yeah, legally you can't take meds out of your state. Laws are so stupid. Seriously UNITED my butt...
Soap bar idea was genius, why didn't you like that idea?
You legally can only carry 2oz bottles of liquid too. I don't think you could get on the plane with anything larger.
I know its your medicine, but the law is not on your side. It says you are screwed out of meds if you ever want to leave.
Just do this. Pre-roll all your joints. Make them look pro. Vacuum seal them in a new/emptied pack of cigarettes. Keep it in your pocket, Make sure you remove the stupid foil insert in the cigarette package, they go off in metal detectors. If they insist you empty your pockets further, then you just have to act cool when you drop you pack of smokes in the bin.
I've personally gone through airport metal detectors and xrays with a lighter in my pocket. I was stubborn and knew that past that gate, there was no way to light up. So I refused to give up my lighter and magically made it through. This was last year.
Again most likely you'd want to have it pre-rolled and vacuum sealed and in your pocket at all times.
