Suggest Ways To Withdraw From Methamphetamine Addiction

Good afternoon, I know that this isn t as serious as questions dealing with current addiction, but I recently found out that my girlfriend used small amounts of meth about 6 times over 3 months, 20 years ago. She is seemingly healthy, but this has been difficult for me to accept. One of my main concerns is that we plan on having a family and I don t know how her past experimentation could have affected her reproductive system. Or permanently affected her overall health. Again I realize that this isn t an urgent question, but I m very worried and any information you could share would at least help me understand. Thank you
