Hi there!
The administration method is pretty important IMHO. I burnt a lot of spice in the beginning, before I found other ways to vape. For me personally, burnt spice affects the trip, and not in a positive way. So I want the vape to be smooth, effective and be able to take 30mg in one hit.
So rhe gvg, direct e-mesh, nail rig etc are recommended for breakthrough doses. Or you could make enhanced leaf and smoke it in a bong.
Changa with added harmalas, has quite different qualities than crystal dmt when smoked.
For microdosing, e-cig with the preferred dmt to liquid ratio.
This is just my experiences. Other nexians might have other preferences than me.
Safe travels mate.
