I don't recall the specific stats, but remember reading where the number of times someone was actually prosecuted for lying on the 4473 was minuscule. In theory, every NICS denial could have resulted in at least an investigation if not charges.I've always thought the reason the liberals/democrats have pushed so hard for legalizing marijuana was to reduce legal gun ownership. If you admitted to using drugs/marijuana on the 4473 you could not buy a gun. If you lied on the 4473 and were caught then it was a felony and then you couldn't own guns.
