The statistics follow the news this week that a 12-year-old boy was pricked while playing on his school field at Grainville two weeks ago and now faces an agonising six-month wait to see if he has contracted HIV.
Of the 62 collections since 2004, five have been from schools which the police declined to name.
They said they did not have a record of the total number of needles found but did say that number was far greater than 62.
Police were called to Grainville the day after the boy was taken to hospital.
A further two needles had been found in the same area.
The boy is being tested for hepatitis B and hepatitis C as well as HIV and is taking 12 tablets a day and having one jab a week.
Alcohol and Drugs Services charge nurse Pat Devine said most addicts use drugs at home and the clinic offer safe disposal of their used needles.
