I sat in on a seminar with the Cleveland Clinic and IBM as they have a partnership around quantum, and one of the big problems they were working on was using it to speed up drug discovery. I don't recall if they have solved problems completely yet, but it has sped up the discovery process by orders of magnitude.
Nothing involving quantum computing has sped up the 'drug discovery' process by orders of magnitude. At best it has 'accelerated' some toy QM problem that is likely a dozen steps removed from anything you could call drug discovery. I'd love to be proven wrong, but I've yet to see any non-trivial computational chemistry work done on quantum computers.
