Cannabis before and after prohibition
So in the 1850's - 1937 cannabis was an active ingredient in medicine. It was used for over 100's of separate illnesses and diseases according to the U.S. Pharmacopoeia. It was actually introduced by Dr, William Brooke O'Shaughnessy in 1839, it was introduced as cannabis indica or indian hemp. In 1851 marijuana is admitted and recognized as medicine in the 3rd edition of the U.S. Pharmacopoeia. It is worth noting that cannabis was removed from the U.S. Pharmacopoeia in 1942.
So what happened in 1937 to change the medicinal use. Well the Marijuana Tax Act happened the prohibition laws prohibits the production, importation,possession,use, and the dispersal of cannabis. So now Dr's who once prescribed the medicine containing cannabis now are prohibited from doing so. Although nothing physically changed the medicinal properties if the cannabis plant, perspectives had changed.
In 1970 the federal government put in place a Controlled substance Act of 1970, declaring cannabis a Schedule 1 drug. Making it no longer able to be used by medical professionals. Under the schedule 1 classification the Federal Government considers cannabis to have no medical or therapeutic properties. As I stated earlier no medicinal properties had physically occurred in the cannabis plant.
Today this plant is legal for medicinal use in certain states and even recreational in some as well. Fighting the stigma that was brought on by the prohibition still exist. Only in this day and age we can use all the scientific research, and education on the cannabis plant to counter the ignorance of not knowing the beneficial uses to this plant and really reach the schema.
