Hmmmmmm............and here I thought it was a pretty valid question, considering that vaporizing basically targets THC and leaves the CBD/CBN's alone, which is one of the main reasons why vapping gives you more of a clear head high than a couch-lock high, that the CBD's offer. My first thought was that being that the THC content is higher in Sativa's, that it would be a better choice for vaporizing..........regardless of my personal tastes. I could be wrong though, and would welcome further discussion.Acolyte of Zinglon said:you cant really ask a question of whats "better" on a matter of personal preference such as this, tastes vary
Significant amounts of benzene began to appear at temperatures of 200 C (392 F), while the combustion started at about 230 C (446 F) or beyond. Traces of THC were detected from 140 C (284 F).lwien said:Hello Ben
My bad. What I failed to mention is that I was primarily referring to the use of the Purple Days which has a fixed heating temp but regardless, doesn't going into those higher temps with any vape start to get you into combustion?

TOTALLY agree. Wonder why that is? Kinda touching on the same issue in that other thread I started today regarding the differences between smoking and vaping.bongoman said:It's an interesting issue. If you hang out on growing and medical forums, you'll see a lot of emphais being placed on the distinction between the cerebral sativas versus the heavy indicas, but in my vaporiser the distinction is largely lost.
I vape indica dominant strains largely just cause that's what I have on hand - I vape them during the day at times when I need to be functional and they go fine. If I smoked them I'd be wanting to go have a little lie down for a while I think.
Likewise if I smoked some tropical sativa, the distinction would be very clear. But in my vape, the distinction is largely lost - I get the typical vape high regardless of strain. That is, I get a very clear, very functional high with no anxiety, no paranoia, no sleepiness etc.

This info has been copied and pasted on various forums, but nobody seems to have the source anymore. If I ever saw a source quoted, I can't remember. Here's the info in chart form. Looks like it's close to the original document, but still no source. http://forum.grasscity.com/medical-marijuana/373071-properties-cannabinoids-pic.html4:20 said:Wow, Max, what is your source? You have the boiling temperature of most of the interesting compounds ! I ve never seen such details before. Let us know the link/ source please, this info is GOLD.
The reason why the PD and the iolite vaporize a good amount of thc is because the herb is sitting in the chamber retaining heat. Even though the air itself is 375f, the herb is holding heat and if air is not going through the chamber constantly to keep it at a constant temperature the herb will be a little hotter than the air which will help release some thc. Fibers tend to absorb heat very well which will help some of the melted resin vaporize.max said:This info has been copied and pasted on various forums, but nobody seems to have the source anymore.

So I've seen 3 different, legit looking, temps (or temp range) for the release of THC- 157, 140-185, and 200. Confusing and frustrating. Is vaporization point different than boiling point for these chemicals? Water and other substances with liquid content release vapor long before they reach boiling point. From personal experience, I'm convinced that I'm getting THC from vapes like iolite and PD, where the temp is fixed below 200 C, so I'm inclined to go with the lower figures.

I think this lack of consensus for how much heat you need to get THC is a reflection of the almost underground status of cannabis research. We get twisted, even false results from pharma studies because the big drug companies are usually financing them, and there's big bucks involved. Not surprising that we can't get consensus on studies where there's no profit making involved and the interested parties are us 'illegal users'. :/
As for Sativa vs. Indica, I think the consensus is that S is more like vaporizing, and I more like smoking, but vaporizing (and the temp used) seems to be an equalizer to some degree. I'm kind of 'in the back woods' when it comes to knowing what strain/type I'm getting. It's getting better, but for most of my 'weed aquiring life' it's been more like just 'the good, the bad, and the ugly', with the occasional appearance of top quality.
Since I have no source for the temp chart, I have no way of knowing.It would be interesting to know if the boiling temerature that you have copy-pasted are the boiling temperatures under vacuum conditions or normal (Vacuum pressure).
The Classic temp variation is supposed to be plus/minus 5 degrees C (9 degrees F). The Digit's variation is advertised at 1.5 C, 2.7 F.The thermostat in the volcano (classic) gives a temperature range of 15c.
I remember when vaporizers were starting to get popular back in 2003 on OG(overgrow) bubbleman said that the heating temperatures of the vapir and I think the volcano wern't precise because of the steel screens and some parts of the herb actually get's hotter because of it.max said:I find it hard to accept a high temp release point for THC. Let's look at the Volcano. Been around for many years. A very high tech, high quality design. Many people have been happy with and recommend a temp range of 5.5-7, which is about 363 F to 396. With the 9 degree F variation in heater block temp on the Classic (with setting 6, which is 374, temp would range from 365-383), only a setting as high as 6.5 would sometimes release THC. This means that either Volcanos have been heating higher than designed for all these years, or many people have been happily vaping bags of vapor for years that contain no THC.
Aromed is another high tech, medical quality vape made in Germany. The purchase is even covered by some insurance companies over there. On this one, with its digital display, we'd also have to accept that it doesn't heat to the advertised temp or that medical patients have been happily vaping under 200 C and getting no THC.
Other high end digital whip units like S Vapezilla, Vaporfection, and Evolutions would be in the same situation. It's not very likely, IMO, that all these vapes heat considerably higher than advertised on the displays, or that all the users of these vapes, over many years, wouldn't have noticed the lack of THC effect when vaping below 392F/200C.
Since I have no source for the temp chart, I have no way of knowing.It would be interesting to know if the boiling temerature that you have copy-pasted are the boiling temperatures under vacuum conditions or normal (Vacuum pressure).
The reason why carbon monoxide is released at the high temperature around 200c is because unless you gradually increase the temperature, you will burn some essential oils that vaporize at lower temperature if you vaporize everything at once and this is what creates the carbon monoxide and tars not just heating at these temperatures.4:20 said:Absolutely true,
Max, you could buy a thermometer type K and test the temperature in your vaporizers. In the Volcano, my favorite temp is 6.5 , I don t have my datas here, but from what i remember is that it is always under 195c (383 F). The thermostat in the volcano (classic) gives a temperature range of 15c. Between the time the thermostat start and shuts off, the difference of temp is max 15c, The digital one might be more precise, but so far (i use it since a few years) , No complains. Temperature above 200c (392F) don t seems to fit the purpose of vaporizing : releases of carbon monoxide and not sure we get more effect (except maybe the extra buzz given by the CO intoxication).
Anyone have tested temperature/effects? with a precise thermometer?
