What's in the last 100 samples sold as benzodiazepines?

How often are drug types found together in confirmed drug checking results?

A given drug sample can have multiple positive results. On way to examine these results is to look at how often things occur together. In the heatmaps below, we present the percentage of samples testing positive for the pair of drugs or drug categories listed, in the most recent 100 samples sold as benzodiazepines (which means the percentage is the number of samples with that pair). The diagonal (where the column name and row name are the same) represents those samples testing positive for only that drug category (these samples may have tested positive for a drug category not listed here). The rows and columns are ordered from largest to smallest share of drug checking samples, alone or in combination. For more details on drug categories named, click here.

For example, if you mouse over the Non-Rx benzos alone cell (Non-Rx benzos row and Non-Rx benzos column), you can see that 73% of recent samples were positive for illicit benzodiazepines and no other category here. The Rx benzos alone cell indicates 14% were positive for legally available benzodiazepines and no other represented drug category. Moving along the Cocaine row or column indicates that 7 of the illicit benzo samples had cocaine. The Other analgesics alone cell indicates 2 samples sold as benzodiazepines had no benzodiazepines but did have an analgesic. Four additional samples sold as a benzodiazepine tested positive for neither a benzodiazepine nor any other drug category presented here.

Data notes

Drug testing sites can do little about potential cross-contamination: The container a client used may or may not have been used before. Therefore, any unusual combination may be due to cross-contamination and not represent drugs actually sold together. Results represent a snapshot of the last 100 samples with confirmatory testing results as of 10:45AM PST 18 February 2025.
