Poop in Hashish

Recommended Posts


The aim of this study is to analyze the adulteration and contamination of cannabis resin obtained on the streets of Madrid, in order to establish whether it is suitable for human consumption. A total of 90 samples obtained through street vending in the Region of Madrid (CAM) were analyzed. Our results showed a direct relationship between the shape of the samples (acorn or ingot) and the presence of foreign elements, adulterants and microbiological contamination. Foreign elements were found in 64.7% of the ingot-shaped samples and in 30.2% of the acorn-shaped samples (p<0.01); 25% of the samples were deliberately adulterated, 66.7% of which had an ingot shape. With regard to microbiological contamination, 93% of acorns were contaminated by E. coli, compared to 29.4% of ingots (p<0.0001). In addition, all samples with fecal odor were acorns and were contaminated by E. coli. Ten per cent of the samples were contaminated by Aspergillus; of these, 66.7% had the shape of an acorn. Overall, our results showed that most (88.3%) of the hashish samples were not suitable for consumption. This percentage was significantly higher (p <0.0001) in acorn than in ingot samples (100% vs. 58.8%). Hence, illegal street vending of hashish constitutes a public health issue.






The only adulterants identified were glucose, sucrose and pine resin, products commonly used to improve the external appearance of hashish, giving a shiny and sticky appearance or delaying the drying of the sample. Unlike samples adulterated with glucose and sucrose that do not represent any health risk for consumers, the presence of pine resin residues in hashish is related with irritation in the tracheopharyngeal mucosa, and therefore these samples cannot be considered fit for human consumption.


All contaminated samples in our study had E. coli counts greater than those allowed (Table 3) and were therefore unfit for consumption. Moreover, the large differences observed in the E. coli counts (Table 3) likely reproduce the differences in the hygienic conditions in which hashish is produced, transported or stored. Acorn samples are commonly transported inside the digestive system, which might explain the fact that contamination by E. coli was especially significant among acorn samples compared with ingot samples (88.9% vs. 11.1%).




If that last sentence didn't grab you, this is from a Gizmodo article on the above:


Speaking to Spanish newspaper El País, one of the researchers on the study, pharmacologist José Manuel Moreno Pérez, explained the reason he believes the acorns are far more likely to have bunny muffin in them: Smugglers often swallow the acorn-shaped bags, which they call “bellotas,” then travel from Morocco to Spain. “When they get to Spain, they take a laxative and expel the bellotas,” Pérez told El País. “And then they’re put on sale.”
