Oregon state lawmakers who fear heightened marijuana enforcement by federal agents overwhelmingly approved a proposal to protect pot users from having their identities or cannabis-buying habits from being divulged by the shops that make buying pre-rolled joints and "magic" brownies as easy as grabbing a bottle of whiskey from the liquor store. The bipartisan proposal would protect pot consumers by abolishing a common business practice in this Pacific Northwest state where marijuana shops often keep a digital paper trail of their recreational pot customers' names, birthdates, addresses and other personal information.
