Most parents try to dissuade their kids from doing drugs. RDJ's dad gave him his first joint when he was 6 years old. "There was always a lot of pot and coke around," Robert told People. "When my dad and I would do drugs together, it was like him trying to express his love for me in the only way he knew how." As he got older, RDJ would "spend every night out getting drunk...making a thousand phone calls in pursuit of drugs," he said. His using ended his seven-year relationship with Sarah Jessica Parker, which started when RDJ was a teenager. And while he didn't get arrested while he was underage, he spent time in prison in 1997 and 1999 for drug-related incidents.
