For $70, I think it's worth a try. I honestly think it's a great idea. I've tried every homeopathic treatment I can find to keep her around as long as possible. We are both 35yrs old. Found out she had stage 4 neuroendocrine pancreatic cancer, 2 weeks after getting married in 2011. It's been a hell of a ride. Docs swear it's her dedication to marijuana that has allowed her to live so long. She has already outlived their best estimates., Even after being given 2 weeks to live, emergency 12hr surgery and then told 3-5yrs. It's been 8. She helped get marijuana passed here in IL. MMP put us in a hotel and everything just so she could go speak in front of our state government about her journey. She's the reason I get to grow. We've bonded over marijuana over the years. She's kinda small and doesn't take well to most treatments... It makes it hard for her to take much else besides her normal meds. This ozone should help... Especiall,y since we finally got her to quit smoking cigarettes this year. Wish she would have done that years ago.
