What's in our food is written on the packaging. This makes it clear what's inside. This is not at all clear with psychoactive substances from the black market. Because there are no rules, ingredient lists or controls! That's why it's easy to add extenders to substances. But - what are extenders anyway? Why are they used? And how can they work? In our video, we summarise what you need to look out for and how you can reduce risks. You can find the whole video on YouTube - link in the link tree.
If you have any questions, please contact the checkit! team :)
This video was created in co-operation with checkit! and the Institute for Addiction Prevention of the Addiction and Drug Coordination Vienna. Animation and graphics by Polarfux.

In Vienna, the addition of the synthetic opioid fentanyl was detected in a sample delivered as heroin.
DUE TO THE HIGH POTENCY OF SYNTHETIC OPIOIDS AND THE INCREASED RISK OF OVERDOSES, WE STRONGLY ADVISE AGAINST THEIR USE!
💡 Fentanyl is a synthetic opioid that is around 50 times more potent than heroin and is therefore extremely difficult to dose. Consumption can lead to a reduction in respiratory rate and even life-threatening respiratory depression! Across Europe, reports of drug-related emergencies involving synthetic opioids have been on the rise for a few years now.
The potency of synthetic opioids is sometimes many times higher than that of morphine. Some are thousands to ten thousand times more effective than morphine. This makes it difficult or even impossible to find a dosage that leads to the desired effects. Sometimes they are sold as synthetic opioids, sometimes they are detected as an unexpected admixture (e.g. in heroin, oxycodone tablets or benzodiazepine tablets).
‼️ Even small amounts can trigger life-threatening overdose symptoms.
💡 RISK REDUCTION - Use drug checking if possible. The appearance of a substance says nothing about the ingredients. - If you don't have the option of drug checking, consume small amounts and wait to see the effects. - Don't consume alone and take turns consuming. - Call the emergency services (144) if you or someone else is unwell. - Avoid mixed consumption, especially with other "downers".
🔀 MIXED CONSUMPTION As with all opioids, consumption together with other depressant substances ("downers") increases the risk of overdose, which can lead to life-threatening respiratory depression. Together with stimulant substances (e.g. cocaine), the body is heavily burdened by the opposite effects. This can lead to cardiovascular failure.
You can find more information on our website: https://checkit.wien/substanz/synthetische-opioide/...
If you consume several substances together or within a short period of time, this can be particularly stressful and risky for your body and mind. This is because the effects can reinforce, weaken or even change each other. If you consume cocaine together with alcohol, the following happens, among other things:
Cocaethylene forms in the liver when it is broken down. It is more toxic, i.e. more poisonous, and the risk of cardiac arrhythmia is higher than if you only consume cocaine. Cocaethylene also has a longer half-life than cocaine. This means that your body needs longer to break it down again.
Possible excipients contained in cocaine can also lead to interactions and increase the risk of adverse effects. In recent months, procaine has been increasingly detected as an extender in cocaine samples -> all the more reason to use drug checking
The combination of cocaine and alcohol also leads to an underestimation of the effects of alcohol. You feel sober and don't realise the effects of the alcohol, even though you are drunk. Overconfidence and loss of control increase the dangers for you, friends and acquaintances, as well as other road users, especially in road traffic.

Our current warnings for calendar week 44 are online!

More than one in three cocaine samples contained one or more extenders in addition to cocaine, including procaine in many cases. In one sample submitted for analysis as ketamine, 3-CMC (clophedrone) was identified instead. Three samples submitted for analysis as either 3-MMC and mephedrone (4-MMC) contained a different cathinone instead of the expected substance: 2-MMC or 3-CMC (clophedrone).
