Will Cannabis be the saviour of the US?

Here’s my theory:
The United States is obviously going through an economic depression and needs help. I’ve noticed the increasing number of states legalizing medical marijuana. I feel that soon, medial marijuana will be legal throughout the US and eventually, the commercial cultivation and sale of cannabis. In fact, a bill has recently been proposed to California that would fully legalize this. AB390

With the legalization of this production and distribution, there is the opportunity for millions of jobs to be created. The US will have a brand new cash crop and a powerful export.

Is pot our ticket out of the economic crisis?
