I ran across this today. Maybe I'll not become a "Colorado Farmer".
*** NOTICE ***
By Colorado State Statute, the use of illegal drugs is a disqualifier for issuance of a concealed handgun permit. While the limited possession and conditional use of marijuana is no longer a violation of Colorado Statute, it is still a violation of United States Code. If you use, possess, cultivate or distribute marijuana, we cannot issue you a concealed handgun permit.
If you provide false information on your permit application regarding illegal drug use or any other requested information, you can be charged with perjury pursuant to CRS 18-8-503.
