Doctor Mensel, I commend you and on your life’s work of researching the disease of heroin addiction. I have been an opiate addict since the age of 22 and I am now 55. I can really relate to the concept of losing my free will. the horrible cycle of use, withdrawl and detox, is as chronic as the disease and also shaming. The whole drug rehab system we have in this country is set up to be failing and shaming. Today I am on methadone for my heroin addiction and I feel okay other than being chained to clinic every day of my life. A drug rehab that does not understand the need to be on an appropriate dose of methadone. I continue to use off and on. This is not what I want for my life. I have periods of being clean long enough to obtain a graduate degree in addiction counseling, get my credentials and begin my career only to use and end up without a job, suspended license, and more guilt and shame. When does the heroin addiction stop? so Please continue doing the work you are doing. We need you so much!
