Do nothing but? Yeah we'd be better off if people didn't buy those products, no demand no supply.
OTOH, I know several people who have been able to use vaping to drastically reduce or eliminate their smoking tobacco, and taper off their nicotine consumption.
Sidebar - that annoying cloud of vapor is visual feedback that the unit is working, it helps regulate the dose, and gives a sense of doing something when someone has gotten to the zero nicotine level, but still hasn't quite quite quit going through the motions.
What we have here is a situation where millions of people are making themselves into lab rats, vaping substances where no one really knows what the consequences will be. There likely are many who use this technology to help themselves give up cigarettes but they are the exception not the rule. Most are like my sister-in-law who suck on both all day long... cigarettes for the nicotine and the vaping device for THC at least in this liberal enclave.
I was just thinking as we were buying cigarettes for her at grocery and drugstores, that one would think that reputable retailers would not sell something that they know does nothing beneficial and causes death and disease for most of the people who use them. But “reputable retailers” are also the exception and not the rule these days.
We used to have liquor stores in this state and now they sell hard liquor in every grocery store and just about every other type retail outlets as well. The liquor stores had a bit of security and people under 21 could not go in.
I was at the self checkout at the Fred Meyers store near our house. Kids set off the alarm as they ran out of the store with their arms full of booze. The alarm went off automatically after about 5 seconds. The clerks didn't even pause the conversation they were having about how they don't get paid enough. I asked if they were going to do anything. They said that was against store policy. I asked if they were going to call the police. They said the police didn't like to be called because it happens so much. I asked if maybe the booze aisle should be located further from the door. They said they didn't want the kids knocking down other customers as they ran through the store with their I'll gotten gain.
So the store is teaching young people how easy it is to get away with criminal activity and supplying them with alcohol. I call that irresponsible. I gave one of the managers hell about it. It was like talking to a stone wall. But since that time they have moved the booze aisle further from the door, obviously because they were losing so much merchandise and not because they give a rats ass. And maybe I am not the only one who complained.
