Research corpus coverage

Ethnobotanical / entheogenicPet safety

Chemistry notes

  • Principal reported constituents include nicotine, nornicotine; broad class: nicotinic acetylcholine receptor agonists.

Uses & Evidence

Traditional / historical use

Documented traditional use — not a claim of established efficacy.

No traditional-use records in this corpus.

Modern evidence

  • Often confused with N. tabacum; nicotine content can be much higher and preparations vary.

Cats

  • High risk

    The page’s general toxicity-to-pets text describes tobacco (Nicotiana) poisoning as causing initial low heart and respiratory rates, followed by overstimulation, uncontrolled urination or defecation, tremors, seizures, paralysis, and death; it does not separately assign a toxicity designation to cats.

    MODERATE · veterinary_hospital_guidance · E-cigarettes and Pet Safety | VCA Animal Hospitals

    The page refers to tobacco-derived nicotine but does not identify the botanical tobacco species; applicability to Nicotiana rustica is therefore not species-specific.

  • Ingestion of nicotine-containing tobacco products, including chewing tobacco, cigarettes, cigars, bidis, nicotine-replacement products, and cigarette butts, may be toxic to cats and dogs.

    HIGH · poison_control_database · Nicotine & Tobacco | American College of Veterinary Pharmacists

    The page discusses tobacco and nicotine products generally and does not identify Nicotiana rustica botanically or distinguish it from Nicotiana tabacum.

  • Nicotine ingestion may cause acute toxicosis in cats, but the page states that no established toxic threshold exists for cats.

    HIGH · poison_control_database · Nicotine & Tobacco | American College of Veterinary Pharmacists

    The page provides no cat-specific dose or threshold and does not botanically distinguish Nicotiana rustica from other tobacco sources.

  • Environmental tobacco smoke exposure was associated with increased risk of malignant lymphoma in pet cats.

    MODERATE · poison_control_database · Tobacco Is Toxic To Dogs | Pet Poison Helpline®

    The clinical signs are presented in general pet text rather than separately attributed to cats; the page discusses Nicotiana generally and does not provide species-specific evidence for Nicotiana rustica.
