It's illegal, so you have to take that chance, did it myself at a time when it was cool, (so I thought). Only once, but now they mix it up with stuff that can kill you, not worth it in my mind. And the other problems --wanting to get something that gets you higher,. And health issues, lungs, blood, etc. Also, there are other things that can relax you without drugs, I would try them first and try to help your girl see the real light! Or maybe just move on!
