Acreage Holdings is an all-purpose marijuana company that handles operations such as cannabis cultivation, processing, and managing dispensaries.
Vahan Ajamian, an analyst at Beacon Securities Ltd., has indicated that Boehner's involvement in the cannabis industry may help "legitimize" the sector and generate investor interest, the Financial Post reported.
Boehner, 68, represented Southwest Ohio from 1990 to 2015.
It appears Boehner's views have taken a 180 degree turn since leaving office. Twenty additional states allow for some form of medical marijuana.
Acreage announced that former Massachusetts Gov. William Weld has also joined the firm's board.

"With the majority of Republicans favoring legalization and states rights, it is no surprise that mainstream right-leaning politicians are beginning to gravitate towards cannabis". "There are numerous other patient groups in America whose quality of life has been dramatically improved by the state-sanctioned use of medical cannabis". About 22 percent of veteran households said they use weed for medical reasons. Boehner specifically cited the potential of medical marijuana to help stave off the opioid epidemic as a rationale for his changed thinking.
