This is the list of Schedule I controlled substances in the United States as defined by the Controlled Substances Act. [1] The following findings are required for substances to be placed in this schedule: [2]
NIOSH was created by the Occupational Safety and Health Act of 1970 [27] and began operating in May 1971. [25] It was originally part of the Health Services and Mental Health Administration, and was transferred into what was then called the Center for Disease Control (CDC) in 1973.

Tier 2 banding is also incorporated into the NIOSH OEB e-tool but can take hours instead of minutes to complete for a given chemical. However, the resulting band is considered more robust than a Tier 1 band due to the in-depth retrieval of published data. [7] NIOSH recommends users complete at least the Tier 2 process to produce reliable OEBs.
Category 1: Substances known to be carcinogenic to humans. Category 2: Substances which should be regarded as if they are carcinogenic to humans. Category 3: Substances which cause concern for humans, owing to possible carcinogenic effects but in respect of which the available information is not adequate for making a satisfactory assessment.
IARC group 1 Carcinogens are substances, chemical mixtures, and exposure circumstances which have been classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC). [1] This category is used when there is sufficient evidence of carcinogenicity in humans.
Generic drugs are versions of brand-name drugs that share active ingredients. There are some associated out-of-pocket costs with PDPs, but in 2024, Medicare will not allow private companies to set ...
Genotoxicity might involve carcinogenicity, the ability to cause cancer in animal models, humans or both; teratogenicity, which is the ability to cause defects on fetal development or fetal malformation; and lastly hazardous drugs are known to have the potential to cause fertility impairment, which is a major concern for most clinicians.

The NIOSH definition is the only definition that includes drug vapors. [8] NIOSH considers the containment of vapor extremely important, such that in September 2015, NIOSH issued a Testing Protocol to assess the effectiveness of closed systems. [9] NIOSH developed and tested five CSTDs to assess its "closeness". Two of the five CSTDs tested passed.
