- Investors apparently have taken the big crowds outside marijuana retailers in Colorado as a harbinger of potential growth in the still-new industry after the state launched the first legal U.S. sale of recreational pot.
- Most of the companies that could benefit are very small, with MediSwipe (MWIP), which sells transaction processing systems to the medical industry, perhaps the most established; others include GreenGro Tech (OTCPK:GRNH), which sells growing systems and equipment popular with pot farmers; Medbox (MDBX), which makes storage and dispensing machines for controlled medicines; and GW Pharmaceuticals (NASDAQ:GWPH), which focuses on medicines derived from marijuana.
