Again during the second debate many people on Twitter noticed that Trump again was "sniffing" a lot, something he did a lot in the first debate as well. Now the first time I could understand, maybe he had a flu ... but two debates in a row? He doesn't do the "sniffing" during his regular campaign speeches. Seems kinda strange.

Star Wars actress and infamous coke user during the 70s Carrie Fisher has said it's definitely the sign of a coke head. Cocaine use is/was rampant on Wall Street especially during the 80s (Trump's business hey day). I wonder if he needs the coke to deal with the pressure of the debates. 

Sorry, but it anyone that his high will make it obvious. 

No, there is no way he would have been as composed as he was if he was on coke, but the sniffing is odd, myself and a mate suggested playing a Donald Trump sniffing Drinking game... but we figured if we had gone ahead with it we would have both been dead by the second question.

Not if you use just a bit and are a regular coke user or have built up a tolerance. 

Could also just be a nervous habit.  There's enough legit reasons to criticize Trump that there is no need to grasp at straws.

I think it's kinda funny actually, just wondering what's up. 

That's a really big claim with a simple nose action as evidence. I myself sniff a lot because I'm allergic to... fucking oxygen, it feels; I've never had cocaine though.
