Risk of Prosecution for Marijuana-Related Companies.  If you are considering investing in a company that is connected to the marijuana industry, be aware that marijuana-related companies may be at risk of federal, and perhaps state, criminal prosecution.  The Department of Treasury recently issued guidance noting: “[T]he Controlled Substances Act (“CSA”) makes it illegal under federal law to manufacture, distribute, or dispense marijuana.  Many states impose and enforce similar prohibitions.  Notwithstanding the federal ban, as of the date of this guidance, 20 states and the District of Columbia have legalized certain marijuana-related activity.”
