Risk assessment

This sample purchased online, declared as a THC vape and labeled "VADER", contained THCthe cannabinoid Delta-8-THC (∆8-THC) as well as several non-identifiable THC isomers.

‍Delta-8-THC(∆8-THC) is a psychoactive cannabinoid that produces a similar intoxicating effect to delta-9-THC (the "classic" THC), but is less potent. No studies are available on the short-term and long-term side effects of delta-8-THC. The possible interaction with THC and CBD is completely unknown. In addition, several unidentifiable THC isomers were detected in the sample, which indicate impure production.

There are currently various hashish, vape and cannabis samples in circulation that contain delta-8-THC but have been declared as THC. Newly purchased products must be tested and analyzed before use!

Alert level

Safer Use


With newly purchased, unfamiliar cannabis products, it is advisable to test only a small amount the first time (take two or three puffs) and then wait about 15 minutes for the effect to develop. If the effect is unusual, do not continue to use the product!

Mixed use

Avoid mixed use. Mixed use with other substances (including alcohol or medications) is very risky because of the unpredictable and still unknown interactions. Avoid mixed use with MAO inhibitors, opioids or tranquilizers.

Mix well

Mix your cannabis products well before consumption (ideally use a grinder) to avoid a high concentration of possible synthetic cannabinoids on individual flower parts. Particular care should be taken with residual material that has fallen off the outer parts of the flower, as this is often likely to contain a particularly high concentration of synthetic cannabinoids.
