I bought a good quality vape pen with some good quality vape juice (10mg nicotine). This has completely replaced my desires for smoking tobacco and really helped with the craving for smoking and vaping cannabis. It also makes me crave sweet snacks far less, less sugar in my diet. Of course there's no 'high', but it feels pleasant and the sight of the water vapour is calming, plus no smell or burning so can use indoors.
