Sleve
Dear Sleve: Are you buying your hash from the same dispensary, dealer or extractor? This sounds like a production issue during the growing or extraction process. And if I had to put my money on it, I'd bet it was something used in the cultivation stage that was compounded during extraction. This is a common cause of contaminants and impurities in hash, from pesticides to nutrients.

A burnt popcorn flavor in hash usually involves sulfur, a common cannabis-growing nutrient.
