Injecting - First Question

[stephy171072]

Hi there this is my first post I have come on this site for a little read a few times but I need a bit of help with something now and was wondering if anyone could advise me? Long story short I am not in the city where I live and there is no way for me to buy any heroin until tomorrow and I am really sick. I have a Martell bottle/crack pipe that I have been smoking the heroin through, when I scrape the pipe I can get quite a bit of brown remains out of it I am wondering if it is possible to cook this up to fix? Im thinking that it would be safe as the filter would take out anything that would harm me but there are some tiny bits of glass in the powder so that makes me a little wary. Any advise anyone could give me would be really appreciated because im really feeling bad now. Thank you in advance
