Agreed, Lithium is an anti-psycotic and treats a much different issue than the SSRI's. Also the SSRI's are not just for treating depression but used for treating anxiety as well. I think its important that this be passed because as was said before, there are most likely many pilots that are already being secretly treated. Now that its permitted they can be monitored more closely.

As food for thought you can be disqualified for uncontrolled high blood pressure but even if you go on drugs that bring it down you are still at a muck higher risk for stroke and heart attack. Those are just as serious a risk as vision problems and possibly having a seizure. What about high cholesterol problems? Im just saying that there are many things that could cause health issue for humans and the FAA is trying to manage the risks with each one.
