THC test

The Dope or Nope THC test, sold in the English range as Legit or Fake, shows whether a sample of cannabis or hash probably contains THC (tetrahydrocannabinol). This kit has its own routine: a small pellet goes into the ampoule before the sample.

What the THC test checks

THC is the main active substance in cannabis. The test shows whether THC is probably present in a small piece of flower or hash. It does not tell you how strong the cannabis is; FRANK notes that even smell is no reliable guide to the strength of a batch (FRANK, cannabis).

FRANK also reports that dealers sometimes cut hash with similar-looking substances or heavy materials to add weight, and that it is hard to know when this has happened. A THC result tells you THC is there; it does not tell you what else is in the piece.

The routine differs from the other kits: remove the pellet, break the ampoule, put the pellet inside, add your sample, then twist and close. The manual below shows each step.

What a result tells you, and what it does not

A Dope or Nope test is a presence test. When the liquid turns a colour that is on the chart, the sample probably contains (some of) the substance or substance family named there. That is all the colour says.

• It does not measure purity or dose. The test does not show how much of the active substance is in your sample.
• It does not see everything. Another substance that the test does not recognise can sit in the same sample.
• It does not make anything safe. A matching colour is no promise of a safe experience. No drug use is without risk.
• No reaction, or a colour that is not on the chart, means you are not dealing with the substance on the chart. You then cannot say what the sample is. It might be harmless or extremely dangerous: throw it away.

The page on reading results explains false positives, false negatives and cutting agents in more detail.

Before you start

Each pack holds one single-use test. Work on a clean, dry and stable surface in good light, and keep the leaflet with the colour chart next to you. Use only a tiny bit of your sample, about the size of a pinhead: that is what the pack asks for, and more material does not give a better reading.

The ampoule contains a strong acid. Keep it upright and point it away from your face when you break it. Use a new test for every sample: a pill from another batch or powder from another bag counts as a different sample.

This kit starts differently. First remove the small pellet, break the ampoule and put the pellet inside, then add your sample. Then twist the top and put it back on the ampoule.

Safety and storage

Using this test is at your own risk. It gives an indication of the identity of the active substance(s) and therefore cannot offer 100% certainty; no rights or guarantees can be derived from it. The liquid contains a strong acid: keep the test out of reach of children and avoid contact with eyes and skin, as it can cause irritation. If the liquid touches your skin or eyes, rinse with plenty of water.

Store the pack cool and dark, below 35 °C (95 °F), in its original packaging. The test is meant for adults (18+).
