Big Brother 9
On Big Brother, Jasinski was paired with Sheila Kennedy. Jasinski won part two of the three-part final "Head of Household" competition. At the finale, Jasinski became the winner of Big Brother 9 by a vote of 6-1, defeating fellow houseguest Ryan Quicksall and earning the $500,000 prize. Jasinski received votes from Matt McDonald, Chelsia Hart, James Zinkand, Natalie Cunial, Sharon Obermueller, and Sheila Kennedy. Jasinski only lost the vote of Joshuah Welch. He played a great game and said afterwards "only if they knew how easy it was to win it all! I would love to do it all over again and really share with the diary room and America my strategy. I was very skeptical therefore held back from everyone watching what I was truly up to!"
Jasinski was arrested on October 19, 2009, and was charged by the Drug Enforcement Administration (DEA), in North Reading, MA for possession of 2,000 oxycodone pills with intent to distribute. Jasinski admitted to funding his illegal venture with the $500,000 winnings from the show, and to buying and reselling oxycodone pills for several months. Jasinski faced a maximum of 20 years in prison and a $1 million fine.
Big Brother finalist Sheila Kennedy, who voted for Jasinski during the "jury house" portion of the show, stated she felt betrayed by him for using his prize money to fund a drug ring, as he had promised to donate $100,000 of it to an autism charity.
On October 4, 2010 Jasinski appeared in U.S. District Court in Boston, Massachusetts and pleaded guilty to charges of possession with intent to distribute Oxycodone and failure to file a tax return for the year he won the $500,000 prize on Big Brother. Jasinski was remanded to custody. In what has been described as an ironic twist, Jasinski’s lawyer said she planned to recommend a sentence of house arrest.
Adam Jasinski is now an addiction recovery consultant and professional interventionist in the fields of mental health and substance abuse. 
Jasinski released a book titled My Kid's On Drugs, Now What? which is a resource for parents on how to guide their child down the path of long-term sobriety after treatment.
