KANYE'S GAS AT

Celeb dentist blamed for nitrous oxide habit.

GASBAG Kanye West's insane outbursts may be a result of an addiction to nitrous oxide, his former chief of staff claims! Now the ex-employee, Milo Yiannopoulos, wants to hold the celebrity dentist who supplied the 47-year-old rapper with the anesthetic drug also known as laughing gas responsible.

In an affidavit filed in conjunction with a complaint against Dr. Thomas P. Connelly to the California Dental Board, Yiannopoulos claims the DDS charged West approximately $50,000 a month to provide him with nitrous - which is widely used in dental procedures delivering up to four surgical-sized cans at a time to Ye's home.

In the damning declaration, Yiannopoulos, a rightwing activist who left the Grammy winner's employ in May, claims the pipeline kept flowing even after "the emergence of distressing symptoms" and signs the rapper was horribly abusing the drug.
