Prime Minister Justin Trudeau marked 100 days in office Friday by holding a Q&A session on Twitter, where he briefly responded to a broad mix of serious and silly questions from Canadians.

Twitter users submitted their questions using the hashtags #First100 and #100jours, and Trudeau selected tweets to answer from Twitter's Canadian headquarters in Toronto.

Trudeau answered 27 question out of the more than 14,000 submitted in the 24 hours leading up to the Q&A, according to Twitter Canada.

Below are some of the topics he addressed.

Marijuana

Trudeau dismissed a suggestion that his government hasn't been" serious" about legalizing marijuana, and insisted that they're taking the time needed to get the legislation right.

He also rejected the possibility of simply decriminalizing marijuana, saying that it "does nothing to protect kids from pot, and keeps money flowing to gangs, criminals and gun-runners."

Voting and the Senate

On the matter of the Senate, Trudeau said he plans to "remove partisanship and patronage," and "make it more independent and accountable," without reopening the Constitution.

Trudeau used a video response to answer a question about making ex-pats eligible to vote in Canada.

"It's something we're looking at," Trudeau said. "It's not going to be easy. It's a little complicated because of the fact that you vote in ridings, and not necessarily just for a party or a leader. But I know we're working hard on making it happen."

Other top issues

Trudeau addressed a number of questions about his campaign pledges during the Q&A.

Lighter fare

In addressing some of the lighter questions, Trudeau declared himself a Montreal Canadiens fan, praised the new "Star Wars" movie for not including Jar-Jar Binks, and labeled the hot dog a sandwich.

Trudeau also responded to a question from a Grade 5-6 class in Saskatchewan, about how long he's wanted to be prime minister.

"I was raised to know that I need to make a difference," Trudeau said in his video response. "The goal was making a difference and serving my community as best I could, and it ended up being politics and as prime minister, just like my dad."
