My boyfriend is a 'recovering' heroin addict. He went to prison for a few months for a heroin related incident and was forced to get clean. He had been in and out of rehab before getting locked up with no success in kicking this addiction. Since being home from prison, he swears he will never use again. At first, I believed he was done. Recently though, I have noticed symptoms of drug use. While these symptoms are not near as apparent as before, I still believe he is doing something. His pupils are tiny, his face looks droopy and he has tons of energy. He walks, talks, and acts completely different. Is it possible to be using heroin and gain energy? I know that he is not shooting so I know the symptoms vary a bit. He swears up and down that he is not using but I have that gut feeling that he is lying. How do the symptoms of heroin use vary when its being snorted rather than shot up? One last thing, he constantly tells me to pick up a drug test because he will pass it everytime. Is there a way to pass these drug tests after using that I am not aware of?? So confused..irritated..etc.. Any suggestions as to what to do and knowledge of mental symptoms of use is greatly appreciated.
