When sold as "Ecstasy", tablets containing 2C-B often contain about 5&nbsp;mg of the drug, an amount which produces stimulatory effects that mimic the effects of MDMA; in contrast, tablets marketed as 2C-B have larger quantities of the drug (10–20&nbsp;mg) which cause [[hallucinogen]]ic effects.<ref name="Netherlands 2c-b emergence">{{cite journal |vauthors=de Boer D, Gijzels MJ, Bosman IJ, Maes RA |year=1999 |title=More data about the new psychoactive drug 2C-B |journal=Journal of Analytical Toxicology |volume=23 |issue=3 |pages=227–8 |doi=10.1093/jat/23.3.227 |pmid=10369336 |doi-access=free}}</ref>
