I totally agree with gibran2 here. I've tried them both.
I started with a typical "meth" pipe.
l I put 35 mg's of cleaned up white crystals in a typical meth "lolly", licking the flame back and forth I melted the crystals, while while working the bulb part side to side to evenly distribute it over the lower surface. I then held the flame of a torch lighter set to low +- about 5 cm away and heated the crystals slowly until vapour began to form. Moving the flame back and forth I could work up a decent amount of vapour and the first deep inhalation left me humming with energy and seeing fractals.I was completely blown way, but this was my first time ever smoking more than 10 mg's.
I found no matter what I did it didn't really ever work up an optimal amount of vapour. The taste was very acrid and almost like burning plastic.
The residue on the outskirts of the "DMT pool" that had formed was turning brown and made it taste burnt. Once this happened no matter what I did it still tasted horrible. I had to clean the pipe with acetone to get rid of the smell.
Fed up I went out the next day and bought a glass drill and a few small 50 ml liquor bottles.
My machine completed, I loaded up 35 mg's of the same spice. The same torch lighter set to low was used while the same action as before was performed, never focusing the heat on the DMT for too long.The bottle immediately filled with smoke and I inhaled until I couldn't any more.
By the time I exhaled it looked like the machine in my hands was a good metre away from me and looked like an ultra reflective mirror ball. Soon everything turned "geometric". My entire being was hit by a wave of what I'd call "Love Energies", before the most astoundingly magnificent 8 to 10 minutes of my life occurred.
I knew this was what all the hype was about.
The taste was actually kind of pleasant and not harsh at all.
I believe I cleared most of the 35 mg's in one hit and the amount of vapour produced was high.
I've honestly never even thought of using the "meth pip" method again and have thrown the thing away.
I've actually gone a little OCD and prepared 8 more bottles for use in the future.
Hope this helps.
Peace
