Tobacco
The first use of tobacco was recorded with the indigenous people of the New World. Firstly, it was used for pleasure, but not too long after that, tobacco was thought to have medicinal properties. From relieving colds and headaches to disinfecting and keeping fatigue and certain diseases at bay, smoking was believed to treat numerous health issues.
In fact, it was even used as an anesthetic. It was soon known as God’s remedy or holy herb. In India, for example, people believed that tobacco was super beneficial for teeth health; therefore, they used it as toothpaste. Luckily, now we know how harmful tobacco can be since it was even linked to several types of cancers and not only.
