https://www.e-cigarette-forum.com/f...g-tobacco-and-changing-to-an-ecigarette.3305/ In my opinion a great resource for the forum. I know it's another forum so if inappropriate feel free to delete. "This post has become a useful reference for tobacco withdrawal symptoms and notes on intolerance to e-liquid ingredients. It has been continuously updated as new information comes in, and will continue to be edited as necessary. The material performs several functions: 1. It ensures that symptoms of smoking cessation are not attributed to e-cigarette use. 2. It lists a wide range of tobacco withdrawal issues, which are hard to find in one place. 3. It lists ecig refill liquid intolerance issues and helps with their identification and avoidance. 4. It does not shrink from sensitive or contentious issues, and lays out all the information we have. The effects of smoking cessation are wide-ranging, occasionally long-lasting, and may not occur for a month or more after quitting. Such symptoms are well-known and widely reported, and these cannot be attributed to e-cigarette use since they are experienced by those who have never even seen one. Apart from dry throat and similar effects, almost all 'symptoms of e-cigarette use' are the result of smoking cessation and are experienced by quitters regardless of whether an ecigarette is used or not. A small number of people are intolerant to one or more ingredients in e-liquid and this is discussed below. There are also some individuals who have specific issues regarding e-cigarette use and we need to flag up such matters. This article has been regularly reformatted but would not have the useful history that it does, without the original post and the effort that was placed in it. A heartfelt thanks to the OP, bghouse, for starting it out back in 2008. For update history, please see foot of article. Please note that this section is regularly updated when new information is received."
