Blotter paper is sometimes used as a medium for distributing research chemicals, which are synthetic compounds designed for scientific research purposes. In the context of research chemicals, blotter paper may be soaked in a solution containing a specific compound, and then cut into small squares or tabs, each of which contains a measured dose of the research chemical. However, it is important to note that the use and distribution of research chemicals may be subject to strict regulations and restrictions, and the misuse of these substances can pose significant health risks. Research chemicals should only be handled by qualified professionals in controlled laboratory settings and should not be used for recreational purposes.
