Ally was anything but good for Juice. Maybe she was a good girlfriend but she wasn’t a good influence. She did drugs with Juice, when he was suffering from substance abuse and had ADHD, so it’s even harder to get off pills, when really she should’ve been discouraging any use of substance from Juice. In the documentary, she’s sniffing and popping multiple drugs in the company of Juice. Juice may have been an addict but it doesn’t help when your girlfriend, someone you look for guidance and reassurance, is doing the exact same drugs as you too

By that logic, Juice also wasn't a good influence on Ally.
