Certainly there are more generic addiction programs across the country that support families of people living with addictions. I'm not aware of any that are specifically focused on the loved ones of people who use methamphetamines. There are certainly family support groups, either formal ones through treatment centres, or the classic ones that follow a 12-step program that supports family members in that situation as well. Again, there are a number of different options. It depends on what resources are available in your community.
