If you do this be sure to buy BPA free receipt paper

Handling receipt paper is what turned out to be the cause of the high BPA numbers when boba tea was tested https://x.com/natfriedman/status/1899641377002025252





I did! I also use gloves when handling a large amount of the receipts.

I worked as a cashier for years in my teens and twenties though, so it’s probably already in my blood.


I mean, over time it would exit right?

It lingers in fat tissue and once at a low enough level your liver doesn't really clear it. But that kind of level isn't necessarily linked to increased risks of diabetes or heart disease.

this one time when i was young and dumb and into smoking weed, i remember running out of rolling paper so i rolled a joint using a supermarket receipt i had and smoked it

this was like 20 years ago, still makes me shudder after i learned about the BPA stuff


A few years ago my friend's mother started using medical marijuana for pain management. My friend had to explain that no, you should not make a pipe out of a coke can because of the plastic liner, go to a head shop and buy a glass pipe like a normal person!

> you should not make a pipe out of a coke can because of the plastic liner

I'm fairly sure it doesn't make much of an health impact considering the hot smoke you pull into your lung, but when I was kid and we made pipes out of cans in "emergencies" we'd use the outside of the can as where you put anything with fire, you don't have to turn it inside out to be able to smoke out of it.


> we'd use the outside of the can as where you put anything with fire, you don't have to turn it inside out to be able to smoke out of it.

This is what I pictured, but now I'm curious how you'd use the inside of the can.


Some stoner-engineering could hook up two cans with each other, one is the cup you use for burning the material and the other one the "water-passageway". Obviously not recommended as there is plastic liner on the inside, but in that way you could use the inside :) Basically a bong in two pieces made out of two cans.

genius

Heating up plastic gives off all kinds of really nasty organic compounds, far worse than the drug... doesn't need to be direct flame.

Heating plant material also gives off lots of carcinogenic stuff, tar and so on

Cheeseburgers are bad for you, but you shouldn't put motor oil on your cheeseburger...

You win some, you lose some :shrug:

Fun fact, that extremely thin paper used in bibles is usually hemp paper.

Genesis 1:29, anyone?

It's Genesis 4:20, you silly

The products of combustion you inhaled are likely far worse.

I mean... the weed was going to get smoked, it was definitely the receipt that was the foreign invader here.

The fact that you did something intentionally doesn't automatically make it less of a mistake.

Yes it does

No it doesn't. Worst mistakes are usually the ones when somebody does intentionally something that seemed like a good idea at the time.

https://en.wikipedia.org/wiki/Bisphenol_A#Health_effects_and...

"In the 2010s public health agencies in the EU,[81][82][83] US,[84][85] Canada,[86] Australia[87] and Japan as well as the WHO[12] all reviewed the health risks of BPA, and found normal exposure to be below the level currently associated with risk."

If it has some health effects, they've been incredibly hard to actually pin down..


“Normal exposure” is doing some heavy lifting in that sentence. Presumably having all your daily texts arrive on such paper wouldn’t be “normal exposure,” which if I recall correctly is handling a receipt for a few seconds a day with only your fingertips.

You do know that BPA-free just means they use BPS or some other bisphenol plasticizer, right? Right? Because all of the research was focused on BPA and nobody tested BPS even though they're quite similar chemically.

You just can't polymerize plastics without a plasticizer. It's just not allowed by chemistry. No free lunch.

If you want something that's not going to leach huge amounts of plasticizers onto your fingers, use an inkjet or a laser toner printer or a laser marking machine.

They don't really make those for receipts, though, because fingers tend to be wet and powdered toner is expensive.


There are alternatives like Blue4est available, though. They don’t use bisphenol or other chemical developers.


Any recommendations on where to source BPA-free thermal paper? I've tried to source BPA free shipping labels in the US and found them unobtainable.
