I use Aqua-tine when I'm stuck somewhere where I can't smoke or vape. Each packet contains the same amount of nicotine as 1 regular cigarette when smoked. There are no starter kits, no batteries, no chargers and not even any matches. Just carry a few packets with you wherever you go.For Nicotine Relief, I take two packets and add them to whatever I am drinking at the time to get thru the moment without smoking or vaping. I have two friends who ended up quitting smoking completely with it. At Starbucks I’d put two packets in my coffee for a S'Mocha Latte so I wouldn’t have to go outside to vape. It's an excellent pick me up as well as a time saver!
