Well, imaginary scenarios (you carrying a 1/4#) are interesting, but in reality to remove your possible defense at a criminal trial for possession of significant amount of illicit substances would be incredibly foolhardy.
And if you're not carrying anything, you are wasting both your time and the time of the police to consent to a search. Both you and they have better things to do with your life.
And on simply a more pragmatic level, I would never consent to a search because it's frankly no one's fucking business what I have in my vehicle or in my home - especially a police officer.
The simple three word answer to a request to search is, "Of course not"
Now be careful you don't say that in response to, "Do you mind if we search your vehicle/home"?.......heh
