Thank you so much! And I love YOU, random citizen ;D

Re: Cigarettes:

Lestat quite enjoys smoking.

He likes to do it to pester Louis, who finds cigarette smoke distasteful. Lestat also does it for the oral fixation aspect. It calms him to have a cigarette to fidget with, and it gives him a reason to carry a cool lighter around. 

Louis dislikes smoking bc he has a much stronger sense of smell. The Scent Gift, if you will and yet, he doesn’t mind sitting around in sewers in the movie… maybe he’s punishing himself extra when he was doing that…

Also:

• Lestat has perfected the art of smoke-rings, too. 
• Cloves are also something Lestat likes, for their scent.
• You didn’t ask this specifically but I was thinking about it: marijuana and other smoked drugs have to be decanted in the blood of their victims for it to have any effect on them, but that doesn’t apply to cancer. Conveniently, vampire physiology setup rejects tumorous growths but accepts hallucinogenics!
