Shares in the two NZX-listed medicinal cannabis companies were sold down in volatile trading in the aftermath of the "no" vote in the recreational cannabis referendum, held in conjunction with the October 17 general election.
Both companies have stressed that their business models are in the medicinal cannabis area, not recreational.
By mid afternoon, Cannasouth, which listed in June last year, was trading at 72c, down 6c, after sinking as low as 61c.
At the same time, Rua, which listed last week, fell by 4c to 64c after sinking to 58c.
