Those that watched the reboot will note that Roseanne began abusing opioids near the end of the season due to an injury, while Dan sought to get her help by trying to raise money for surgery.
"They had her die of an opium-or a opioid overdose", Barr told YouTuber Brandon Straka about 40 minutes into the interview.
Barr called the decision "cynical and disgusting".
"Oh, yeah, I don't want to be around, because I, you know, I'll get drawn into a negative thing", she said.
Barr then added she was pretty unhappy with how the writers seemingly made a decision to take her out of the show.
Fans of Roseanne Barr, who are not thrilled about the new show, have taken to commenting on the post and letting their disapproval be heard.

Four of the reported cases where pins were found inside the strawberries came from the brands Berry Obsession and Berry Licious. Authorities are liasing with retailes to ensure all stock is removed from sale to prevent any further incidents.
Barr found her character's death to be disrespectful to those "who loved that family" in the original "Roseanne" show. "I was never going to have Roseanne die of an opioid overdose". "She should have died as a hero".
ABC Entertainment president Channing Dungey fired Barr for her malicious tweets suggesting that former Barack Obama adviser Valerie Jarrett is an ape. That's in stark contrast to what she tweeted in May.
"I feel that they all lost a really good friend". "Don't think I don't have spies". It's done, it's over, there's no fight left.
