Head stash refers to a personal, private supply of top-tier premium cannabis bud that you reserve exclusively for yourself rather than sharing communally. Originally, the term arose as slang for a cannabis dealer’s higher-grade private reserves they did not sell wholesale. However, head stash more commonly referenced a frequent consumer’s own special supply of coveted bud squirreled away for solo wake and bake sessions or special events rather than smoking with friends. In both contexts, head stash occupied a higher echelon above one’s common stash reserved for more mundane daily puffing. Only the most discerning cannabis aficionados set aside and safeguarded a head stash of ontology-shattering bud sure to launch them into inspiration and insights each toke. Nowadays headstash has become an industry insider buzzword referencing any exclusive top-shelf cannabis brand or specific product line crafted for experienced clientele who still enjoy reveling in Arizona sunshine just like the good ol’ days.
