Nonprofit harm reduction, free to the public.
My name is Robert Stewart. I’ve worked in harm reduction for eight years, three of them professionally, and I bring it to community events across Washington. I perform reagent testing with a full colorimetric panel, and I use fentanyl test strips to stop overdoses before they happen. Naloxone and harm reduction supplies alongside all of it.
- Reagents
- Full colorimetric panel, including Marquis, Mecke, Mandelin, Simon’s, Scott’s, Zimmermann, Ehrlich and Hofmann
- Strips
- Fentanyl and xylazine
- Naloxone & supplies
- Narcan and harm reduction supplies, handed out at every contact
- Cost
- Free to the public. Paid for out of pocket.
Supplies
I have searched far and wide to collect the most thorough supplies I can, in order to provide extensive, discreet, proper care. Some companies carry reagents that others do not, and supply runs short, so I do not buy from only one.
Testing beyond fentanyl strips
Hofmann & Ehrlich
The indole and ergoline range.
Scott’s test
Cocaine, cathinones and anesthetic cuts.
Xylazine
Immunoassay strips.
How I process a sample
What I offer is a force against fentanyl and harmful cutting agents. Past that, stay cautious and take care of your body.
From there, what someone was told it was, and whether anyone has already taken it. That sets the order.
Then a broad reagent panel — a separate portion of the sample for each reagent, read at the intervals it specifies. Class-specific chemistry for whatever the panel leaves open. Strips at the manufacturer’s dilution, not a generic one.
Then the result, in plain language, with naloxone and harm reduction supplies.
What this can and can’t do
It doesn’t measure purity or dose. It can’t rule out every adulterant. It isn’t lab confirmation, and a negative is never an all-clear. Using several reagents and manufacturers narrows the uncertainty. It does not remove it.
Get in touch
If you run an event and want harm reduction on site, email me. Same for manufacturers, peer organizations, and anyone who needs support.
Dates aren’t posted yet. Email me to find out where I’ll be next, or to ask me to come to something. A schedule of upcoming events is coming to this page.
