Well, lets put this here too:
The boiling point of DMT freebase seems to be around 160C and with a vaporizer you might want to set the temperature around 180C for a solid and constant vaporization.
I myself am testing with the
Plenty vaporizer and using the
liquid pad that you get with it, I can vape around 5-10mg of DMT in one pull, depending on your lung capacity and how deep you want to inhale. So to vape 25mg of DMT freebase with the Plenty you need around 3 deep pulls.
As for the vapor being harsh, I guess that depends on how the vaporizer can cool the vape on the way to your lungs. The Plenty does a good job at cooling down the vapor with it's weird twisted whip.
Kind regards,
