Talking to Bustle, Noah explained why he made that decision.
"Previous to [my 21st birthday], I was partying, experimenting, and just completely being reckless and being loose — while still managing a career," he said. "I was running on fumes, and I was pretty much getting high off the fumes that I was running on."
Noah realised that he was making poor decisions, especially when he "was on some sort of substance".
"I woke up the day before I turned 21 and was like, ‘Society is telling me I can legally drink now. … Funny, I’ve been doing that and way worse for the past three, four years," he explained.
Noah, who is now 22, is no longer sober... but his year long sobriety was "an act of self-love" and changed who he is today.
"I learned the importance of taking care of myself, [of] making myself mentally, emotionally, spiritually and physically sound," he said. "One always ties in with the next."
