Foreward Over the last 30 years I have personally seen how drugs have affected individuals, families, and communities.Working the streets as an undercover Maryland State Police Narcotics Offi cer and then as a Carroll County Drug Investigator; I have worked closely with the school system, juvenile services, drug treatment court, diversion programs, such as Choices, Community Conference, Heroin Action Coalition and other support groups. This is where the author and our paths crossed.My first impression of Tim was of his sincerity of helping anyone involved with alcohol or drugs. He was a recovering addict with close to 5 years of clean time.He was literally on the street as a "junkie" but was able to rise above and mend his relationships with his family and be a successful member of society. He speaks of his life experiences in an attempt to keep other young people from walking in his shoes. His story is quite profoundand will give the reader an eye opening picture of what it is like to be addicted to drugs. It also gives hope that it is possible to make changes and turn your life around; he is a walking testament to that. It took years of livingon the street and several near death experiences; before he decides to do what he needs to do to break the chain of addiction.
