I have quit smoking weed and didn’t light any join for more than 3 years. I started, like everyone else in college with a bunch of friends. We used to share a joint between 3-5 people. Later, everyone started to roll their own joint. After a while, I couldn’t fall asleep without 2 joints. One of my friends persuaded me to take this simple test https://quitmarijuana.org/marijuana-addiction-test
I didn’t even realize that it is possible to become addicted to weed. But the big step was that I accepted the fact that I need help.
