No one is talking about carrying while intoxicated (whether with cannabis or anything else). We are talking about being denied a carry license, or even the right to own a gun, because you have a prescription to use cannabis medicinally.
Do you believe, then, that if you are prescribed any medication that has alcohol or opiates in it, that you should have your carry license revoked and/or your guns taken away? How about if you buy a case of beer at the grocery store?
Let me clarify, as my original "I agree with Bushmaster" was too curt and not 100% accurate. After looking back at his port, I see that he was saying they shouldn't be able to have a permit. I disagree with that. To me this is like saying that if you drink, you can't have a driver's license because you might use them at the same time.
What I do very much believe that anyone using weed, or other medications that impact ability or mental function
SHOULD NOT carry a weapon. Note, I am not saying they should not be able to get a permit,
unless they are unable to function without the medication. If they cannot function without medication that diminishes their mental faculties, the I do believe a carry permit should be denied.
I had major spinal surgery 17 years ago (laminectomy and discectomy at L4-L5, and fractures in the discs around that area), and was on morphine, followed by Percocet, then later Darvocet and finally Vicodin for a very long time, before and after surgery. While thankfully I am now back to about 90% mobility, I have not needed pain medication for 15 years. I fully remember however, the effect continued use of those medications had, on both judgment and abilities. I was, in no way, safe to be carrying a weapon then. Here in the People's Republik of Illinois it wasn't an issue (since we had no hope of CCW then), but nonetheless, I would never have even tried to apply were it available. And I would have supported not granting said permit to me based on my condition at the time.
Basically, if you choose to go out and carry, you should forgo using those meds (or medical weed)
while you are carrying. And you should forgo carrying for however many hours/days afterwards until you are no longer under the effect of those meds.
If you make the abominably poor decision to carry while under the influence of weed, Morphine, etc, I believe that you should be charged with negligence and/or public endangerment if you are caught. When you are impaired, you are a danger to the community, and should be 100% responsible, civilly and criminally, for your actions.
