How bad is it when one drinks water which is littered with cigarette buds?

The water was in a bottle, the bottle served as an ashtray.
The person who drank it was consumed in a computer game and thus was unaware of the water containing the (rolled) cigarette buds.
The water was a little brownish/yellowish.
I thought it would not matter so much as you will also get the nicotine in your system when you just smoke the cigarette.
Anyone has an idea as to the danger of drinking it?
