I meet some guy I was a grad student with he tells me he is working on cures for cancer at his startup and I think he's a Poseur, now if he was working to cure Tourette's syndrome I'd take him seriously.
Joe Biden has a personal reason to advance Nixon's "War on Cancer", but let's see a government or private effort to cure chronic pain -- it is such a tragedy to see people dying left and right from opioid addiction which comes from a lack of safe and effective treatment for non-cancer pain.
You can go after it after the fact with addiction treatment, law enforcement, etc. but it is much better to catch that horse before it leaves the barn.
