New synthetic drugs: why their identification is difficult

Why is their identification complex?

The market evolves rapidly. One molecule can be replaced by a close variant, while a product sold under a known name may contain another substance, several molecules, or an unexpected concentration.

NPS can come in the form of powder, tablet, vaping liquid, impregnated herb, candy, capsule, or fake medicine. Appearance and brand name do not reveal the actual composition.

What major families should be known?

• Synthetic cannabinoids: effects sometimes much more unpredictable than those of cannabis;
• Synthetic cathinones: stimulant products that can resemble cocaine, MDMA, or amphetamines;
• Synthetic opioids: major risk of respiratory depression and overdose;
• Dissociatives: disorientation, loss of coordination, and altered consciousness;
• Emerging adulterants and sedatives: substances added to other products, sometimes without the user’s knowledge.

Which risks are particularly concerning?

Potency, duration, and interactions can be difficult to anticipate. Mixing with alcohol, medications, or other drugs further increases unpredictability.

• tachycardia, chest pain, or hypertension;
• panic, paranoia, hallucinations, or severe agitation;
• seizures, hyperthermia, or loss of consciousness;
• deep drowsiness or slowed breathing;
• compulsive use and closely repeated intakes.

Why can a standard test be negative?

Each rapid test searches for a specific list of substances or families. A THC, cocaine, or amphetamines panel does not automatically cover synthetic cannabinoids, cathinones, new opioids, or dissociatives.

A negative result can also be explained by sampling too early or too late, a concentration below the threshold, a molecule not recognized by the device, or an inadequate sample.

What role does targeted screening play?

A targeted test can be a guidance tool when a particular family is suspected. It is necessary to check the instructions, panel, threshold, cross-reactions, and reading conditions. A rapid positive result remains presumptive.

When the issue is medical, judicial, or professional, an appropriate toxicological confirmation may be necessary. Faced with an unknown product, laboratory analysis remains more informative than a series of randomly chosen tests.

Prevent without dramatizing

Prevention relies on reliable information, risk reduction, access to care, and the ability to recognize an emergency. Parents, institutions, companies, and event organizers should avoid presenting a system as universal.
