Well... The only thing I can tell you is that smoking DMT from a glass pipe is very difficult and it tends to burn the product. And. Burned DMT tastes and feels horrible.
The only thing I'll recommend to you is to make a Mini-machine. It takes about 5 minutes to make it and about a couple dollars and it's very effective. Now if you find out that you love spice like I do and have the money invest on a vaporgenie.
Also measure your dose with a milligram scale. With the mini-machine I use 40-45mg to breakthru.
And finally double check your extraction procedure.
Lastly... You didn't have have a head stroke. Don't worry about it.
Peace, and happy travels.
