It's a rather nasty combination because the cannabis has lots of tar and most tobacco has tons of chemical additives added with the sole purpose to suppress coughing.

Because of those additives, tobacco+cannabis is way easier to smoke, resulting in people keeping hits in longer, which supposedly gives stronger effects but also more time for the tar to settle down in the lungs.

In that regard, it's odd how people keep on harping on about cannabis being "so much stronger than it used to be", while the tobacco industry literally spend decades and billions of $ to make their tobacco more potent, easier to smoke and as addictive as possible, by adding dozens of questionable chemicals.

At this point tobacco is probably one of the most overdesigned drugs in human history, I can't think of any other psychoactive substance that has had so much time, money and effort put into it.
