I have never heard of that as a side effect, but I guess if you're on something that you shouldn't get caught being on, that would cause fear of being in trouble... Same as if your license is expired, you'll imagine that every cop on the street is scoping you out. But actual paranoia (unreasonable fear and pessimism of things that aren't real threats, or thinking people are saying bad things behind your back, etc), is a psychological illness that isn't part of use of any AAS that I've heard of.
