The exact opposite happened to me. When I started smoking weed, I felt like I craved less. I suspect it really depends mostly on the individual.
I had a similar reaction as White_Rose where the more I consumed cannabis the less I smoked, but I had friends who were completely different. Some loved smoking "chops" which were tobacco and ground weed out of a bong. It's a gnarly headrush, but I never really felt the weed so I wasn't a fan, but I had friends who went through pipe tobacco bags for their chops. They'd chop like every hour or two and felt cigs were too weak.

It can, but only if you're the type that regularly mixes the two. Eventually it can get to the point where smoking weed makes you crave a cigarette, and where smoking a cigarette can make you crave some tree.
It definitely wouldn't happen all of a sudden, though. Addiction and forming new bad habits tend to take time and dedication.

The joint was mixed with tobacco.
