'Full House' star kept nose full of coke on college tour

“Full House” star Jodie Sweetin was high on cocaine, even while telling students at universities across the country that she had kicked her habit once and for all.

The one-time child actor comes clean in her new autobiography, “unSweetined,” recounting nights of endless partying and drugs, including coke, methamphetamine and Ecstasy, even when she was supposedly sober, according to an excerpt at Amazon.com.

“I did a few key bumps and headed to the lecture hall, where a sold-out crowd waited to hear me speak,” Sweetin wrote. “I thought for sure that one of the professors would take one look at me and kick me out. But none did. They wanted to hear about the trials and tribulations of Jodie Sweetin, or at least the Jodie Sweetin I had created.”

Sweetin, 27, used the money from her appearances to pay for her $700-a-week habit.
