Man, the only time I ever ate weed I was high for a loooooooooong time. I ate two pot cookies a friend gave me around lunch time. When my girlfriend came home around 6:30 that night she took one look at me and said "you're baked" . From what I remember I was still high when I went to bed that night. So, how do you get rid of a high from eating weed? You don't, you just wait it out and hope to hell you don't need to do anything that requires a clear head.
