Hemp

As useful yesterday, so persecuted today.
Until the decade of the 30s (in the twentieth century), the cultivation of hemp for its fiber procurement, was widespread. His fiber is used for both networks, clothes, tarpaulins, sails (sails of Christopher Columbus, the American flag and the papers in which it declared its independence were made with fiber Cannabis.). Perhaps the appearance of oil synthetic fibers, this plant began to be persecuted.
The medicinal use of cannabis is legal in a limited number of territories worldwide, including Canada, Germany, Argentina, Austria, Holland, Spain, Israel, Finland and Portugal. In the U.S., fourteen states have recognized medical marijuana: Alaska, California, Colorado, Hawaii, Illinois, Maine, Michigan, Montana, Nevada, New Mexico, Oregon, Rhode Island, Vermont and Washington.
In this article, I do not pretend that all of you smoke marijuana, but merely stated that the use of fibers should be returned to trade on the rise, and dispose of items affordable for everyone.
