Sounds like either impure or old spice.  i've read a couple threads about people leaving there spice in a hot car and coming back to find an oil that was reddish when it re-solidified.   dmt n-oxide is very reddish brown and although it isn't as potent...it is smooth and very visual.  Some of the gunk left behind after re-crystalizing is red-brown and not active though..so who knows what you have there.

spice is just easy enough to be attempted by anybody. The end result can vary based on the time and patience that the extractor puts into it.  Noone will be care more about what goes into your body than you.  now that you know you like dmt...extract it yourself (if its legal to do so where you live) and be sure of what your vaporizing.
