Follow UK immigration and follow UK scientific research achievements: The University of Birmingham in the UK has invented a new method that can determine whether someone has smoked within the last 3 days in just 1 minute, and can measure nicotine intake in 6 minutes.
In this test, known as "saliva smoking screening," testers determine whether a person has smoked by identifying the presence of cotinine, a nicotine metabolite, in the participant's saliva. Due to the different types of cigarettes and individual smoking habits, this test cannot currently determine exactly how many cigarettes a participant has smoked, but it can measure how much nicotine the participant has inhaled within 3 days.
Dr. Graham Cope, a senior research fellow at the University of Birmingham, stated that this method can effectively help smokers quit their addiction.
