Barry Ramsey was part of a gang of drug dealers to be among the first in the country convicted of supplying NPS – formerly known as legal highs.
A total of 12 people were sentenced at Newcastle Crown Court following a number of raids across Newcastle in March.
They had been targeting vulnerable people in the city centre and supplying them with New Psychoactive Substances (NPS) that left them in a zombified state.
Many of those taking the drugs were being targeted by the dealers and resorted to begging in the city centre to fund their addiction.
Northumbria Police launched an investigation into a number of suspects and used covert and undercover tactics to identify suppliers.
More than 200 grams of psychoactive substances were seized at just one address which had a street value of £2,000.
Each bag of product was branded with names such as Spice, Old Jamaican Extreme and Alabama Wildfire alongside the wording Not for human consumption.
Speaking after sentencing, Newcastle city centre Chief Inspector Dave Pickett praised his officers for being proactive in their use of the new legislation.
He said: “I just want to say that Newcastle isn’t alone in having an issue with NPS and the effects that then has on people in the city centre.
“As a force we have been very proactive in our approach whether that be through releasing videos of the effects on users or by executing warrants to disrupt dealers.
“The fact that this is one of the first cases to come to court under the new NPS legislation should be a real plus point and should reassure the public that we are doing everything we can to tackle the use of such substances.
“Our officers have used a range of tactics available to them and gathered a huge amount of evidence that left the defendants with little choice but to plead guilty.
“I am very happy that the judge has handed down custodial sentences and this should act as a real warning to those who are supplying NPS in our region.”
