Donald Trump’s repetitive sniffling and water-sipping during the first presidential debate Monday night caused the Twitterverse to speculate if he was on something.

“Notice Trump sniffling all the time. Coke user?” tweeted former Vermont Gov. Howard Dean, a doctor and a former Democratic presidential candidate.

Notice Trump sniffing all the time. Coke user?

From there, the hashtag #CocaineTrump took off, with the Twitterati chiming in with their own thoughts on the Republican nominee’s sniffles.  

WHO WON THE DEBATE?
HILLARY: 62%
TRUMP: 27%
COCAINE: 11%#CocaineTrump#Sniffles

If #CocaineTrump is his new business, its going to fail, too. Although he wouldn’t have to pay taxes on it either. https://t.co/IbI1L0FhpD

“To be president of this country, you need to have tremendous amounts of cocaine, I mean, er, stamina.” #debatenight #cocainetrump

However, not everyone appreciated the former governor’s tweet.

Kevin Corke, Fox News’ White House correspondent, called Dean’s remark “unbecoming.”

@GovHowardDean unbecoming Governor. Americans expect better from you.

Matt Rosoff, an executive editor at BusinessInsider, rebutted Dean’s assertion.

@GovHowardDean He’s 70 dude. He’d be dead.

Suzanne Mulet, the Salt Lake County GOP chairwoman, also had a diagnosis. 

@GovHowardDean @NormanAtlantic4 Maybe he caught Hillary’s pneumonia.
