I feel badly gor those not able to vape due to old age or disabilities. Not everyone can mix up their juice. I also buy commercially made juices for speed and convenience factors. Its do wrong to deny these simple flavourings when cigarettes are freely available. Many if t hey can’t get them will undoubtedly return to smoking. Also the variance in flavours is a key in vapings effective use. I quit on a pear and spearmint flavoured e juice. I now like a peach and pineapple liquid, and change flavours often. The changes keep it refreshing and interesting, and keeps me vaping and smoke free.
