Risk assessment

This felt does not contain LSD, but 25B-NBOMe. This substance can cause peripheral vasoconstriction and has been linked to some deaths in Europe. Of particular concern is that the uptake and breakdown of this substance can vary greatly from person to person. NBOMe compounds belong to the group of phenethylamines. Typical for phenylethylamines is an increased perception of digestion and the intestine (gastrointestinal sensation) as well as a strongly sensitized sense of touch. Visual effects occur, but are less prominent than with LSD. According to user reports, 25x-NBOMe compounds have different effects from time to time, so the effect cannot be predicted.

Unlike LSD, felts containing NBOMe have a bitter taste. 25B-NBOMe has a more direct and faster effect when absorbed sublingually (under the tongue) through the mucous membranes. If the substance is taken orally (swallowed), there may be a weaker and/or delayed effect. As a result, there is a risk of post-dosing and unintentional overdosing. Due to the complex substance absorption, 25B-NBOMe should never be re-dosed. Due to the difficult handling and also because the substances are hardly researched, we advise against consumption!

Alert level

Safer Use


Have your substances tested in a Drug Checking


If you do not have the possibility to have substances analysed, test a quarter or a third of the felt at the most, as felts are in circulation in very different dosages.


Pay attention to set and setting. Consume only in places where you feel comfortable and avoid mixed use.

Wait and see

Wait 3 hours after ingestion, as there are always felts with unexpected active ingredients in circulation, which can have a later onset of action.
