Spencer Pratt – King of Weed?

When ‘The Hills’ bad-boy Spencer Pratt was just 15, some unkind friend introduced him to pot. And he’s been a big fan ever since.

According to sources, Spencer has wrestled addiction for several years, and despite long stints in rehab, still smokes to this day. So when he and new ‘wife,’ Heidi Montag, were spied at a medical marijuana facility last month, none of his friends were even remotely surprised. ‘He was the King of Weed!” says a friend. “He always had a big bag and would share with everyone.”

Once the pot worked its will, it was not quite enough, and Spencer’s tastes expanded to Xanax and Valium — even turning friends on to their dangerous thrills, “He gave me five pills and said I’d be OK,” says another friend. “I didn’t know it was too much. The next day he said, ‘Girl, I gave you so much, and you just handled!’”

To his credit, the Los Angeles native tried rehab again to break free of the pills – but was back smoking weed in less than six months, “He walked into a party, pulled out some pot and said, ”We are soooooo getting stoned!’ a close friend told The Star. “No-one thought much of it, because at least he was staying away from the pills.”

Spencer, 25, was even mugged recently, but too high to fight back because of the pills. With that pain in his past, plus a wife, plus ‘The Hills’ tanking ratings, the poor guy needs to get clean for good.
