The just one exception I presently know of is a biotech firm, Targacept, which attempted to develop nicotinic receptor medications for ADHD/depression/Alzheimer’s/bladder issues these kinds of as variants on mecamylamine, but their prescription drugs failed in clinical trials and they had been obtained in 2015.
When I ultimately hit publish on that write-up back in November 2016, I desperately hoped that - in sharing my tale - a person else would have the courage to arrive forward.
