Do you need help with the product or do you want advice regarding its use? For all questions related to the products and their use, we are available by phone or e-mail.
We will also be happy to answer any questions you may have about research on electronic cigarettes, as well as on the topic of smoking cessation. Most of the team that makes up the Q Vapehouse brand are ex-smokers (some of us smoked for 25 years or more), so we will be happy to try to answer or find an answer and help you quit smoking!
For help (we speak English, German, Croatian and Slovenian), you can call us from Monday to Friday between 8:00 and 16:00.
