Banks typically won't process credit transactions for dispensaries, so most are a cash-only business. That means your store may need the same level of security as your average casino. Denver Relief's 1,000-square-foot storefront features 16 IP-based cameras connected to a DVR, bullet-resistant windows, steel doors, alarms, and a Kevlar-lined wall between the lobby and the back office. By law, dispensaries in Colorado are also required to have a sturdy 1000-pound safe like the $4,000 American Security model pictured here (but skip the guns, or you'll violate federal laws). The good news: Insurance is relatively easy to come by, so you can lose your stash and your cash and still stay in business.
