TomNJVA Are they prohibitions from possessing or buying?
Both. See

Let's say a person was not using an illegal drug at the time he filled out the Form 4473, and then started using a drug a year later. Did he lie on the Form 4473?
Seriously?
I believe there has to be a conviction or positive drug test in the year prior to purchase to assume he was a user at the time of purchase, but no such requirements after purchase.
Not at all correct. Simply being a USER of an illegal drug is a prohibiting factor and says so right on the Form 4473.
Same scenario, if the person started using drugs a year after the purchase, is he now a prohibited person?
Yes.
If so, does that mean he cannot posses and must either dispose of his gun or stop using the drug, or just cannot purchase another gun since to do so would require lying on the Form 4473?
He cannot be in possession of a firearm period.
riffraff I highly doubt anyone has ever been prosecuted for lying on the form for drug use.
It doesn't change the fact that it is a Federal crime.
Denied rarely, but even those with dangerous & serious criminal records typically escape actual prosecution...
Can you cite a source for this? I think it pretty rare for "dangerous & serious" criminals with a record to even attempt to acquire a firearm through a licensed dealer....because they sure as heck would be prosecuted.
My belief as to why so few are prosecuted after a denial (and why they are never prosecuted federally like they could/should and it's only states that ever even follow up) is because the denials are so often wrong it would constantly send authorities on wild goose chases and would only serve to prove what a bad job the FBI does with this.
You make the faulty assumption that a denial means the person is prohibited. That's not necessarily true. I've had around a dozen denied transactions in the last nine and a half years.....all but one were overturned on appeal.
ATF/FBI know which persons they want to prosecute and they do.
Anyway back to the point - what they use to determine drug use are criminal convictions (ie convictions that are < 2 year max sentence so are not alone prohibiting) and they count back a certain number of years, more years if there is more of a pattern, is my understanding. Specifically 5 years clear of any criminal evidence of drug use and they are not supposed to consider it but I think dealing with NICS can be a crap shoot when it comes to this sort of thing.. Another point is you might not be lying on the form at all but they could deny you for drug use based on what I just stated.
Wrong.
Felonies or any other crime where the judge could imprison you for more than one year.
The federal government has a hair across it's ass on any drug use, seems like the ideas in reefer madness continue to live on within some branches. I do not smoke weed but could really care less if a truck driver, captain of a boat, airline pilot, etc.. smoked some weed last friday night when they were not working. To me it's as impertinent as to whether they had 3 glasses of wine but to the federal government it's a big no no and in many professions to have a license they force you into their drug test pool. Actually even for "able seamen" they force drug tests - who really cares if the mate scrubbing decks on a charter boat smokes weed anyway, well the feds do. Dumb.
Don't like the law? Then change it.
BBarn From what I've read, the NICS itself checks the buyer for violations of questions 11b-11i, 12b, 12c and a few others.
NICS checks the buyers name, etc vs a list of prohibited PERSONS, not crimes.
So the questions on the 4473 are redundant at best, and entrapment at the worst.
No, as I wrote above, it requires a buyer to answer truthfully, correct and complete. If there was no penalty for lying on a Federal form, gun stores would be inundated with buyers wanting to test the system to see if they could get a gun.
It's not anywhere close to entrapment. "Entrapment" occurs when a law enforcement officer induces a person to commit a criminal offense that the person would have otherwise been unlikely or unwilling to commit. Gun dealers aren't law enforcement officers.
Some of the questions are written in legalize and even require clarification... nearly 3 pages of them (also containing legalize) on pages 4-6.
Horsehockey.
Anyone who can't understand the questions on a Form 4473 needs to repeat middle school.
The problem with understanding the questions is the fact that 99% of buyers don't bother reading the questions, much less the instructions to those questions. Not a day goes by that I don't have to hand the form back to a buyer and ask them to give me an answer on 10a "Ethnicity.....DESPITE the explicit instructions that say both 10a and 10b must be answered.
