Is Dicyanin Banned by the Government for Clandestine Use

“Could the use of dicyanin by practitioners be done clandestiny outside of peer review It's been a long time since it's discovery and use in such manners and has the government banned this chemical”
No government ban
Confidence: High Checked on May 21, 2026

Summary

The United States has not prohibited dicyanin; it is still employed in laboratory settings and is not listed as a controlled substance. Claims that the government secretly banned the dye because of alleged supernatural properties are unfounded. Consequently, practitioners could use dicyanin outside of peer‑reviewed research, though no scientific evidence supports its purported paranormal effects.
