Aloha all, I'm new to this forum, and pretty new to DMT as well. I've just finnished my 2nd sucsessfull extract of MHRB and have been reading a lot of threads around here for tips and ideas, thanks for all of your help!! Even though you didn't know you where helping.lol I guess my reason for posting is that I seem to have an extreemly high tolerance for DMT. My friends smoke the same ammount or less than I do and all of them have heard the [b:1722f81be8]loud[/b:1722f81be8] rising tone and seen the mandala form in their minds eye. One of my buddies has had a very profound breakthrough with telepathic contact with a "super inteligent" mantis-like alien, as he puts it. He experienced this without having heard of mantis-like DMT entities ever before. I on the other hand, I can't seem to get much more than a heavy "mushroom or acid-like" effect. No loud rising tones, no mandalas or crasanthimum type hallucinations. I do get lots of geometric patterns and size distortions but I have never lost awareness of the room I'm in much less been close to a breakthrough. Anyone know of a reason why a person may not be very sensitive to DMT? I've done a lot of research on the subject in general, I have been looking for DMT since I read about it when I was 19 waaaaay back in 1993 and have never heard of someone not being very susceptable to its effects. Other than MAOI's (not looking to spend 8 to 10 hours out there) is there anything that enhances the effects of smoked DMT? Thanks for your input!! Cheers!! WS
