That’s sketch but I’m skeptical that what’s being sold as thco is even thco. That paper says 2-3 times as potent. I tried some that I believe originated from cannaclear and I noticed almost zero effects …

Saw on ig. Das no good

Also: this is looking like all acetate cannabinoids. BTW

Not just thcs

Read through it and yea this doesn’t look too good.

Who knows what’s in store for the people consistently vaping or dabbing THC acetates over the next few decades.

Is there a certain level of toxicity in inhalation for Ketene (Not all that familiar) this study pretty much concludes that they do not know?

5ppm is what is said in the study

I wish i could say this is suprising but real chemists have tried doing conversions/making synthetic cannabinoids for years and it often resulted in death. Don’t see why thats gonna change with the garage chemists.

Must have missed that, thank you.

Well that ain’t good. They should be running other adulterant tests to make sure there’s no mineral oil or crap like that. Is there an accompanying study?

The stuff I posted a pic of in the second post has a definite mineral oil consistency. Complete opposite of the polymer consistency of delta8.

And it was not 2-3x potent as thc as it’s been clinically studied to be so probably totally bunk. Cannaclear is supplied by ? Lol

The font on the packaging is pretty telling

Isn’t this just talking about Vitamin-E acetate? Seems like a study from 19-20?

No, it shows cbdo, d8thco and d9thco all made ketene gas

Similarly to vitamin e acetate.

It’s in the title.

Did you happen to read how much gas was created? I just finished reading the whole thing and while it’s fairly alarming, I don’t believe the sky is falling. They even stated in the article that Ketene reacts with water to form acetic acid, and the effective dose on the lungs in humans would be expected to be less than their iron lung apparatus. They also stated that they expect most retail products to not contain pure acetyl noids due to incomplete reactions, which would mean less ketene production. Their d8 sample was half of the NIOSH threshold at 0.022mg.

(High thoughts) Thinking about this topic now, and particularly where vaping is concerned, according to the study when ketene contacts water it forms acetic acid.

So, perhaps any kind of bubbler in your vapor path would seemingly eliminate the concern?

“This is true with any acetate if subjected to high heat. However in my opinion the amount of ketone formed appear to be too small. Need to check the toxic dose. If the vaping temperature is 250 or less then that reaction wouldn’t happen” -Dr. El Sohly.

Fear mongering at its finest. If you want to take a dab at 370-560C, then you probably have bigger issues coming to you than ketene formation haha.

I didn’t read this article as fear mongering. The article seemed fairly grounded and they even stated more studies were needed. I just think people need to keep a level head and think about this problem using science instead of emotion. I wonder how many people will jump to a conclusion about the ketene production of acetyl noids while scrolling on their phone huffing a cigarette?

So everyone dabbing above 250c is fucked…

Kind of hard to call that fear mongering when the most common smoking devices second to lowest temp settings are above that.

Puffcos temps settings are as follows: 450/500/550/600°F, or 232/260/288/315°C

No read the study. There is not enough ketene formed at their temperatures for toxic levels and also not enough data to support any claim.

That is just a direct quote from the #1 cannabis chemist in the world.
