History of Marihuana Use: Medical and Intoxicant

From: Marihuana, A Signal of Misunderstanding, the Report of the US National Commission on Marihuana and Drug Abuse, 1972


The term "marihuana" is a word with indistinct origins. Some believe it is derived from the Mexican words for "Mary Jane"; others hold that "marihuana" comes from. the Portuguese word marigu-ano which means "intoxicant" (Geller and Boas, 1969: 14). This chapter outlines the many and varied uses of marihuana through history, and deals with its use in medicine and its use as an intoxicant.

The experience of the 1960's might lead one to surmise that marihuana use spreads explosively. The chronicle of its 3,000 year history, however, shows that this "explosion" has been characteristic only of the contemporary scene. The plant has been grown for fiber and as a source of medicine for several thousand years, but until 500 A.D. its use as a mind-altering drug was almost solely confined in India. The drug and its uses reached the Middle and Near East during the next several centuries, and then moved across North Africa, appeared in Latin America and the Caribbean, and finally entered the United States in the early decades of this century (Snyder, 1970: 129).

Meanwhile it had been introduced into European medicine shortly after the invasion of Egypt by Napoleon and had a minor vogue as an intoxicant for a time in France.

Regardless of which parts of the world are discussed, many of the same problems and concerns about cannabis are common to all, including the United States. Understanding its various uses during many centuries in diverse countries and continents can perhaps lead to a better understanding of marihuana in general.
