I don't recall ever needing to kill my buzz on purpose, but then again, I've been smoking for so long that I'm perfectly capable of functioning in society with a good buzz going on and nobody is ever able to tell. (Even my parents & in-laws on the rare occasion that I visit them. :jointsmile

Still, if it were something that I absolutely had to do, I'd probably just eat a ton of food and/or take a cold shower. Regardless of whether or not I want to, after satisfying a case of the screaming munchies, I'm almost always left sober as a judge at the end.
