I've been wanting to share my thebaine PST horror story on this subject. I first got some high thebaine pods some years ago. Then, the symptoms consisted of moderate to extreme nervousness and additional shortness of breath. I had an unexplained grand mal seizure the same week I was going through this batch of poppies though it was far enough from a dose that it was undetectable in my blood. I was never really sure about the cause of this seizure until the following happened.
In 2015 and '16 I was using a very commonly used / reviewed brand of seeds. They were very strong, and were great for just a morphine effect at first. After a few months I had a habit of course.
It only took about one or two grams of them to achieve a nod. It started with panic attacks, accompanied by a pounding heart/ shortness of breath. I chalked it up to just regular respirtory depression, but this was different - There was a panic / confusion factor. If you get dosed with thebaine you'll know it. It's as dysphoric as the literature says it is.
The second thing that started to happen was when I would take a nap or try to sleep at all.. as *soon* as I started to drift into REM sleep, I would have a violent seizure like jerk. It was scary as hell. I had to dose this stuff, as I only had a 5lbs bag of seeds and no kratom or anything to fall back on and every time I tried to sleep, these convulsions would literally make me jump up off the bed.
I'm confident had I continued to take the particular batch of seeds I would have suffered further. I currently am doing well on kratom, but miss seeds. I play around with the idea of getting a pound every once in a while but I have trouble enough moving my bowels on daily kratom. With PST I have a daily impaction. I used to drink epsom salts daily just to go normal.
Careful with thebaine
