Sometimes from popular portrayals of Native American tobacco use, you can get the impression that all use was ceremonial. Was that the case or was it also used recreationally? Were there people who would be smoking a pipe every morning? Was it limited to nobility and priests? Was there chewing tobacco?
Here's a very short answer taken from Nancy Turner's book "Ancient Pathways, Ancestral Knowledge: Ethnobotany and Ecological Wisdom of Indigenous Peoples of Northwestern North America". In the Northwest, several different types of tobacco were used prior to the introduction of the more powerful tobacco brought in through European trade. The tobacco was smoked, and in parts of the coast it was chewed together with burnt clamshells, which helped activate the nicotine. It was primarily a spiritual or ceremonial substance, used at funerals and feasts, and was quite labor intensive to make, involving a more complicated process to prepare for consumption. It was used by many people, but definitely more by shamans or people with reason to be involve in ceremonies.
