Synthetic opioid discovered in Smoking mixture

The smoking mixture sold as "Krypton" contains, according to the manufacturer's specifications kratom leaves and extracts. The effect is described as stimulating and relaxing.

The Institute for Forensic Medicine in Freiburg, Germany, has now analyzed the product. Besides caffeine, the synthetic opioid O-Desmethyltramadol is identified. This is a breakdown product of tramadol, an opioid painkiller which is prescribed with moderate to severe pain. After the consumption of O-Desmethyltramadol it turns into tramadol in the liver and because of this it is much more potent than tramadol itself.

Like with "Spice" this is once again shows consumers need to be careful with products that are presented as smoking mixtures, since no assumption can be made that the ingredients listed on the product actually contained correspond. In this case, moreover, we are not dealing with synthetic cannabinoids, like with Spice but with a synthetic opioid. Due to the high potency of O-Desmethyltramadol there is an increased risk of overdose and, subsequently, respiratory paralysis. Based upon the high risk in regard to the addictive potential of opioids, we strongly recommend against the consumption of this 'herbal blend'.
