The hard strong residue substance formed in marijuana grinders/tins, especially located on the teeth of
the grinder. Resembles a dough like concrete, fairly hard, dry and brittle, but more malleable than concrete.
Maintenance of a marijuana grinder typically includes the scraping of weedcrete from
the grinder with a metallic object such as a blade or scissors. Weedcrete is kept/consumed rather than wasted due to it's high THC level.
A combination of extremely compressed high THC plant matter, moisture and further THC matter (Kief). High THC potency, but tedious to harvest.
Weedcrete is considered one of the world's strongest substances.
