The book and the movie are both garbage
Filled with lies and sensationalism.
TRUTH: At 16 I smoked marijuana almost every day, took LSD, used speed, smoked hashish on occasion. I even tried cocaine and angel dust. Today I am a well-adjusted husband and father of two adult children who don't even smoke. I told them about my past and was honest with them. I didn't lie. The truth about pot is it does seem to put a damper on your thinking abilities, but there are no lasting effects. As for ambition, I don't think I ever had much ambition other than to be a writer, so you couldn't say drugs messed up my life. I never became addicted to anything, not even alcohol.
Picking up GO ASK ALICE and trying to read it and take it seriously, I'm sorry. Pure fiction. Pure lies. Pure garbage.
