WHEN A YOUNG DRUG USER, WHO WANTED TO CHANGE HIS LIFE, BUT ON THE VERGE HE DISCOVERED HIS DESTINY

I can’t tell what the story is about from reading the logline.

A: Young drug user: This is the clearest part of the logline.

B: Wanted to change his life: So we have some backstory, at some point in the past the, lead character, wanted to change his life. But what does he want to do now? What is his goal today?

C: On the verge, he discovered his destiny: This sounds like the inciting incident. That means the story is what happens after he discovers his destiny. Your logline seems to be all backstory and no forward story. Also, we don’t know from the logline what his destiny is. (So we, the reader, will have to guess)

Example:
—–
When he discovers his destiny is to become a race car driver, a young drug user, (Must do this if he is to succeed)
—–
Since I have no idea what the lead character’s destiny is from reading your logline, I had to take a guess.

Since you seem to have a story that you are compelled by, it is just a matter of adding a little clarity to the logline so we the reader can get a glimpse of the story that is in your vision.
