Point 2, off topic:
There aren't really "illegal drugs" out there. There are "controlled substances" that you must meet a variety of conditions to possess or use. Otherwise, you are illegally possessing/using that substance.

Statistically, the group in any state that is less likely to use firearms in a manner that would be considered "illegal" are those that possess a CWL/CHL license. Yep, they tend to be people who've gone through some sort of training (from small to large amounts), a background check which includes fingerprinting and a photograph. See Guncite.com and other sites, like rkba.org for vetted information on these and other issues.
Not statistically, the people who I know that are CWL holders are very aware of the consequences of using their firearm/weapon. They will leave their weapon at home/locked in car if they are planning to drink. They are often the designated driver too, since they won't be drinking when they are out with their buds.
Apply for a CWL. See what you have to go through. Get the license. Find out for yourself what is involved with the process to get that little photo ID. You don't have to get the gun, but at least you can get a valid basis to judge from, especially when you see who takes the various courses with you.
I've tried both...carrying a firearm and not carrying one. And you know, though this is personal experience (echoed by others) speaking, I am a much more responsible, knowledgeable citizen. I shoot with police officers at the range. FBI agents. And we talk weapons and other things. And I'd have to say they are all pretty agreed that someone who has a CWL is someone who takes what they do seriously and is generally a "respectable citizen."
Try walking a mile in a CWL's moccasins and see how it opens your eyes.
