The Opportunity Zone program is intended to stimulate positive growth within designated communities, as such there are restrictions on the types of investments in which an Opportunity Fund can invest. These investments are called “Qualified Opportunity Zone property,” which is defined as any one of the following: partnership interests in businesses that operate in a qualified Opportunity Zone; stock ownership in businesses that conduct most or all of their operations within a qualified Opportunity Zone; property such as real estate located within a qualified Opportunity Zone. So in essence, while cannabis may be illegal federally, you are purchasing stock/partnership in a business that operates in an OZ, that is legal. The IRS has yet to address this issue and it may provide on guidance as to what kind of business investment will be allowed, but as it stands now, you are permitted to invest.
