While the Guam Visitors Bureau and certain businesses have urged caution with promoting a cannabis industry on Guam, pointing to significant projected economic losses, Cannabis Control Board Chairwoman Vanessa Williams told the Rotary Club of Guam last week that she hasn't seen data backing those claims. GVB and certain businesses have warned against marketing Guam as a cannabis destination, concerned that it would damage the tourism industry, and have proposed banning cannabis use, advertising and sales in "family friendly" Tumon. Tourism officials presented to the Rotary Club of Guam prior to Williams, noting their concerns with cannabis in Tumon and GVB's estimate that cannabis would result in a $579 million loss to Guam, with a net loss of $486 million, taking into consideration projected economic benefits from cannabis.
