Introduction:
Thai veterinarians are active participation in tobacco control.

Objectives:
Nicotine and second-handed smoke knowledge, opinion and practice among Thai veterinarians (VET) was surveyed.

Methods:
Self-reported questionnaire developed by the research team after systematic review. Convenience sampling was applied to 151 Thai veterinarians.

Results:
Results revealed that most of them were practice in 29 provinces. The majority of them were lived in nearby Bangkok. The average experience was 9.12 years. Minimally was less than 1 year and the maximum was 60 years. Most of them were a none-smoker. Only 10 percent were smokers. Ninety-six percent had no experience to treating dogs and cats those received nicotine poisoning or second-handed smoke (SHS). Among veterinarians who experienced to taking care pets from nicotine poisoning/toxin or second-handed smoke claimed that pet got nicotine by accident or received second handed smoke from the owner or family member (25 persons). In addition, knowledge of VET showed that they had only 4.76 from 13 scores of knowledge (min = 0, max = 13). For VET opinion, they thought that they agreed that VET should protect and take care pets from nicotine toxin and SHS (mean = 59.51, SD = 31.22, min = 0%, max = 100%). From a practical point in the case of treatment for nicotine victims 15.4% (22 person) would like intravenous (IV) fluid and oxygen therapy. Follow by 9.8% prescribed toxin absorbance, IV application, 7.7% will apply 3 interventions included toxic absorbance, IV administration and oxygenation. Additionally, some willing to apply 4 interventions include toxin absorbance, IV, oxygenation and gastric lavage equal to 5 interventions integrated by toxin absorbance, IV, oxygenation, gastric lavage and sedative.

Conclusions:
Recommendation: Veterinarians should be educated on nicotine toxicity and raise positive awareness to protect and take care pets from nicotine harmfulness and SHS. Clinical practice guidelines on nicotine toxicity/SHS approaches should be created.
