DMT occurs naturally in a variety of plants in high-enough concentrations for economical extraction. Traditionally you would do an acid/base organic extraction. But for most purposes, you can STB (straight to base) with a bit of lye (i.e. canning supply) and an organic solvent like naphtha. Obtaining powered plant material is easy, usually available on eBay or else independent sites.
