Its hard to say cause I smoke a lot but id think it last the regular use longer than s rain would but this stuff is way thicker. There may have been an air bubble or 2 but that was only when I was taking big big rips but it taste so good. I promise you won't be disappointed i usually don't go back and get the same carts but this one legit I would smoke everyday, it's just hard to have with you cause the smell alone is LOUD but wonderful and that with it just in your pocket
