Well, it's the decision to enforce the PACT Act, being that the Act itself has existed for quite some time now.
It has been around for a long time. I remember buying snus and paying shipping of $5 then all of a sudden there's PACT and shipping from Sweden is now about $40 depending on the amount you order. It has forced us to order a couple times a year and keep the majority in the freezer just like we are doing with nic now. I'm just thankful that I was able to stock up before all this stuff kicked in on nic and ecigs.

TL;DR: tank your batteries out of your mods if you are not going to use the mod for a while.
I want to stress the importance of never leaving a battery in a mod long term. The most common reason is "quiescent drain". Quiescent drain is the voltage your mod "robs" from your battery when it's "off'. A mod is not really "off" (unless it has a kill switch), it's just in standby waiting, listening for that signal to turn on and get to work. That takes a certain amount of current to run in standby mode, some mods will have more quiescent drain than others. Some Yihi chips are really bad about this and Yihi has refused to fix the issue. I actually vented a battery 2 times leaving it in a mod.
But the real reason is why I'm posting this - corrosion...
I had to go out of town about 4 months ago and took a bunch of gear with me. One mod, my oldest Pico 75W, I left in my backpack this whole time with a battery in it. I thought I took the battery out, but apparently I was wrong. When I went to go get it tonight, the battery cap wouldn't budge so I had to get pliers to screw it off. The battery was OK, it still had charge of above 4.0 but not quite 4.2. I used that mod when I was out of town that day so I would say it lost extremely little charge. So that's good in terms of quiescent drain on the Pico 75W.
But the reason the cap wouldn't come off is because there was this white corrosion all over the battery cap threads and the threads on the body. This definitely wasn't there before. It's a really hard, white, kind of powdery-looking stuff. And it doesn't come off with 91% rubbing alcohol. The mods works despite the corrosion.
This was obviously due to the battery being in there for too long. I can't think of what else would cause that. But I don't know what this white stuff is, either. It's not on the battery contacts at all. The battery is fine and it's clean. Samsung 25R Green.
This is the same corrosion I saw someone else post a pic of on their Pico battery about here a year or 2 ago. I believe it was @englishmick. His was was really bad and it was the whole way down the battery tube IIRC. Mine isn't nearly that bad at all. Maybe he he can post that pic here if he still has it (if in fact is was him). It was originally posted in a different thread, I think.
Tomorrow I'm going to try soaking the cap in vinegar and I'm reasonably confident that will take care of it because I've used a vinegar soak to remove rust a few times. The threads on the mod will be a bit tough since I can't soak that in vinegar without completely disassembling the mod, which I have done before a few times. The screw heads are a little stripped and I had to rig the button a bit as it lost it's soft clicky feel that Picos have. So I'd prefer to leave it alone in that regard as the button works like new now. Without being able to soak it, it'll never get those threads 100 % cleaned.
Maybe tomorrow, if I'm not feeling lazy, I'll snap a couple pics before I try to clean it.
Not a big deal as I have other mods to replace it. The reason it bothers me is mostly because I want to see how much longer this mod will last without me doing stupid crap like this. It's about 5-6 years old and was used heavily for at least 4 of those years. Other then the now-fixed fire button, it has a dimmer screen than it did when it was brand new.

That's an electrolyte material deposited from the battery that's dried up, left in powder form. I found my old high school T-85 graphing calculator a few years ago sitting in a box. It takes 4x AAA's. I tried turning it on, but no power. So I flipped it over and popped the back battery door open. The entire inside was coated and cemented in with that white powder. I'd experienced this earlier in life several times with flashlights, remote controlled cars, toys, etc., and learned to take batteries out of the stuff I wasn't using. I'd been using my graphing calculator so much in the past few years that in my head, I didn't think I'd ever stop using it. I did. The white powder will turn green if it sits, leaking for a suuuuper long time. This is what Panasonic says about it:This is important and applicable to stocking up and maintaining your stash.

So yeah, removal of the batteries in unused mods is highly advised for the sake of the mod and the batteries. I will however mention, as you have Junkle, that it won't necessarily render the mod or whatever product this happens in useless, but it certainly isn't good for it. I'd also keep an eye on the condition of the contacts and any other metals inside or near the battery harness.
I can't remember,is the cap on the Picos aluminum?If so,it could be heavy oxidation.I left the screw in drip tip adapter in my Billet box clones which are aluminum for a few months,and they oxidized so badly I thought I was going to ruin the threads trying to get them out,it was a thick white hard powder as well,and like yours,won't hardly come off.This is important and applicable to stocking up and maintaining your stash.

You already opened a thread about this topic here:
Man shares why he feels disposables are dangerous and are addicting non vapers/smokers
Fail to see how this topic is related IN ANYWAY to the title of this thread...
These are li-ion batteries, not alkaline,
The white stuff on the threads is powdery "looking", but not powdery at all like Alkaline battery electrolyte, which is very powdery and fluffy. What's on my threads is so hard you have to scrape it off with a lot of effort. It won't rub off and even 91% IPA won't clean it at all.
And it isn't on the battery at all (unlike when an alkaline battery leaks), merely on the threads. The battery is super clean and above 4v. When alkaline batteries leak, they tend to get get bloated. That isn't the case with my Liion battery.
I just got up, but I'll post pics later.
Stainless Steel, without a doubt. Same with the threads on the mod. These threads would not have lasted me 5-6 years if they were anything other than SS. Plus the sound of the battery cap when I drop it is a dead giveaway it's SS.
True - I guess in my head, there is likely some similarity in how they're built and function, but that probably isn't the case. I did find this though on an article that breaks down the workings of the Lithium Ion battery:
And from Lithium hexafluorophosphate wiki:
Still serves as an electrolyte.
I would keep an eye on that battery and see if you notice any performance degradation.

There is a type of corrosion that is caused by a negative potential alone. No current flow required for it to occur. And it is unrelated to the type of battery. Flying radio controlled gas aircraft we would have a battery pack that we would plug in and we also had a power switch to feed the radio and servos. Even if you left the battery pack in for months with the power switch off, the negative wire from the battery to the switch could corrode. It was usually on the switch side. But if you had taken the battery pack out before storage, it never happened.
It's funny about leaving batteries in mods. Having over 100 mods (most are DNA), I would say about 20 of them have batteries in them with a charge. So far, I had no problems (knock on wood). Some like the MPV2 has a lipo that is soldered in. I can also think of about five 3 cell DNA mods that still has three 18650s in them. But even still, it is a good idea to remove the batteries if you can.
