What Signs Are Most Prone to Drug Addiction?

What signs in your experience are more prone to drug addiction?From what Ive seen your rarely ever see aries or leos addicts.Most people with drug or alcohol addiction are virgo,capricorn,taurus,pisces and scorpio,and cancer all the earth and water signs!
Im not trying to insult anyone,I agree most people that drink or do drugs are most likely depressed.
Im just saying from the people Ive met its mostly earth and water signs,I was just curious to see other peoples experiences.Honestly I know a lot of leos and none of them do crack or meth only couple smoke herb once in a while.
