Flavoured e-juices except
tobacco are already banned as far as I know.
In the states that depends on where a person is located. I think a few states have banned flavored juices. In other states local municipalities banned flavored juices. While flavored juices in other states has not (yet) been banned. I haven't bought any retail
juice in many years. I DIY.
What's going to happen to the vape market in the US soon?
At this point I don't think anyone knows with 100% certainty what is going to happen to the vape market in the states. The one known certainty is "the powers that be" are very determined kill off vaping.
From my experience, there are several companies shipping gear via DHL, FedEx and UPS. However, the shipping labels show those being shipped from a private citizen with no mention of vape gear on the customs declarations. Same thing with the people who make and sell gear via Facebook. I do not foresee a day, in the future, where that will end. I suppose it could, sure, but not anytime soon.
Currently it costs nearly the same price to ship something via DHL, FedEx or UPS as it does to ship via Sourcemore (and others) with their shipping increases. Best part, with those three carriers, is the tracking information is always up-to-date and shipping is three business days.
The last order I received, from Malaysia, was shipped via DHL. Shipping cost me just over $20 USD. I recently saw someone paid $34 for shipping from Sourcemore for their regular (slow) shipping.
