...anyone here ever have to work side by side with one of these dope fiends.
Sure have, three of them that I know of. Each is well-educated, talented, and professional. They use cannabis in various forms to relieve the pain from serious injuries, allowing them to eliminate or greatly reduce their dependence on addictive, destructive (legally prescribed) opioids. I work in the mechanical engineering field where you don't find a lot of dumb, wasted, lowlifes by the way.
One person I'm very close to is an RN working in a very busy valley ER, who also teaches nursing, and she helps save lives every week. She got a card to help (greatly) reduce the amount of (legally prescribed) opioids that she was taking, and it was a Godsend. She has degenerative disc disease but still works to support her family. She works sober through her 12 hour shifts (in extreme pain) because she will not use any type of drug and go to work under the influence. When she gets home, using cannabis products gives here instant relief, without being wasted on (legally prescribed) hard drugs.
Note that I said HARD drugs. There are opioids being prescribed out there, that are as powerful, and even more powerful, than heroin. They are over-prescribed, because of a flawed system that incentivizes their prescription. We have a serious opioid crisis in America, that is wrecking our country. Those who legitimately benefit from cannabis and who avoid being part of that opioid crisis, are doing themselves and their community a service. So let's separate THOSE folks from the "other" group.
By "other" group, I mean the millions of males in their early 20's all suffering from "chronic pain" who really just want to sit around being a stoned loser. Yes, many of the "card holders" fall under that category. It's very hard to say who is and who isn't exaggerating the pain they claim to have, so our system errs on the side of caution, allowing some to sit around stoned, doing very little in life except for getting by. It comes with having a legal pot program, and it is what it is. Could authorities do a better job of screening for who gets a card? Probably, but that's another topic. Should the government really be stopping people from smoking pot when they allow the same people to drink booze and smoke which both cause their own serious problems that hurt society in their own ways? That's another discussion with strong arguments on both sides.
My point is this...there are people who truly benefit from these programs, in ways that make their lives, and the lives of their family members better. I say this as someone who doesn't use any illegal drugs, and who dedicated most of last year to shutting down a meth and heroin house on my street that was wrecking our community. Many of the customers of this house ended up on heroin after failing to get enough legally prescribed opioids by the way (very common scenario). I spent a lot of money and time, and my family incurred a certain risk level, to shut that drug operation down. I am far from a "legalize drugs, and everybody party" type of guy. Things in life aren't always as black and white as some want to make them.
