Who do you think is forming psychiatrist? The same big pharma that produce these drugs, obviously if the big pharma hide on purpouse how much time lasting effects of these drugs to psychiatrists, they cannot know How much time the effects are lasting.
Maybe someone know, but they hide that and try to blame a mental illness in order to prescribe more drugs (remember that the big pharma are there because of easy money, not because They really care about mental illness or helping people improve their lifes).
I’m sure that the more a psychiatrist prescribe drugs, the more these big pharma give him something in return like payed vacation somewhere or something like that.
The goal of these big pharma is to make profit, the goal of these psychiatrist is to over-prescribe drugs in order to bring profits to these big pharma, this is how it work.
Maybe out there are some that know about lasting effects but they won’t tell us nothing about because a drug dealer never go against who is providing them that drug to sell because both make profit over that.
