Hi, I am a new member to this site. I have been on here before though when I learned what DMT was in my early teen years, never thinking I could possibly extract it myself. I just got back from smoking some very good spice. I think that was my 5th time.
Im not sure exactly why I am telling you this following story/lesson I learned about DMT:
Two friends and I were parked on a gravel road in the middle of nowhere by a large quarry ridge, we thought it would be scenic. My two friends vaped some spice over a tiny amount of weed. These crystals were acquired using Noman's STB and were all white. I took the third hit and torched the weed and taking a medium sized hit. After a good ten seconds I felt the effects but I also felt the urge to go to the washroom. The feeling kept multiplying until well...... I pissed my pants. There was absolutely nothing I could have done to prevent this after having that hit. It just goes to show the power of this chemical.
It was a great experience though. I tried to get out of the truck but couldn't see the dashboard. It was hidden behind a psychedelic blur. This was my most powerful DMT experience to date.
So the morale of the story: Always go to the washroom before smoking spice.
What a beginner mistake I made..... 
Anyways, I just thought this was a good story to get the attention of a few people. I find this site very useful and would like to get to know a few experienced people.
Peace
