Time -- Medical marijuana is becoming big business — racking up sales totals that rival those for Viagra, according to a new report. The report, released by See Change LLC, a Colorado company that provides investment advice to businesses (See Change is selling an in-depth version of the report for $1,150), shows that medical marijuana sales have already reached $1.7 billion in states where it is legal — compared with annual Viagra sales of $1.9 billion.
