This is how Missouri defines "Intoxicated" - substantially impaired mental or physical capacity resulting from introduction of any substance into the body.
This is Missouri's law as it pertains to this discussion:
"Has a firearm or projectile weapon readily capable of lethal use on his or her person, while he or she is intoxicated,and handles or otherwise uses such firearm or projectile weapon in either a negligent or unlawful manner or discharges such firearm or projectile weapon unless acting in self-defense"
Make note of important language; "substantially impaired, "has firearm, AND handles/uses firearm...in a negligent or unlawful manner..."
I read that as:
1)Know my limit and don't become too impaired. Whether that is half a beer or half a keg, depends on the person. (Just a metaphor, please don't get too literal with me here)
2) I only break the law if I carry AND commit negligence or break a law, such as brandishing.
As for my opinion? I don't break laws. I educate myself of them so that like my gun, I can use them as my protection. I also know that I'm not some complete ******* EVER, let alone if I have 2 beers. Take that as you will.
BTW, I am a young CCW holder. I've been drinking for about 36 Moons now. I have never been apt to give up my concealment for any reason. It's "concealed" for MANY reasons!
