Synthetic Abuse and Labeling of Toxic Substances Act of 2015 or the SALTS Act

Amends the Controlled Substances Act to authorize evidence related to the following factors to be considered in determining whether a controlled substance analogue was intended for human consumption:

• the marketing, advertising, and labeling of the substance;
• the known efficacy or usefulness of the substance for the marketed, advertised, or labeled purpose;
• the difference between the price at which the substance is sold and the price at which the substance it is purported to be or advertised as is normally sold;
• the diversion of the substance from legitimate channels and the clandestine importation, manufacture, or distribution of the substance; and
• whether the defendant knew or should have known that the substance was intended to be consumed by injection, inhalation, ingestion, or any other immediate means.

Declares that the existence of evidence that a substance was not marketed, advertised, or labeled for human consumption shall not preclude the government from establishing, based on all the evidence, that the substance was intended for human consumption.
