Workplace Drug Screening Q&A

A question-answering dataset for workplace drug screening — federal drug testing regulations, specimen collection, laboratory methodology, testing panels, and Medical Review Officer (MRO) procedures. Built to fine-tune a small instruction model into a domain assistant for HR professionals, employers, occupational health staff, and MROs.

Each row is a chat-formatted example:

{
  "messages": [
    {"role": "system",    "content": "You are an expert in workplace drug screening ..."},
    {"role": "user",      "content": "What is the federal urine cutoff for marijuana metabolites?"},
    {"role": "assistant", "content": "The initial test cutoff is 50 ng/mL ... \n\nSources: SAMHSA Mandatory Guidelines ..."}
  ]
}

The data combines three answer behaviors the model is meant to learn:

1. Accurate, regulation-grounded answers to on-topic drug-screening questions.
2. Grounded citations — most answers end with a Sources: line naming the governing regulation (e.g. SAMHSA Mandatory Guidelines, 88 FR 70768; 49 CFR Part 40). Citations are mapped from the source document each Q&A was written from — never invented.
3. Scope-limiting refusals — a small set of off-topic questions paired with a polite decline + redirect answer, so the model stays in its domain instead of answering unrelated requests.

Sources

Answers are derived from publicly available regulatory and reference material:

• SAMHSA Mandatory Guidelines for Federal Workplace Drug Testing Programs (Urine, 88 FR 70768; Oral Fluid, 88 FR 70814) — U.S. Government, public domain.
• DOT 49 CFR Part 40 (drug & alcohol testing procedures) — U.S. Government, public domain.
• FDA drugs-of-abuse regulation material — U.S. Government, public domain.
• StatPearls (NCBI Bookshelf: Drug Testing NBK459334, Toxicology Screening NBK499901) — licensed CC BY-NC.

Because some answers derive from StatPearls (CC BY-NC), this dataset is released under CC BY-NC 4.0: free to use for research and non-commercial purposes with attribution.

Intended use & limitations

• Intended: research, education, and non-commercial fine-tuning of domain assistants.
• Not legal or medical advice. Regulations change; always verify against the current primary source before relying on an answer operationally.
• Coverage is U.S. federal workplace drug testing. It is not exhaustive of state law or non-U.S. programs.
