Two concrete examples of this I can think of are

1) use of Psylocibin (mushrooms) assisted Congitive Behavioural Therapy for curing PTSD, depression, anxiety, etc. we have seen extremely good results from this and pharma companies could have likely pushed it much much sooner

2) Biofeedback/Neurofeedback has been around for more than a decade and is under-researched, under-insured, and under-prescribed for treatment of a lot of mental issues from anxiety to post-concussive syndrome to ADHD.

both of these can negate the need for a years or decades long reliance on SSRIs or stimulants.
