You're ALL being a little too paranoid. I've carried on planes (and a cruise ship) well over a dozen times without difficulty. However, I will say that since 9/11 I always check my dope instead of carrying on. I usually use a small Aleve bottle or film cannister and just put it in my shaving kit. I just don't try to carry any real weight. However, I am paranoid about coming back from high profile places like Jamaica with ANYTHING. ...just my two cents.
