My spouse had a cocaine addiction in the past, before we got together. It was his drug of choice. Someone told me that he was using again. I have noticed things lately that make me suspect that just may be the case. What signs should I be looking for? I have never taken drugs in my life so I have no idea. I just know that he goes through a lot of money is a short period of time and lies about it when I ask what he spent his money on. I know when he is lying but yet he thinks I am too stupid to know that he is lying.
