Substances Detected in Street Drugs

This Live Report identifies substances identified in street drug samples analyzed by GCMS (untargeted search) at the UNC Street Drug Analysis Lab. All data and graphs herein can be reused. Attribution appreciated, but not required.

List of Substances Detected

You can sort or filter the table below by clicking column headers or using the column filters. This table can be downloaded using the arrow in the bottom right corner.

Table Notes: Substances are reported in any (primary or trace) and primary-only abundance. Column called total is the number of samples that contained the substance in either primary or trace abundance (as determined by <5% peak height on GCMS chromatogram). Column named primary is the count of samples where the substance was found in primary abundance only. Primary/trace designation is based on relative peak height on the chromatogram.

Location of Substances Detected

Use the dropdown to choose a substance. The chart shows quarterly rates per 1,000 samples analyzed by US Census region.

Time Trends of Substance Detection

Select up to 5 substances to compare national detection time trends. Points show quarterly rates per 1,000 samples; lines show 3-quarter rolling averages. Rare detections won't display full lines.

Sample Volume Over Time

Programs send us samples voluntarily. Some months we get more samples than others, and some programs consistently send more samples than others. For the sake of transparency, this graph provides a rough sense of our quarterly sample volume. The most recent quarter may not represent 3 full months. See Coverage Summary to see which states samples have originated from.
