It saved the life of woman I know during pregnancy, quite literally. She has recurrent hyperemesis gravidarum. Which is nausea and vomiting in pregnancy so persistent and strong that some mothers resort to abortion due to the pain and suffering. She was in the hospital begging for her life while the doctors were unable to help. None of the standard treatments worked for her. She had lost over 20% of her pre pregnancy weight and hadn't eaten in weeks, surviving off her own dwindling body fat and a banana bag. (I can't overstate how agonizing it is. If you're skeptical, there are plenty of mothers accounts to read) She was discharged for the fourth time, where every previous time she became so dehydrated from the lack of IV fluids that she was re admitted within a day. Finally, encouraged by other mothers success with it, she tried medical cannabis. Slowly she could actually drink water, then a day later sip some juice, another day tiny bites of crackers. She still vomited, and was still nauseous, but less intensely and could push through it more easily. She could finally eat. The baby was born vaginally, no complications and no health issues (and still so, years later).
It's just one data point, but worth looking into further.
