Here (Minnesota) they’ve basically entirely switched to disposables. So while liquids exist, they’re almost always 6%. I *really* dislike that the bottom nic level is still 3%. That makes disposables as hard to quit as cigarettes. When I removed nicotine i went by single digits down to 3, and fractions thereafter. I think the lowest number was .25. This can be done by mixing your own, or mixing store bought zeroes with identical 3% flavors. (Which you generally have to order online. I think I’ve seen a total of two bottles of zero in stores. Most places none) It cannot be done at all with disposables though, and I think that makes them the worst system by itself.
