So-called ganjapreneurs will be a prominent part of the 40th annual national conference of NORML, the largest public interest marijuana lobbying organization, which opens Wednesday in Denver, the Mile High City. The theme of the event is amp;ldquo;Coming of Age,amp;rdquo; a reflection of the status of cannabis commerce. Colorado has become the center of America's legalization fight, and we want to both encourage that movement and learn how we might more effectively export that fight to other states, said Allen St. Pierre, NORMLamp;rsquo;s executive director. Colorado passed its first medical marijuana law in 2000 and is now the nation's No. 2 market for legal marijuana, behind California. - NBC New April 20, 2011
