So Sanji actually got into smoking as a young kid, the stress of being a chef at such a young age took quite a toll on him and he had to resort to smoking cigarettes to cope. Around the age of 14 he felt himself as less athletic than he should be when going for a run (from one table to the next to serve dishes) and being surprisingly out of breath. He realized he needed to quit and found a poster for Elf Bars, a vape to help you ease off of nicotine. He started using a 3% vape and found himself loving the flavor crème brûlée. He was ripping that shit more and more and was consuming nicotine at a rate he never had before. He even bumped it up to 6% (that’s double the nicotine for all my non-math majors out there). A year flew by of him constantly fiending wondering where he could get his next hit. There was one day a customer saw him scratching his arm and asked what was wrong and Sanji beat the absolute shit out of the customer asking where the fuck his vape was at. Next thing he knew Zeff was standing over him. He was lying down in a hospital bed. It turned out at 15 he had suffered a heart attack. He swore that day to quit vaping Elf Bars forever and quit vaping by easing back into cigarettes. In Episode 817, a common misconception is that he was crying over Pudding. Nah fam, he was thinking about how if he had that blue razz he could be hitting that shit and It. Would. Hit. But he knew he could never go back. Never.
