Richard Armitage at The Hobbit: Desolation of Smaug World Premiere in LA 

And precisely why do you call bullshit on the idea that someone in this world has never done drugs? Dude, I have never done drugs in my life and I am 3 years younger than Richard. O.o

He speaks about it entirely too carefully.

Honestly, it is at best extremely rude to accuse someone of lying, particularly when you don't know him, you've never met him, and (like most of us) you likely never will meet him. He speaks carefully about a lot of things, that doesn't mean anything beyond the fact that he is thoughtful with his words.
