How to Detect LSD in Blotters

I would like to know how to detect LSD in blotters. Is this possible? I am concerned about adulterations with NBOMEs. My country does not allow Drug Checking Services. Thank yoh

Over the past few years, there have been reports of the adulteration of blotting papers allegedly containing LSD. While LSD is a relatively safe psychedelic, other substances such as 25-i-NBOMe and BromoDragonfly are much more dangerous on an organic level.

It’s worth noting that LSD is a highly sensitive chemical compound that can easily decompose under adverse conditions. Exposure to light, heat, humidity, and air can accelerate the degradation process. This results in most LSD blotters degrading within 5-10 years.

To ensure the safety of the substance, it’s ideal to have samples analyzed in a Drug Checking Service. However, this option may not always be available. Nevertheless, there is a simple way to detect the presence of LSD in a blotter or liquid.

LSD has a unique characteristic of fluorescing under UV light. A black light,(known as UV-A light, Wood’s lamp, or ultraviolet light), emits long-wave ultraviolet light (UV-A). It’s the type of bulb used to produce fluorescent effects on clothing or paint . You can find it in any lighting shop for a few dollars or euros.

To conduct the test, prepare a small sample of the substance you want to test, such as a small piece of blotting paper or a small amount of liquid. The undecorated back of the LSD blotters is the most suitable.

Turn off the lights in the room and turn on the UV lamp. Ensure that the UV lamp emits light at a wavelength of about 365 nm.

Bring the sample close to the UV lamp and observe if it emits a bright bluish-white fluorescence. LSD typically emits a bright blue-white fluorescence under UV light.

It’s important to note that this method can only confirm or rule out the presence of LSD and cannot detect adulterants or degraded samples. In cases where Drug Checking Services are unavailable, this test can provide an initial indication of the substance’s identity.
