Risk assessment

In a white powder ordered on the darknet and declared as heroin, the synthetic opioid fentanyl and caffeine were found instead of heroin .

Fentanyl is about 50 times more potent than heroin and can lead to life-threatening conditions, including respiratory depression, even at very low doses. If mistaken for heroin, this risk is massively amplified, since even people with opioid tolerance very quickly take much too high doses.

This is the first time that fentanyl has been detected in a heroin sample in Switzerland. Currently, it is not expected that the substance will be found on the street in Switzerland, as the substance was obtained via a darknet channel. Nevertheless, we currently recommend extreme caution when handling heroin and testing small quantities first.

With powders and crystals, dangerous misdeclarations occur time and again; therefore, be sure to have these substances analyzed in a drug check.

Consumption of this sample is strongly discouraged.

Analysis

Have your substances tested in a Drug Checking

Testing

If you do not have the possibility to have substances analysed, always test a small amount to avoid overdoses.

Wait and see

Wait 2 hours after oral intake, as there are always powders / crystals in circulation with unexpected active ingredients, which can have a later onset of action.

Utensils

Always use your own sniffing utensils when applying powders nasally (sniffing) to avoid infecting yourself or others with diseases.
