Caveat emptor
This month's Paletteful Pack was a set of alcohol-based inks, and I know at least one other person in my DW circle got these, so as a warning, I found out when I tried them that they are way more toxic than even the (vague) warnings on the bottle about keeping them out of reach of children suggest.
They have a very strong smell, but my work area is fairly open (it's the loft part of a house with a large open upstairs) so I didn't even really think about needing extra ventilation. Last night I opened them up and played with them for about 15-20 minutes while watching TV, until I started to feel suuuuuper weird. It was clearly a neurotoxic chemical reaction: sweating, shaking, dizzy, headachy, and it started to clear up within minutes of getting out of the area. I've never reacted to a solvent like that before, though I've also never used that kind of ink before, but I have no problem with strong-smelling, solvent-based markers and the like.
So basically, if you use these, VENTILATE, and take frequent breaks. I played with them some more today on the deck, and that was all right; I just tried not to take deep breaths with my face close to them, and stepped away for a break every few minutes. And I feel fine. I mean, a little bit of toxic risk goes along with most art supplies. But I think I'm going to toss the remainder (I used up all the paper that came with them anyway) because they're not really enough fun to make up for all the extra precautions I felt it necessary to take. It's possible that I'm unusually sensitive to it, but it might not be a bad idea to make sure to ventilate thoroughly (outside is best, if you have an outside where you can do art) or wear a respirator mask if you're going to be using them in a small space indoors for more than a few minutes. Finding somewhere away from living areas to let them dry is also a good idea, because I also noticed that they outgas very badly; I'm drying them on the deck for the initial part of it and then moving them to the garage. Basically treat them like some sort of shop project and it'll be fine. But they aren't really suitable for doing art indoors in a combined art/living workspace! At least that was my experience.

I especially don't want my cat getting into this stuff!!!

I'm just being careful now, and I think once the art is completely dry it's probably fine, but if it hit me that hard and fast, I think they need WAY more warnings on the bottles -- I think it doesn't even say anything about ventilation, it just says that it's toxic and children shouldn't use it. NO SHIT!! I mean, volatile solvents in art markers are a thing, and I've gotten mild headaches from using them, as well as (as you said) toxic materials in paint pigments that can be bad for you over time, but I've never experienced anything like this before.

Also, Iused them again today and feel a bit nauseated, ugh. Yeah, definitely pitching these. If I want glorious colors, I’ll stick to my watercolors, which don’t make me sick!!

Let me plug my favourite book about colour history, for being really readable and giving lots of places to jump off, but Victoria Finlay's "Color: A natural history of the palette"
I don't know about watercolour pigments off the top of my head, but arsenic green was a big thing for the Victorians (and was basically all over wallpaper for a while), a bunch of the older whites have lead, etc. etc.

As far as I know, though, with paint pigments it's cumulative exposure that's an issue, rather than acute poisoning. I guess painting your whole body cadmium yellow would be a bad idea, but in general I don't worry about getting watercolor or acrylic on my hands as long as I give them a good scrubbing afterwards.

When I started buying watercolours I definitely wasn't anticipating having to make decisions like "How do I feel about cadmium? What about cobalt?"

But yeah, I'm pretty sure paint pigments (those that haven't been discontinued, anyway, like the arsenic compounds) aren't toxic to an extent that getting a little on your hands every now and then will hurt you; you just wouldn't want to moisturize with the stuff. If you were making your own paints, and getting a lot of it on your hands/inhaling the dust, it might be a problem, but probably not otherwise.

And thank you again for the warning. I am too used to nontoxic Crayola products, I guess!

And yeah - I mean, I'm also completely shocked by this because I've been using all kinds of art supplies for years and I've never had anything like this happen before! And that includes things like xylene markers with dire warnings about ventilation on the package. The worst that's EVER happened is mild headaches if I didn't get up and walk around to get some fresh air occasionally. There's no way this level of mild exposure should be causing symptoms like this for either of us.

Yikes.

It definitely sounds like they should have at the very least warned to use only in a well ventilated area, yikes. I'm glad you realised relatively quickly!
