Anyone who owns firearms will tell you that it is illegal for drug users to own or carry firearms. The reason that gun owners know this is because each time they undergo a background check to purchase a firearm, they are forced to swear under penalty of perjury that they are not drug abusers. As more states legalize medical and recreational marijuana, these state laws are coming into conflict with Federal firearms laws. States like Maryland and Hawaii have recently issued guidances instructing citizens that residents who are prescribed medicinal marijuana must surrender their 2nd Amendment rights. Question e) of ATF Form 4473 -- which must be filled out to purchase a gun from a licensed dealer -- asks the respondent, "are you an unlawful user of, or addicted to, marijuana or any depressant, stimulant, narcotic drug, or any other controlled substance?" It then includes a "warning" footnote: "The use or possession of marijuana remains unlawful under Federal law regardless of whether it has been legalized or decriminalized for medicinal or recreational purposes in the state where you reside." According to Bureau of Alcohol, Tobacco, Firearms, and Explosives regulations, anyone who uses cannabis, even for medicinal purposes, is a prohibited person. They can't own, purchase, or carry firearms. If you are a marijuana user and answer yes on the form, then you fail the background check. If you lie and say no, then you've just committed perjury and opened yourself up to facing years behind bars. But the disclaimer that the ATF added to its form throws a wrench into the whole thing because it conflicts with the very reason that marijuana is banned at the Federal level. According to the Drug Enforcement Agency's own literature, "Schedule I drugs, substances, or chemicals are defined as drugs with no currently accepted medical use and a high potential for abuse." By classifying marijuana as a Schedule I drug, the Federal government is saying, in no uncertain terms, that it has "no currently accepted medical use." That conflicts with the ATF's own form, which admits that there is consensus among the majority of states that marijuana has medicinal utility. Based on the fact that doctors in 29 states are now prescribing cannabis for patients and medical journals are studying its medicinal qualities, the Federal government's blanket ban on marijuana user gun ownership is becoming untenable. It simply isn't possible to truthfully describe marijuana as a drug with "no currently accepted medical use." This past summer, I had a house fire and my cat was seriously shaken up. I took her to the veterinarian and they prescribed hemp oil to calm her nerves. If I had been caught by a law enforcement officer legally carrying a gun with my cat's prescription cannabidiol in my pocket, I would have been facing felony charges because the Federal government disagrees that non-psychotropic hemp oil has any medical purpose. Across the board, the law allows for
