There's an initiative on the November ballot here in Colorado to legalize pot. It'll probably pass. We already have hundreds of pot stores here in the state, but you need a prescription from a doctor to buy pot at any of them. There's one right down US160 from my place. If the initiative passes and is signed into law, you will no longer need a precription to buy pot, and of course the state will probably collect ten times the tax revenue they collect now. And let's don't even speculate on the effect legalization will have on drug crime, especially along the border. Most of it will disappear.
As to your paranoia about having smoked pot a few times before entering the army, there's a companion option to Option 40: it's called Option keep your mouth shut. Remember it. It'll serve you well for the rest of your days.
