Hi, welcome to the forum. That is a really difficult and complex situation, but you are not alone. Unfortunately, there is not much you can do until she is truly ready to quit. Keeping yourself sane may be the priority. There is a forum on sober recovery for friends and family members of addicts. I am not familiar with Nar-anon, but I have been to several Al-anon meetings where folks are dealing with very similar situations to what you describe.
