Campbell has represented West Indies in 20 Tests, 6 ODIs and 2 T20Is.
As per a Reuters report, the 18-page decision by a three-member independent panel followed a charge of evading, refusing or failing to submit to sample collection.
Campbell represented West Indies in 20 Tests, 6 ODIs and 2 T20Is before JADCO accused him of refusing to provide a blood sample at his home in Kingston in April.
“The … panel is persuaded to a comfortable degree of satisfaction that the athlete committed an anti-doping rule violation, namely breach of JADCO rule 2.3. …," the decision read in part.
“The panel does not find, on the evidence presented, that the athlete’s anti-doping violation was not intentional.
“In the circumstances of this case the athlete is ineligible for a period of 4 years," it added, citing the applicable JADCO rule 10.3.1, with the ban backdated to start from notification of the violation on May 10 this year.
