Selena Gomez smoked pot with Justin Bieber when they were together. And then...

Justin = J = Jesus =  heart chakra = the color green = green leaf. After they broke up, she checked into rehab, supposedly for lupus, though.

Her next guy’s name was Abel = A = Alcohol, and his nickname is “the weekend”, as in weekend drinking binges. She moved down from the color/frequency of green to yellow/orange with alcohol now as her drug of choice. Alcohol is yellow/orange in frequency and represents being more emotional, animalistic, sexual, etc.

Who knows (or cares) where she'll end up next?
