First thing, states are passing laws in the meantime. One or two states already won't allow elquid to be imported into their state.I haven't started stockpiling anything yet besides buying juice in larger quantities. I want to wait until the last moment to purchase the mods and tanks I want if necessary. If as suggested, this doesn't really kick in for two years.. I want to be stocking up on newer equipment. I would rather not be stuck with antiquated gear during the e-cig apocalypse.
Second thing, has anyone noticed DIY wasn't mentioned? Was it because they're not worrying about that at this point? Or, is it because they have sneakier plans?
I would, above all, stock up on nic. I vape 12 mg/ml about 30 ml/wk. One liter of 100 mg/ml would last me 5 years. You can get 2 liters of 100 mg/ml for less than $100. Since nic is the most vulnerable point (for those that do use nic), it wouldn't hurt to get a 10 year supply out of the way right away.
Basically, make a list from most vulnerable to least. Then stock up on the most vulnerable first. Even if you can only buy one or two things at a time. That way, if they catch you by surprise, you have the most essential already covered.
First thing I stocked up on was nic. It's relatively cheap and available now. Wonderful for the peace of mind!
