If you were wondering: No, the marijuana industry hasn't lost its allure. Although the Horizons Marijuana Life Sciences ETF fell 36% in the past year, some pot stocks have reported impressive sales. With national elections on the horizon and marijuana legalization initiatives on the ballot in few U.S. states, investors are optimistic about the industry's room to grow. Medical cannabis is already legal across Canada, in 33 U.S. states, and the District of Columbia. The market should expand even more as marijuana-related therapies offer patients benefits that conventional therapies have failed to provide.
