All methadone users use it because it is a free fix. Im my younger days I was around these type and they laughed about the feebee the gov gave them. When they wanted the real h they just laid off the methadone then got buzzed then went right back to the meth.
I say cut em all off and throw em in jail if the steal to support their habit. Lock em up and let em jones for a year or two. JMHO
