Los Angeles: Charlize Theron says she and her mother use marijuana to combat their sleeping problems, and it is in fact her mom Gerda who gets it for her. She made the revelation during an appearance on 'Jimmy Kimmel Live!', reports people.com.'I'm always willing to try anything. You got one life to live, why not? I have really bad sleep (patterns) and so does my mom. We do take sleep medication and I was saying to her, 'Maybe we should try a sleeping strain, something that could help us with sleep',' Theron said. Theron said she never expected her mother to be the one to shop for it. 'I really thought I would be the responsible one to have to go and get that. Last week she showed up at my house, literally drove in her little tennis outfit and brought me a little container and just left it on my kitchen table. 'She was like, 'So I got some blueberry covered chocolate ones but if you want it faster acting you should go for the mints those you suck and it works faster.' I assumed because she was in a tennis outfit, she had scored with one young tennis friend. Because she plays tennis with these really cool young girls,' she said.
