Ummm, maybe she was buying some as stocking stuffers??
While it's totes possible, it's also possible Mischa Barton was just accompanying her friend to the medical marijuana store as the two were spotted dropping by one in Silverlake this weekend.
The lovely ladiez were spotted heading into Crazy Grass Collective before they moved onto Ragg Mopp Vintage clothing store for some more typical purchases.
We're not sure Mischa partook in any Mary Jane activities, but it might not be a bad idea when dealing with all those crazy holiday shoppers! LOLz!
And if you find some green plant bits in your stocking this year, it's not pine needles from the Christmas tree!
Mischa Claus must have paid you a visit!
