Four men appeared at Bradford Crown Court and have been jailed for over 15 years roles for a conspiracy to supply class A drugs in the city.
Aqib Javed, 24, of Cecil Avenue, Great Horton, was jailed for four years and six months.
Khalid Hussain, 23, of Grisedale Close, Great Horton, was sentenced to four years and three months imprisonment, with a consecutive six months sentence after admitting dangerous driving.
Aqeel Zaman, 27, of Kirkham Road, Lidget Green, was imprisoned for four years.
Usman Chaudrey, 28, of Pickles Lane, Great Horton, was jailed for two years and eight months, with a further two months imprisonment for dangerous driving.
All four pleaded guilty to the drugs conspiracy charges.
Sentencing them at Bradford Crown Court, Judge David Hatton QC said: "Each of you has pleaded guilty to playing a part in a conspiracy whereby class A drugs were supplied to order by customers dialling a mobile phone number, which was placed from time to time in your mobile phones.
The supply of drugs went on for a period of weeks in 2015. The customer would be phoned back and his or her requirements speedily provided.
The judge said that each defendant played their part in the crime fully understanding what was going.
"Those who distribute these substances on the streets of this, and any other city, can expect to receive a sentence of imprisonment.”
