AMSTERDAM -- Cannabis connoisseurs in their thousands have descended on the Dutch capital of Amsterdam this week to sample and select the winners of the 20th annual Cannabis Cup competition. "There's a lot of good competition this year," said 'Herbal Santa' a longtime marijuana smoker from Orange County, Calif., who only provided his name as Jim when asked. Organizers said they expected about 3,500 participants. The week-long Cannabis Cup is spread out at various coffee shops throughout Amsterdam, although the main events are held in a club on the outskirts of the city, tucked behind a McDonald's fast-food restaurant and a do-it-yourself store.
