"The men who create power make an indispensable contribution to the Nation's greatness, but the men who question power make a contribution just as indispensable, especially when that questioning is disinterested, for they determine whether we use power or power uses us." These words of President John F. Kennedy one month before he was assassinated echo our present circumstances regarding cannabis prohibition. This year marks the fiftieth anniversary of his death; it is fitting that this year, 2013, also record the beginning of a united campaign to end cannabis prohibition with a United States Constitutional Amendment, a "Cannabis Freedom Amendment." This book is a resource of information about cannabis; it's history and benefits to humanity, its uses and potential uses, its potential economic value worldwide, and the devastating effects that cannabis prohibition has had on lives of millions of people. Few know that cannabis is proven to cure cancer; it's time that everyone knew this and had options regarding its medicinal applications.
