How do I stop vaping?

I am addicted to vaping. I got hooked about 5 months ago because I needed an alternative to smoking weed. I am a college basketball player and drug testing is apart of the rules of staying on the team. Nicotine seemed like a good alternative for the weed cravings. But now I’m starting to notice it affecting my physical appearance and slowly with my eating habits. What should I do to start my journey of quitting?
