Roughly two weeks before April 20, investors with a craving for marijuana exposure will have a new instrument with which to get it in their portfolios.

The first exchange-traded fund with a marijuana focus, the Horizons Medical Marijuana Life Sciences ETF, has been approved for listing by the Toronto Stock Exchange. It is scheduled to debut on April 5 under the ticker symbol HMMJ. According to Horizon ETF Management, it will be the first ETF “that offers direct exposure to North American-listed stocks that are involved with medical marijuana bioengineering and production.”
