Are cigarettes bad for your health?

Yes, most definitely!

The main problem with smoking is that it screws up you lungs, eating it would not do that. But still, I wont advise it, at all. Nicotine also, if ingested, causes diarrhea and nausea. Enough nicotine at once can cause death.

Just use a patch if you want to quit or other drugs that your doctor would advise.

If you want to start by eating your cigarettes rather don't start at all or just do what everyone does that smokes, smoke it.

Eating cigarettes can be WAY worse than smoking because you can overdose on nicotine. Nicotine is a poison. If you eat enough cigarettes you can DIE. 2mg of Nicotine, or 2 cigarettes (depending on what kind) is enough to kill someone small, so be careful if you actually decide to eat any cigarettes.
