It stands to reason that the government would want it to stay illegal. If it becomes legal at the federal level, think of the implications. The govt knew about remedies this plant possesses and yet kept it from people. Lawsuits would follow. Unless there is perhaps a provision for them not to be. Aside from that, Cannabis legalization would thoroughly turn the economy upside down from what it is now..in my opinion. The paper industry would be effected along with the oil and gas industries. Govt don't want this as they would lose their fat paychecks.
