DMT is Schedule I but if there is a bust in your place, they will probably drop that Schedule X charge on your lap.  There was a recent bust in the Bay Area that generated a lot of media and Nexus interest - yet all the cops found DMT wise was a quart and a half of aqueus basified MHRB solution in mason jars and some solvent, no actual final product was seized.  Though other drugs and guns were, .

Yeah, drugs and guns don't mix well and those of use who do it risk things like 10 extra years if ever nailed to the wall.

But, here's the thing.  Just be safe, do small extractions, be discrete, don't set up a soapbox to announce how wonderful DMT and breakthroughs are, don't have a lot of foot traffic at your place and learn how to vape correctly and/or invest in a vaporgenie pipe.  One thing that caused the neighbors to become suspicious in the above-referenced bust was a frequent smell of burning plastic . . .

Discretion can take one all the way from birth to death without involvement of authorities in my opinion.
