Listen to Gucci Mane on iHeartRadio

Gucci Mane is coming clean about his recent erratic behavior. 

Apart from lashing out on Twitter, the rapper was recently arrested for marijuana and gun possession in Atlanta. 

Over the weekend, Gucci took to Twitter, writing that he's "so embarrassed and ashamed" of his behavior.  He admitted that he's addicted to "lean," which is prescription strength cough syrup mixed with soda.  Gucci says he's been drinking "lean" - also known as "sizzurp" - for the past ten years and that his addiction has "destroyed" him. 

Gucci also apologized to his family, friends and fans, as well as rappers Drake, Rick Ross and Birdman.
