Children's carer Luchia Price was cleared of being part of a drugs gang and said: "It has been hell."
The 25-year-old, of Bestwood Park, spoke after a unanimous jury verdict following a three-month trial at Nottingham Crown Court.
She felt "amazing and emotional" as the not guilty verdict was announced by the foreman of a jury made up of six women and six men. She was among four people who were cleared on Thursday, January 30.
Ms Price went on: "I have never sold drugs in my life. This case has turned my life upside down.
"It has been a nightmare - it has been hell".
"I was supervisor at a nursery for special needs children and they could not employ me, although they were brilliant and stuck by me. I hope to get back to working with them now."
She said that defence barrister Simon Eckersley sifted through pages of 14,734 evidence and added: "He found it there that I am innocent."
Five other people faced charges of conspiring to supply Class A drugs in Bestwood. One was found guilty and jurors were unable to agree on another defendant, who may now face a retrial.
Several people had already admitted their involvement at previous hearings and now face jail terms when they are sentenced later in the year.
She was supported by her dad, Terry Price, 65, who sat through every day of the trial.
Father-of-11 Mr Price said: "You need to be there for your children.
"I always told them that if they have done wrong, they should own up. Luchia did nothing wrong and this happened to her."
Another person cleared was Jay Papp, 33, a care worker who spent eight months in custody awaiting trial.
When granted bail, he was ordered to live in Leicestershire and was unable to visit his seven children over Christmas.
He said: "I missed birthdays and all sorts of family events.
"I lost my job and my life was on hold. Now I am hoping to get my job back.
"I am not guilty and the jury was unanimous in agreeing," added Mr Papp, who comes from Bulwell.
