PA told Sue that she might couldn't get a license b/c she had been to a methadone clinic in the past. The state board of medicine (WV) said that it was possible that she could find herself unable to be licensed after graduation. So, she decided to apply to a nursing program, but has not been able to get the state nursing board to answer her question. Also, I don't know if it matters, but Sue does have a medical condition for which she was prescribed narcotic pain relievers. She sought the help of a methadone clinic after developing a dependence on the pain pills, and then entered a Suboxone program to get off the methadone. She's very distraught that she may have irrevocably ruined her life by trying to get help, and needs to know ASAP whether she can enter a nursing program or not.
