Hey I'm new to the board but I used to do a ciggalike when vaping first hit the scene before it got stolen and I went back to cigs for many years. Back then I got a flavor from TW called green cow which tasted just like red bull. Beyond the 36mg nic I ordered it contained caffeine and Guarana apparently. I would hit this thing at a party once and be good all night.
I have never found anything to suggest that ejuice out there contains anything but nicotine but in those early days I remember finding b vitamins and even pharma like Cialias (vape a boner anyone?) so I'm interested to know more
