They spit a chemical deterrents, such as the regurgitation and defecation of sticky, obnoxious-smelling fluids, are employed by many species of grasshoppers. A few species produce a stinking glandular excretion which effectively repels predators as large as geckos, jays, domestic cats, and monkeys. Certain species sequester toxic chemicals from their plantfood and predators ingesting them become ill. Most of the toxic species of grasshoppers have conspicuous vivid warning colors which predators learn to avoid. Some nontoxic species of grasshopper mimic the color of toxic species so that predators also avoid them.

Tabacco
Grasshoppers do not spit tobacco. The only way to spit tobacco is to chew tobacco, which grasshoppers do not. However, they do spit as a defense mechanism.
Yes grasshoppers sometimes spit out a black or brown colored liquid. This is thought by scientists to be a defense mechanism used to fend off ist predators.

Yes

They only spit if you are teasing them by sticking your face close to them, or mistreating them in some way. This is seen as offensive and a challenge to a llama, and as a defense they will spit.
No, but the camel does use it's spit as a defense method.
Many grasshoppers have five eyes as a defense mechanism. This allows them to see farther and wider, allowing them to evade predators.
Horned lizards spray blood from the corners of their eyes in self defense. Camels sometimes spit, not always in self defense, but sometimes it is in self defense. Chinchillas spray in self defense. Some snakes spit in self defense, and so do cats. Skunks spray a liquid from their anal sacs in self defense.
It was often thought that it was chewed tobacco (or other food, grass, etc.), because they were found as pests in tobacco plantations. However, it is merely a chemical produced as a defense mechanism.
