A given drug sample can have multiple positive results for different drugs. One way to examine these results is to look at how often things are detected together. In the heatmaps below, we present the percentage of samples testing positive for the pair of drugs or drug categories listed. This comparison of the co-presence of two drugs cannot account for the fact that there are often three or more drugs present. 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 row marked Ketamine and the column marked Cocaine, you can see that 3 samples involved cocaine and ketamine, with or without any other drug mentioned here or any drug not included in the matrix. This is the same 3 samples in the Phenethylamines (MDMA, MDA, etc.) and Cocaine cell, as the 3 samples positive for cocaine were also positive for ketamine along with one or more phenethylamines. If you mouse over the Methamphetamine alone cell (Meth row and Meth column), you can see that one sample tested positive for methamphetamine and for no other drug category in the matrix. Moving along the Fentanyl row or column, you can see that one sample tested positive for fentanyl and one or more fentanyl analogues but not any phenethylamines. Three samples sold as MDMA or MDA had no drug category presented.
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 are cumulative and reflect all confirmatory testing results as of 3:30PM PDT 17 June 2024.
