1 In saliva: Nicotine stays in your saliva up to 4 days.  In hair: nicotine can stay in hair for months instead of for days. It is more surprised that many hair tests can detect nicotine for up to a year. However, nicotine is normally found within 1-3 months after you stop smoking.

A standard bottle is 750ml. A 'standard' glass is 125ml = 6 servings. That is the glass used when they say 'one serving of wine is one unit of alcohol' as 125ml @ 10 % = 1.2 units. Of course, most wine isn't 12% and servings aren't 125ml so the actual unit consumed is much higher... a 125ml serving is pretty stingy. I have read 'seven glasses from a bottle' but that would be very miserly: 107ml... Most bars or typical (measured) servings will be 175ml = 4 servings.
