(7) "Controlled substance" shall have the same meaning as in section 18-18-102 (5), C.R.S.

There is no specific definition for "under the influence" in relation to CCW, as NewRacer has pointed out.
oops...got in a hurry

I'll update it later, assuming I can find the appropriate statute.

My understanding is that for the purposes of 18-12-106, the courts are applying the same standards as for DUI, but I haven't been able to research the precedents yet. Either way, it's a class 2 misdemeanor to be in possession of a firearm while intoxicated.

Maybe 18-1-804 Or 42-4-1301
