This is what you have in your hands, a scientific literary book that tells the stories of three things that have taken over most people's moods and they have become addicted to them. They consume them in the early morning, at noon, at noon, at sunset, in the evening, and in between all of these times. They consume them at home, at the workplace, at the café, at parties, on the train, on the plane, on the ship, coffee, and tea.
The pages of the book narrate the history of these substances, and when different nations became aware of them. They also narrate pictures of the struggle of some peoples to obtain them, and what some writers and poets took pains to sing of them, or to criticize them - each according to their view of them - and these pages will also lightly touch on the scientific aspect so as not to be burdensome for non-scientists, so they talk in passing about its various plants, their cultivation, their chemical composition, and the opinions of medical men in their relationship to health.
