Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF OCTOBER 19 2025
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

I seriously doubt that, because the bases in e-juice were studied thoroughly in the 50's with no such evidence.
And nicotine has obviously also been studied thoroughly, and the nicotine is not considered a major carcinogen in cigarettes, it's mostly compounds created by the burning of the paper and tobacco that cause cancer that is the actual SMOKE in smoking, which vapes do not have, unless the vape is seriously overheated.
I bet that this study is flawed, if it truly shows indication of cancerous effects, I bet it's because they overheat the e-juice, which has the same effect as burning fat on a frying pan. And with the e-juice taste horribly.
Either that or they've used impure products, and not the pharmaceutical quality products that dominate the industry.
If you are a vaper, make sure the nicotine and base juice are both pharmaceutical quality.
This is partially based on self reporting, which is the least reliable form of study there is.
Also I've never heard such warnings from dentists?
Unfortunately with these kinds of studies, we have to consider they can either be honestly flawed, but worse than that the studies can be dishonest to attract funding.
afaik the bases of e-juice were studied for ingestion, not inhalation.
edit: i was thinking of diacetyl which is sometimes used as a flavoring additive and caused a bunch of lung injury in the early days of microwave popcorn manufacturing. While looking through these I stumbled upon vitamin e acetate (used as a condensing agent in vape products) and it sounds none to good for you either. https://pmc.ncbi.nlm.nih.gov/articles/PMC6952050/
Nope, PolyEtheleneGlycol (PG) is the carrier in Ventolin inhalers. Glycerine (VG) is something the body knows how to handle because it's the chemical backbone of triglyceride, the most common form of human fat. VG and PG are the usual bases in ejuice.
Valid point for the majority of flavours though (maybe 1-5% by volume), although mint is likely fine and used in some medical contexts and for some reason tobacco flavour is prescribed in Australia, probably because it's disgusting.
Seems like they just use pH-adjusted salt water for it? Been looking for more data but I'm having trouble finding anything that isn't behind stupid paywalls.
