Why does Marijuana have such a negative connotation in the first place?

Well there are many causes to its bad reputation and a lot of it is based around propaganda and corporal greed.  Back when President Nixon of America came to power, his campaign was heavily based upon the fact that he wanted to keep Marijuana illegal. Once he was elected president he began to promote commercials stating that Marijuana has properties which cause cancer, and that Marijuana causes communism. However the majority of his information was invalid and he had no solid proof or evidence to back up his statements. You must remember though that this is mid 1900’s where technology was limited. At the same time though I doubt Nixon had any intention of looking into the matter. Back in the early 1900’s and several decades before that, the #1 industry in America was lumbering but was threatened by the rising hemp industry.  This was crucial reason for Nixon’s ruthless campaign against Cannabis and thus the negative view on the topic was formed.
