The problem with that is that by not having what it's supposed to have, some people's lives can be completely derailed. That's why I don't think it's worth the risk. They wouldn't know they're not getting what they need until it was far too late. I have an old friend who has been on prescription medication since high school. He has ended up in prison literally every single time he has gone off his meds. He goes into an extreme manic mode where he disconnects from reality and thinks he's Jesus, or one of his many other delusions. In his mind that means he can do no wrong and he starts doing all sorts of wrong, which leads to his arrest and imprisonment within a few weeks of him going off his meds. It's pretty crazy how fast he deteriorates.
