They will not find guns and "other drugs" at dispensaries! Not at compliant commercial ops either.
You might be right, but you hear it here and on youtube all the time. People protect their grows with guns. Some of those are "legal" growers.
As for other drugs at dispensaries, I got that part from our neighbors up north. I think I also heard about it in MI. Both Canada and MI cracked down on dispensaries. There were several reports of other drugs being found, though no specifics. So maybe a budtender had some personal use drugs in their pocket or locker and that made headlines. Who knows. But it does show you how they will spin what they find.
You are correct though, if they are "compliant" operations, they won't have guns or other drugs. That by definition would put them out of compliance.
It is all propaganda at that level. And they will maximize it.
