A Lansdale man has admitted his role in a cocaine ring that sold the drug throughout the borough. 23-year-old Eric Joseph of West Main Street pleaded guilty to possession with intent to deliver.  He was arrested about a year ago along with his roommate, 23-year-old James Clemons, who is awaiting trial.  He was given three to six years in state prison, but he could get out after two years and three months if he completes a boot camp program for drug-addicted offenders.
