Wouldnt know, theres a fairly easy looking extraction method http://www.erowid.org/chemicals/dmt/extraction_guide1/dmt_extraction_guide1.shtml
You're going to be hard pressed to find someone with DMT crystal in NH. I could see maybe in the Manchester area, but even then only with a dealer who takes his stuff seriously. I think your best best would to order some Hostilis bark and do an extraction yourself. Yes it's harder, but if you truly want to experience DMT then go for it. I just hope you're ready.
