Pink Cocaine / Tusi

Legal status: Pink cocaine (tusi) is not scheduled as such; it is a variable mixture (typically ketamine + MDMA) prosecuted through its constituents — both MDMA and ketamine are controlled substances under the Narcotics Control Act, which reaches any preparation containing a controlled substance. Because the blend varies batch to batch, exposure follows the most-severely-controlled detected component.
Consequences if caught: Possession, use and supply are criminal offences under the Narcotics Control Act, punishable by imprisonment and charged on whichever constituent is detected.
If prescribed / medical: No lawful supply of the mixture; ketamine is a controlled medicine used under strict medical supervision, while MDMA has no marketed medical use.
Documentation: Sold as an unregulated party powder; because the makeup varies batch to batch, buyers cannot know its constituents, so legal exposure under the Narcotics Control Act is unknowable at purchase.

Documentation: Butylscopolamine/scopolamine products are registered in the MFDS (nedrug) drug database; carried lawfully.
