When explorers discovered America they also discovered tobacco. The indians thought that tobacco was healthy, so when explorers met the indians and the indians introduced them to this addictive drug explorers were told that tobacco was healthy.
The explorers who discovered America took the tobacco and brought it to Europe. They introduced many citizens to tobacco. When they introduced the plant they told villagers, and other citizens that it was healthy just like the indians told them.
The people in Europe consumed this drug in many ways. Some smoked it in pipes, cigars, or cigarettes. Others ate it straight up. Either way it was still a) addictive and b) unhealthy
