CAUTION: ALWAYS WEAR PROTECTIVE CLOTHING WHEN MIXING.[/h] NEVER TOUCH PURE NICOTINE OR LET IT COME IN CONTACT WITH YOUR SKIN. (IF THIS HAPPENS WASH HANDS WITH SOAP AND COLD WATER AS SOON AS POSSIBLE.) EXERCISE CAUTION WHEN MIXING TO MAKE SURE PETS AND CHILDREN ARE NOT WITHIN YOUR MIXING AREA. Nicotine is highly dangerous if ingested by children or pets. Some flavourings are known to be inappropriate for inhalation, and at least one is known to be hazardous (diacetyl) Carefully avoid any splashes and spills. Have paper towel and rinsing facilities available for immediately dealing with any splashes. Consider how you will deal with a spill BEFORE it happens. ANY INFORMATION USED ON THIS FORUM IS AT YOUR OWN RISK Caution: flavourings[/h] Food-grade flavoring compounds are, by definition, not tested for inhalation. There are likely to be health implications resulting from inhalation of some flavors, and right now we do not have a complete list of the problematic ones. At least one is known to be extremely hazardous to the lungs (diacetyl) and there is no reason to suspect it is an isolated case. Because too little is known about this aspect of vaping. VAPING UNDERGROUND cannot advise you in detail on this issue; but we do know that as well as butter-popcorn the creamy, buttery, custard-type flavours will probably entail risk even if diacetyl itself is absent (because this group of flavors has a question mark regarding safety) THERE ARE NO FLAVOURS KNOWN TO BE SAFE FOR INHALATION* and nothing in this section or anywhere else on Vaping Underground can be taken as approval of or recommendation of inhalation of any flavour. * Menthol is licensed for inhalation and can be expected to be acceptably safe as a result (but not absolutely safe as there is no such thing). Vaping Underground cannot be held responsible for any consequences of following information found on the boards. We try to remove anything that looks risky for the inexperienced but we cannot find and remove everything that may be problematic. Some advice may be inappropriate for your level of experience or resources and YOU MUST EXERCISE CAUTION. Some information or procedures may have implications for health due to the limited state of knowledge about vaping risks at this time. There is no risk-free vaping.
