Headrush from vaping on re-cook

Greetings;

I use a Grenco G-Elite to steam ( I hate the term 'vape') 'dried leaf' pot.

If you are unfamiliar with the Elite, it fires up to your preset temp, and stays there for 5 minutes, then initiates an 'auto off'.

I have been through several units damaged, apparently, by overheating. The polybutylene terephthalate of the mouthpiece is rated at a max temp LOWER than the Elite can achieve. Ergo, above 375 is basically a 'self destruct' mode. At 375, I barely taste anything after the first hit. I see no vapor when I exhale, and I feel nothing in my throat as far as heat, moisture, or any other type of irritant. Were it not for the gradual, subtle change in discomfort, I would think I was breathing air. I do a long, slow, 5-count intake, hold for a 5-count, and then a three count exhale. Similar to my 'relaxation' breathing exercise.

So...
I load up my Elite (about .15 to .25 grams) and, if not preoccupied, can get a good 8 draws before the lights go out. I let the unit rest for about 10 - 15 minutes to cool to ambient temperature, before firing it up again. A few times now, after about four or five draws, I will take a draught and get a head rush.

I find it hard to imagine that I am getting the 'best of my bud' after so much cooking. I am wondering if the deep inhalation, and holding of 375 degree AIR is causing the rush.

I just purchased a new Sativa from the dispensary. I proceeded with my usual amounts and process. After a few hits on my 'second burning', I took a toke and held it while standing and walking, and bent down for something from a lower kitchen cabinet. When I stood up and released, I got a head rush - PLUS. I came to on the floor. I went into a GIANT full body sweat. I was only out a moment or so, but was surprised I'd gone down. My last recollection was leaning forward onto the counter for support. Though I was able to get up right away, it took a few hours to get reoriented.

It wasn't until the next day I realized I'd not bombed my head on the floor but rather fractured a cabinet door. Something that may have saved me greater damage.

I had chest X-rays a few months ago, and my lugs are clear as fresh spring water. I saw a cardiologist some time ago who said I MAY look to have an angiogram done before too long. Nothing 'serious', more a preventative thing.

So, I wondered if one must be cautious about getting the last of their load when there isn't much to steam, and all one gets is hot air?

Thanx in advance.

Vapefully;
Thanks for your input. I could not find the referenced pic of damage. I did not have issue with the removable mouthpiece itself, but rather what it clips on to.

See pic.

I did research on the plastics. I was surprised that the unit was made to exceed 'safe' temperatures.

I seem to be having 'head rush' issues at other times. I seem to only head rush from vaping at the last of my load. I have an appointment with a cardiologist about scheduling an angiogram. Something one suggested five years ago. (Recent x-rays show clear chest and lungs, and an EKG a week ago indicated 'I got rhythm' and and a good, strong beat one can dance to.

I have been compromised with 'fatigue' for some time, and am 'getting tired' of it.

I 'taste' no plastic. I have been experimenting, and can near give myself a head rush just inhaling through the Elite with it being neither loaded nor turned on. The long, slow, semi-restricted intake, and held breath can do it to me at times. Especially if repeated.

I also wondered whether the 'steam' was OK but if just plain 375 degree air was having an effect. So I fired it up empty, and took a few drags, but didn't seem to notice anything. Here in AZ, our 'dry heat' may have me a little more conditioned than some folks. But with it empty, and at operating temp, when I drew, I felt/tasted ZERO! Like 'is this thing ON'?

I also wondered if perhaps I am trying to get too much out of my load. I wish there was SOME way of knowing the pack is played. Multiple cooks at the same temperature leave the leaf a light tan-brown, whereas when I steamed at 400, it was quite a bit darker.

Thanks again for your input.
