Do most of you "vape" at a temperature that combusts?

According to many sources such as the one below, cannabis can combust at as low as 392 degrees F. So take my vape for example, FM V5.0s, which exceeds this in two thirds of its heat settings (400F and 415F)--and I don't think I've EVER heard of an FM user that primarily uses the blue setting.

This might be common knowledge but kinda seems like a bummer to me. Like is the title of this community contrary to what most of its members are regularly doing?

My Mighty goes up to 210C but I think the 210 in the Solo tastes more combusted. Even though I still take up ABV with 220C in the Bolzano (cano, we used to call it Pizza Bolzano for encrypted msgs) but it does not taste combusted. I think the convection makes the difference.

Regarding the link, I found that I get psychoactive stuff at 148C mininimum in the Mighty.

No.

I may play the heat soak game with my Solo on setting 6 or 7 when using my WTA, but the second that light is lit I take it back to 5 before I start the actual session.

The most I take my Ascent to is 392F-396F. The debate still rages on as to whether nasties start @ 401F and for me, I don't want to take the risk, plus I like to bake with my ABV so actively leave some goodness in it for edibles.

No combustion occurring at those temps.

I kind of look at heater setting as a starting point, from there its up to me to manage the actual operating temperature by addressing other variables (draw rate, grind. pack, etc) which the vape can't do on its own. So while the dial may say I am on fire I don't worry till I see a cherry.

"Combustion: Dry weed can begin to combust at around 200 °C. The maximum heat weed can take before starting to burn is around 230 °C., depending on how humid it is."

I think OP is thinking of smoke + vapour hybrid due to pyrolysis?

YES. Of course I don't think the 400F and 415F settings on the V5.0s are emitting pure smoke--the important thing is that they are potentially emitting some.

Either the information in the link is incorrect, or a lot of you are in denial about this.

My ABV can get very dark with the Haze on 2 or 4. I use higher temps with water. Maybe I don't understand combustion but I've only had the ABV so charred that only a bit of ash was left a couple of times and I don't use whatever vape that was anymore.

Nonsense. Combustion cannot occur at temps under 450f. Most vaporizers are designed not to get that hot.

Agreed. The OPs article seemed to be culling info from multiple sources that aren't mentioned, so not sure I'd rely on it.

What I've read is that around 200C, benzene starts to form in cannabis vapor, which is a good reason to stay below that temp because no carcinogens have been detected at temps below that. The same source says that combustion starts around 230C (446F).

EDIT: Here's a link to the original paper I was referencing. Its 15 years old but I think its still relied upon because nobody in the research community has ever contradicted it. If anyone has any original material that's newer please share.

you make a good point. Even if you don't reach actual combustion temps, there are good reasons not to expose yourself to possible carcinogens at high temps.

@tie if you are concerned, just vaporize the lower settings. Most of us can decide what's best for ourselves. I don't think most are in denial. We know whether we've combusted or not. Most of us have decided we don't want combustion in our lives. Fuckcombustion!!

We are all (for the most part except for @Enchantre) former combusters. Enchantre never combusted - she went right to vaporizing.:lol:

I agree its an assessment we all make for ourselves and seeing we all have different lives is logical that we have a different tolerance for risk.

My mistake. I was assuming that emission of benzene/other carcinogens was still considered "combustion." I guess a more appropriate title for this thread would've been, "Do most of you vape at unhealthy temperatures?"

Correct me if I'm wrong, but this is how I understand it:
Vaping in the range 200C to 320C (392F to 446F) is less harmful than combusting/smoking, but still more harmful than vaping below the "totally harmless zone," temps under 200C/392F.

Any vaping temperature lower than "a hair below combustion" is harmful/unhealthy for me.

Combustion temperature hinges upon multiple factors. The target heat at which any given herb may combust is relative to it's unique moisture level, altitude, atmospheric pressure, density, how it is prepared (ground fine or left in chunky nugglet form), how it was cured, heating method (conduction, induction, convection, radiation, direct combustion, etc.), local environment, and many more. I have definitely vaped tons of herb batches above and beyond 392 with zero combustion. @tie (dope name btw) this community absolutely f**ks combustion at all costs and without question :)

I only vape (dab) at around 570f on the dial of my dnail, which would be combustion city if it weren't for the helpful fact that nothing that I vape has anything that's gonna catch fire in it. :D

As others say here, it is all about the temperature and specific content of the cannabis in the chamber, not the temperature as arbitrarily read by a given vape design. This relates to the amount of resin on your buds, the way the resin is distributed (a once rosin squished bud will have a coating of oil around the outside which will need to largely boil before oxidation and pyrolysis can take place in the material it is covering), the moisture/lack thereof in the nug etc.

Remember as well that as I allude above, vapes do not all measure temp from the same place or necessarily even at all.

The dial reading a given temp does not mean that the material is exactly (or even nearly) that temperature. There is little/no consistency between different and sometimes even the same models of device in temperature measurements/readings.

You need a heat safe k type thermocouple or something functionally similar in the bowl with the material to get a relevant and comparable measure of temp from different vapes and even different units of the same model. To get this wired up safely and properly would be quite a task and would in many vapes necessitate substantial remodelling of most vapes and thus make our testing problematic and not representative of real world lol
