God bless the person you spoke to who has cancer.
My husband has cancer. A new drug called Zofran (which is very expensive) controls nausea very well. Other new drugs are out there.
Turn pot over to the drug companies, and if it is useful then reguilate it like any other medicine. And lower the prices -- that's another crime.
She (my friend) said that she specifically tried two drugs for nausea and they did not work for her. I believe she said "Zofran" was one of them. The reason why the marijuana was effective for her was that it was inhaled as opposed to swallowed, and it gave her her appetite back.
