Best Method - Test everything you intend to consume
Testing everything requires dissolving your entire dose or batch in water. For drugs consumed orally, you can dissolve your dose and drink the water after testing (the strips do not contaminate the water). For drugs like cocaine or meth that people like to snort, you can get the powder back by evaporating the water (see "Getting your powder back" below).
Backup Method - Testing a portion of your drugs
If you can't test the entire dose of what you intend to consume, at least test a good cross section. 50mg is the recommended minimum. Before collecting a sample of your drugs to test, crush any crystals, shards, or rocks into a fine powder, then mix the powder up as thoroughly as possible by stirring or shaking the baggie. This helps distribute any fentanyl that might be clumped up inside, increasing the likelihood that some will be in your sample.
STEP 1: Preparing & Diluting Your Drugs
Whether you are testing everything you intend to consume, or a smaller portion of your drugs, you need to dilute the powder in the correct amount of water (the printed instructions included with the fentanyl test strip will include further information for testing pharmaceutical pills, blotter LSD, and for IV drug users).
- Weigh your drugs - 50mg is the recommended minimum. If you don't have a milligram scale, you can use a 10mg micro scoop.
- Place your measured drugs in a small container. If you are testing 50mg or less, a standard bottle cap works well. If you are testing more than 50mg, use a cup or bowl.
- Add the right amount of water. This step is very important! For all drugs, add 5mls of water to every 50mg of powder.
- Stir the mixture until completely dissolved.
- Hold the yellow end of the test strip and insert the other end into the liquid.
- Allow the liquid to travel up the strip into the test area for a full 15 seconds.
- Remove the strip and set it down on a flat surface. Wait for about 3 minutes.
- One red line (closer to the yellow end) after waiting three minutes is a POSITIVE result for the presence of fentanyl. Two red lines is a NEGATIVE result.
- The 2nd red line may be significantly lighter than the 1st red line. If you can see it at all after waiting three minutes, no matter how faint, it is still a negative result.
- No red lines (or one red line closer to the dotted end) means the test is invalid. Usually this happens because the liquid did not travel far enough up the test strip.
IMPORTANT! Sometimes a very faint red line will initially appear in the lower area (near the dots) then quickly fade away. Do NOT confuse this with a negative result. Always wait three minutes before interpreting the results.
Getting Your Powder Back
Fentanyl strip testing does NOT destroy your drugs.
You can get your powder back by evaporating away the water. There are many ways to do this, but one of the most popular ways is pouring the water into an ovenproof flat-bottomed glass or ceramic dish and heating it. The most popular method is using an oven.
- Put the pan in the oven on the lowest heat setting, no higher than 107 degrees C (225 degrees F).
- Keep the oven door cracked and keep a close eye on the pan. This process can take minutes to hours depending on how much water you’re evaporating.
- When all the water has evaporated, a film/residue will appear on the bottom of the pan. Take the pan out and let it cool. This residue usually looks a bit like a thin layer of ice or splotchy crystalline patterns.
- Scrape up the residue using a straight razor or other sharp tool. If it’s not fully dry, your powder might be a little tacky or goopy.
DISCLAIMERS:
- No fentanyl test strip on the market can detect every fentanyl analog.
- At the moment, there are no strips that can detect non-fentanyl synthetic opioids like isotonitazene.
