There is a lot of judgement being passed without all the information. The OP needs to state what question he answered "yes" to.
These are the possible reasons from the La CCW permit applic:
13. Are you an unlawful user of or addicted to Marijuana, depressants, stimulants, or narcotic drugs?
14. Have you ever been committed involuntarily, or voluntarily admitted to any treatment facility, institution, or hospital for
the abuse of a controlled dangerous substance as defined in R.S. 40:961 and 964 or for the abuse of alcoholic beverages?
15. Have you ever been adjudicated mentally deficient or been committed to a mental institution?
16. Have you ever been hospitalized for any form of mental illness or infirmity?
17. Have you ever received medical treatment for a mental disorder of any kind by a licensed medical practitioner?
18. Are you currently taking, or have you ever been prescribed any medication used for the treatment of depression, psychosis
or any mental illness?
19. Are you suffering from any mental or physical infirmity due to disease, illness, or retardation, which could prevent the safe handling of a handgun?
So, if the OP answered yes to any of these, he needs medical clearance. Why didn't he go back to the original physician and obtain documentation that he no longer suffers from any malady that would prevent him from CCW? The truth of the matter is, no physician worth his salt would sign this unless they themselves treated him and knew the patient well. Maybe some things like a handicap tag application, but not a CCW.
What if the doctor, without knowing this patient's history or having any treatment records, signed this form? Afterwards, the guy carries a concealed weapon and in a moment of anger or despair ends up pulling it and killing a bunch of people?
You folks would be writing things like, "That doctor is an idiot and is hurting our cause". Too many of you too easily cast judgment.
