Current warnings September 2018
In Sep
tember 2018, we tested a number of substances that pose a particular health risk. In addition to some (very) high-dose ecstasy tablets, we also tested Unknown substances were discovered in various samples. Three unknown substances were found alongside LSD in a sample submitted as LSD. Furthermore, one unknown substance was detected in each of two amphetamine samples alongside amphetamine and caffeine, as well as in one sample submitted for analysis as O-desmethyltramadol and one as 4-HO-MET. In one sample submitted for analysis as mephedrone, the new psychoactive substances 4-CEC (4-chloroethcathinone) and 4-CMC (Clephedrone) identified.
Under the following link, all samples that have been collected since the last warnings until today at checkit! were analysed and contained new psychoactive substances and/or were classified as high doses, unexpected or of particular health concern.

In addition to some high to very high doses of ecstasy tablets, the new psychoactive substance Methylpentedrone was identified in a sample submitted for analysis as MDMA. One or more unknown substance/s were detected in one sample given as 4-HO-MET, one as LSD and one as mephedrone.

Current warnings July / August 2018
Warning: Fentanyl in heroin
checkit! has developed a "China White" - Heroin sample was identified as having a particularly harmful composition.
In addition to an above-average content of diacetylmorphine, the sample also contained 6-monoacetylmorphine, caffeine, noscapine, an unknown substance and the highly potent synthetic opioid fentanyl.
Fentanyl is a synthetic opioid and about one hundred times more potent than morphine. Fentanyl has already been associated with numerous life-threatening overdoses, which have also led to deaths as a result of respiratory depression. Mixed use with other centrally depressant substances (as contained in this sample) is strongly discouraged. Furthermore, serious interactions with a number of medications are known.
Reports of synthetic opioids are increasing across Europe. Over the course of the last year, checkit! has also occasionally detected synthetic opioids in various substance samples.
The term "synthetic opioids" refers to substances that are produced synthetically and have a similar effect to natural opiates (e.g. morphine) or heroin. The potency of these substances is often many times higher than that of morphine, which makes dosing difficult or even impossible without a laboratory scale. Even careless handling of some substances can be life-threatening.
China White is often used in online forums and in the literature as a name for a synthetic opioid, the fentanyl analogue α-methylfentanyl, but also for mixtures of heroin with synthetic opioids.
Due to the above-mentioned high potency of synthetic opioids and the increased risk of respiratory depression (especially through the combination of two centrally depressant substances), we strongly advise against their use.

Current warnings June 2018
Since the beginning of June 2018, we have tested a number of substances that pose a particular health risk. In addition to caffeine, a supposed ecstasy tablet contained the new psychoactive substances 4-CMC (Clephedrone), 4-CEC (4-chloroethcathinone) and 4-BEC (4-bromoethcathinone) was identified. In three further samples submitted for analysis as ecstasy, in addition to the expected active substance MDMA, a unknown substance detected. Two samples submitted as mephedrone showed the new psychoactive substances 4-CMC and 4-CEC resp. 4-CMC, 4-CEC and 4-BEC. In addition, an alleged speed sample instead of the expected amphetamine Methamphetamine identified.
Under the following link, all samples that have been submitted to us in the period from 01.06.2018 until today checkit! were analysed and contained new psychoactive substances and/or were classified as high doses, unexpected or of particular health concern.
Current warnings May 2018
Since the beginning of May 2018, we have tested a number of substances of particular health concern. In a sample submitted for analysis as mephedrone, the three new psychoactive substances 4-CEC (4-chloroethcathinone), 4-CMC (Clephedrone) and 4-BEC (4-bromoethcathinone) was identified. In another sample submitted for analysis as mephedrone, a previously unknown substance was detected in addition to mephedrone. Caffeine was found as an extender in various samples (speed, MDMA, ketamine, cocaine, 2C-B). Many of the samples submitted for analysis as cocaine had a high cocaine content and admixtures of levamisole.
Current warnings April 2018
Since the beginning of April 2018, we have tested a number of substances that pose a particular health risk. In addition to some (very) high-dose ecstasy tablets, various new psychoactive substances were detected. In two as Mephedrone samples submitted for analysis were found to contain the new psychoactive substance 4-Chloroethcathinone (4-CEC) proven. For the first time checkit! the hallucinogenic AL-LAD detected in a sample submitted as such.
Current warnings March 2018
Since the beginning of March 2018, we have tested a number of substances of particular health concern. In addition to a series of (very) high-dose ecstasy tablets, one supposed ecstasy tablet contained MDMA as well as the expected MDMA, Methylone and Dimethylone (bk-MDDMA). Almost all samples submitted for analysis as alleged speed contained amphetamine Caffeine in different proportions.
