I bought 2 starter kits for my son and my BF for Christmas presents. Along with that I got them each 2 different juices. One 'tobacco' flavor and one flavor I thought they'd like, something fruity for her and Monster drink flavor for him. They were fairly inexpensive, maybe an option for Grandma? She can see if she likes it. I'm hoping my son and BF like it and start to vape instead of smoking cigs but in the long run, they have to do it. Good luck with it! My great grandma smoked until she was 97 and she'd listen to no one about quitting.
