The market for LSD is very polluted due to the fact that the chemicals needed for it are difficult to obtain. Many times, instead of LSD on a blotter, there will be research chemicals such as 25B-NBOME, 25I-NBOME amongst many others. These adulterants in drugs can have serious side-effects such as nausea, anxiety, insomnia and in the worst case even death. EZ Test for LSD is a quick and easy to use test kit that can tell whether your sample contains LSD or another indole. It is an effective means of adulterants and other potentially harmful substances which are often found in street drugs.
When testing blotter LSD the colour will probably not be as vibrant as when using a more concentrated form of sample, like a crystal or a liquid. Nevertheless, the colour will show up, just give it some time (3 minutes or so)!
