US embraces marijuana as a mainstream business

Investors searching for the next big thing are increasingly being drawn to the US commercial marijuana business.

With more states voting to legalise the product, a once criminal activity is fast entering the mainstream with financial institutions, advertisers, and blue-chip investment firms waking up to the wider possibilities of this flourishing industry.

Medical and recreational marijuana is now legal in 24 US states, with a further nine due to vote on legalisation over the course of this year.
