What Is He On?

My boyfriend of about 6 months now has been hiding his use from me for a while now and I am trying to figure out what he is using. He tells me that he drinks and does blow, but i have been finding burnt spoons with white residue, baking soda, and today i found a bottle that said crystal girl on the outside. I know that he has been hiding a bong that he does not smoke weed out of. does anyone know what he could be doing? i am worried about him and i dont know what to do.
Crack Cocaine - Cocaine hydrochloride is mixed with ammonia or sodium bicarbonate (baking soda) and other ingredients, causing it to solidify into pellets or "rocks". The crack is then smoked in glass pipes. That answers part of your question.

The sppon could mean he is injecting cocaine, or something else.. but if coke is his drug of choice thats probably it.
I have a similar question. My husband has used different things often it seems he switches to something else when I have caught on to something. The last time that I know he used was last July--I found a piece of aluminum foil with some dark residue on it--I am thinking it was where meth had been heated and inhaled??? But then after that I found a makeshift glass pipe with some of his things and I could have sworn that I saw him in his truck with one this morning but he denies it. Would that be meth too? Was I seeing things or is it rearing its ugly head again.
That would be meth .... it can be smoked off of foil, or in a glass pipe .
I just saw in another message board that a wife had found tin foil and then she said her husband's drug of choice was heroin--how is tin foil used with that? I guess any drug can be used any way if they set their mind to it???
