>>10942377From what I've read it's illegal THC carts like dank vapes, which are laced with, among other things, thickening agents not designed to be heated, let alone vaped.
>>10942044Public health England says vaping is 95% safer than smoking cigarettes. Smoke itself is a carcinogen, and smoking deposits tar in lungs. Vaping does not do this.
Vaping with distilled water is not a great idea. Not only is it unpleasant, the solvents that make up 99% of the volume of vape juices are just propolyne glycol and vegetable glycerin. The same substances found in many medicines and other things like shisha that people have been smoking for years.
It seems like the chemicals that have the worst potential for harm in vape juice are the flavorings. These are unregulated, and I havn't seen any studies showing which are healthy or not. Diacetyl, which causes popcorn lung, was common in vape juice flavors, especially popcorn flavors, before it gave people popcorn lung. More testing needs to be done on these, so I'd recommend vaping unflavored or lightly flavored juice to reduce harm. A potential problem with juul and other closed pod systems is that their liquids are flavored much more heavily than other brands.
