Background

Law enforcement agencies currently lack a reliable, portable, non-invasive method to detect recent drug consumption in the field, comparable to a breathalyzer used for alcohol detection. Existing methods — urine or blood testing — are invasive, time-consuming, and unsuitable for rapid field screening. Breath, saliva, and sweat are known to contain biomarkers correlating with recent drug use, but no indigenous, field-ready device presently exists to read them reliably.

Description

Participants are to design and build a prototype handheld device capable of detecting the presence of common narcotic substances (such as opioids, cannabis, and synthetic drugs) through breath-sample analysis, using electrochemical or equivalent sensing technology.

The device should

Provide a rapid, near real-time result at the point of testing.

Be portable and operable by field personnel with minimal training.

Indicate a clear positive / negative / inconclusive result.

Be built using accessible sensor components suitable for a working prototype demonstration.

Expected Deliverables

A working hardware prototype capable of demonstrating breath-sample analysis and producing a result, along with a brief technical explanation of the sensing method used and its accuracy on a provided or self-generated test set.

Note to Participants

This is a proof-of-concept prototype intended to demonstrate technical feasibility. It is not expected to be a forensically validated or field-certified device at the end of the hackathon.

That puts it 139th of the 240 statements that have any ideas at all, out of 240 on the board. It is moving, so the field here is already forming.

Added mid-season. This statement first appeared on 6 September, after the original list went out. Teams who shortlisted early have most likely never seen it.

Counted from the official portal twice a day. The portal itself only shows today.

What a jury will ask about this

  1. 01“Who actually faces this problem today?”

    What works: Naming one real person and what they do instead right now. Reading the statement back is not an answer, they already read it.

  2. 02“This already exists. Why yours?”

    What works: That existing tools are consumer products. Yours is built for the ministry, works offline, in the local language, on official data.

  3. 03“Then why has nobody solved it yet?”

    What works: The real blocker. No connectivity, no incentive, nobody owns the data. You only know this if you read the ministry's own reports.
