I bought a tin of McClelland's Christmas Cheer 2016 about a year ago. I opened it and after my first bowl I put it away because of the over powering smell of ketchup and I ended up forgetting about it. I was organizing my tobacco cellar and I came across it. I am pleasantly surprised that the over powering smell of ketchup is pretty much gone. My question is, will it be safe to smoke after being open so long in the tin?
