Average 40% difference between declaration and effective content for LSD felts

In 2021, 60 LSD felts tested at the DIZ Zurich had an active substance content. Consumers had received this information from the dealers. Our internal evaluation has now shown that these declarations differ in part very strongly from the actual content.

On average, the felts were declared to contain around 170 micrograms when sold. The laboratory analyses, however, showed that the felts contained on average about 105 micrograms. This means that many users assume that they consume much higher doses of LSD than is actually the case. Especially if the users then consume LSD that has been tested, this can lead to them consuming too high doses of LSD. This in turn increases the risk of experiencing an unpleasant trip. Especially when dealing with tested LSD, one should approach the desired dose slowly.
