> The BMJ Oncology study concludes that “dietary risk factors, alcohol consumption, and tobacco use were the main risk factors for major early-onset cancers.” But it adds that “prospective lifetime cohort studies are needed to explore the etiologies [causes] of early-onset cancers.”

Whatever we're consuming is most likely the culprit (or whatever is being sprayed on/injected into/fed to what we're consuming).

All the studies say glyphosate is safe. But, glyphosate use really ramped up in the 90s with "round up ready" GMOs being created in 1996. It is even sprayed pre-harvest to uniformly dry grains for harvest.

Who knows if glyphosate is causing cancer. I think there is strong evidence that it is the cause of the rise of celiac disease cases.

i am not convinced the rise of celiac is not due to some combination of better testing/new thresholds and more awareness to get testing

Gluten compositon might have changed:

if you actually read the article it's basically a negative result

I actually did and it said: "While the proportion of critically viewed gliadins fell by around 18 percent, the proportion of glutenins rose by around 25 percent."

Sure, you can say one thing is a little bit lower and another thing is a little bit higher, so it is the same. But as I always said: Units! Units! Units!

Maybe the glutenins are underrated?

and also that any drift over time is swamped by weather effects

What's your background?

Actual lol. Thank you :)

Isn't tobacco and alcohol at a high time low in the younger generations?

AIUI gen z is slightly more health focused and has lower alcohol usage. Millennials and gen x make up for it.

Not to mention that they’ve cut out alcohol but added vapes and what seems to be a healthy amount of marijuana. I don’t think that makes them healthier overall.

cutting out smoking and alcohol and subbing in vapes and marijuana is almost certainly a net win healthwise

Unless it isn’t. Frankly we don’t know what the long term effects of vaping and marijuana usage are because we’ve not really dug into them.

there are a fair number of long term studies in marijuana.

it’s clear that for normal usage patterns compared to normal tobacco usage patterns, the cancer risk is much lower.

How about compared to alcohol? Various kinds of alcohol? The claim was that vaping and marijuana were both lower risk than smoking and alcohol. I think jury is still out.

Marijuana consumption is well-studied to be less bad than alcohol. Vaping we have strong reasons to think is less bad, but it is not well studied.

What is a healthy amount of marijuana?

This leads to obesity and terrible diets as a rise.. If this study is worth anything.

> tobacco use

What's the worst part of a cigarette, the fact that it has tobacco, or the fact that it has like 100 different cancer causing toxins?

My dad is 98. Started smoking when he was 9. At one point he was smoking 70 a day. He worked as a fireman on steam trains when he was in his 20s. He lived in London during the 1950s when the smog was so bad you could walk into a lamp post when the lamp above was lit. People warned their houses with coal, powered the city with coal, burnt their trash in the back garden and smoked a lot. Sure, the average lifespan was low. But he only quit smoking in the 1980s. I'm not saying that smoking isn't bad, but if there is a sudden rise in cancer among young people, it's not that simple. The number of smokers today is tiny. In the UK, smoking rates among young adults (aged 18-24) have significantly declined over the last few decades. In 2011, about 25.7% of this age group smoked, but by 2021, that number had fallen to 13.2%. I don't have stats from the 50s but according to my father he didn't know anyone who didn't smoke.

Self-explanatory:

Vapes are at all time high though.

I'm still trying to find the memo I missed that made it socially acceptable for folks to vape indoors. Come into my house and vape around my kids? Really?

Who is walking in to your house and letting off clouds? Generally you ask, or if your host is a vaper wait to see if they do first.

For all other public indoor settings its already illegal.

I've had to tell off at least 2 people who were vaping in the climbing gym in London.

people think it is more surreptitious than it is

Sugar

I see people say this but what's the mechanism?
