The accused men are in their 25s, 40s and 30s, respectively.
A dozen buyers are also being prosecuted for buying cocaine.
According to the indictment, the sale was mainly made in a pub environment.
The younger men were arrested in Örebro on January 19 and have since been detained.
The two have been able to be linked to a sales phone and according to the prosecutor, the evidence is good.
- This is a case that is based on secret coercive measures in the form of telephone tapping and other things such as swish transfers and observations by the police.
Together with the police, I have selected the cases where we think there is sufficient evidence to bring charges, says Karolina Lindekrantz, prosecutor at the National Unit against International and Organized Crime.
Cocaine in the home
The third man, who is in his 40s, was arrested in January but then released.
He is still suspected of a serious drug crime, as the police found a large amount of cocaine in his home.
- As for the main defendants, they deny.
Then there are a number of buyers where some acknowledge and some deny.
It is the case that we have some of the buyers where there have been seizures in connection with scouts being on site in connection with the arrest, says Lindekrantz.
Nitrous oxide sales
The investigation has revealed that the men also sold nitrous oxide to young people, which is not illegal, but according to the police helps to finance serious organized crime and increases the risk of young people approaching drugs.
The trial starts on May 18 and is expected to last for ten days.
