the stronger the smell of burnt parsnips the more played out the material is and the worse the taste IME.

Looking forward on making some bakedtreats with avb and rosin tech leftovers.. just a plan on upcoming trip, lets see how it goes.. If done, they'll be in the travellogue.

Please take a look at the link below, it has details of a study carried out by Leiden University in the Netherlands on vaping temps for the most effective THC and CBD administration.

Science is breaking down a lot of misconceptions, there are definite advantages to nuking your herb. I prefer lower temps as I use ABV for edibles but eager to try a full heat blowout with some ice in my water cooler now (coughing fit included).

Thanks for the information.
The article addresses a problem I have, which is that I don't get high with vapor.
I had always been told that 185-195c was the sweet spot when it comes to vaping.
Now that we have scientific proof, perhaps I shall give vaping another go, at 230c.
Cheers

Anyone wanting a full on medi or knockout hit as I was advised on here try 260c in the EQ that's hot & harsh but night night

Also having tried more than a few times now from our own AVB + others donated for testing CM is bang on about keeping the temps low if you want to cook with it , the hotter the temp/darker the AVB the lower the effect

I have some donated AVB which was vaped at 200+ & am yet to test if a coconut extract will serve better than butter for edibles

Started collecting for you again FT. Love your choccies 200 is as high as I go with it. Unless I'm desperate

230? By the way what is ignition temp then?

[CloudMaster]

290c/554f is combustion point

[spidergawd]

Wow, I've got a long way to go .

Interesting read....what about the harshness increase with temp increase? Is that just more hot thc filled air causing the throat to burn? I always assumed it was plant material causing the cough at higher temps..... Hmmmm,

When using a table unit with balloon, you can try to wait a minute or two in order to allow the vapor to cool a little. That should take the hot air harshness away. Probably will cause the bag to get sticky sooner though. I sometimes saved up balloons of the Arizer EQ by using a small cork. Vapor felt really cold after an hour, but it was still there taste and effect wise.

Interesting article thanks for posting that.
I'm pretty much a full time convert to vaping - but I cannot give up my bongs or the odd pure fattie, it always draws me back. I'm a vape at low temps man myself so it's really interesting to see that break down of cannabanoid content in the vapour - looks like I'm gonna have to push harder!

My asthmatic lungs struggle with big rips on anything that's burning and even a medium size vape bong hit at really low temps will make me cough and splutter - it's a different cough to one from smoking for me, feels throaty rather than chesty so I've always assumed that it was caused by hot particles hitting the throat… I've also always assumed that the pop-corny taste (burnt parsnips I saw it described as earlier in the thread which had me with my head in a jar of ABV saying 'yeah yeah it does smell like burnt parsnips" ) was due to plant material beginning to combust or breakdown or whatever the correct term is - If I've understood it properly, that seems to be borne out by the article/study.

Slightly OT I know but:

I've never actually had a go on a volcano / bag style vape - so quick question, how long does it take for the vapour go stale and taste bad if you leave it in the bag?

Both Benzene and Naphthalene compounds (aromatic hydrocarbons) are released during the vaporisation process, both compounds have been tested and show evidence of carcinogenic activity.

Looking at the levels of these compounds, up to 230c/446f, the following has been shown in studies:
Inhaled benzene is primarily expelled unchanged through exhalation. In a human study 16.4 to 41.6% of retained benzene was eliminated through the lungs within five to seven hours after a two- to three-hour exposure to 47 to 110 ppm and only 0.07 to 0.2% of the remaining benzene was excreted unchanged in the urine. After exposure to 63 to 405 mg/m3 of benzene for 1 to 5 hours, 51 to 87% was excreted in the urine as phenol over a period of 23 to 50 hours. In another human study, 30% of absorbed dermally applied benzene, which is primarily metabolized in the liver, was excreted as phenol in the urine.

Combustion produces tar, from the burning in smoking. Tar from vaping is the essential oils from the plant after being extracted using heat but not enough to burn them.

If you look at the diagrams below, they give you a better picture of what is produced through a range of temperatures (byproducts also contain terpene compounds although it does not specify on the diagram so its not all bad stuff):





Looking at the diagrams above it appears to be healthier to vape at 185c/365f than at the lower temp of 170c/338f.

I have a question for some of you folks who use higher temps with vaping, how do you manage to inhale vapor that hot? @ FT, do you use the whip straight at 260c, if you do then you have lungs of steel!

Will edit this post later to show you my set up but I have my Arizer EQ connected to percolator glass, ice cold water in the glass and ice cubes down the stem, at 260c which is the highest you can go on the EQ, coughed my lungs up on the 2nd chamber full despite this.

Never tried vaping below 200, started at 260 when I first got my arizer, stayed there for ages but have gradually sunk to 200. Definitely makes a difference to the effects of abv, the lower temp stuff's a lot more wobbly.
Gonna try back at 230 for the day and carefully study the effects
As for inhaling vapour straight from the whip at 260, years of inhaling smoke made it possible.

Was using Bluebird's volcano last time I was over and the guy there turned it down when he saw how high I had the temp, think it was up to the top (230)
