He pleaded guilty to the offence on Monday.
During a raid of his home in February 2020, officers seized a large quantity of white powder, which tests showed to be more than 500g of cocaine.
Detective Constable Sian Cook: “The misery drugs can cause is well known not just to those who take them but to those in the local community as well.
"We will proactively target people we believe to be involved in drugs and use the powers we have to make sure their activity is disrupted.
“I hope Henderson’s sentence acts as a deterrent to others and goes some way to reassuring the public we will thoroughly investigate all drugs activity so we can bring offenders to justice and continue to protect our communities from harm.”
