Got a hold of some shitty dope

So you guys all know what it feels like to get a hold of some stuff that sucks but it will still get you well. I don't mind that. But I am stuck with this shit, it is some light brown colored stuff. Honestly in my opinion it is some really good dope that has a small amount of some cut in it but basically whatever is in it has ruined it. It burns like hell and fucks my nostrils up. It is dope and it keeps me well and even gets me high but I don't even want to do anymore of it.. I have a decent amount of it about 2 grams. So my question here is if I were to put some in a spoon and cook it up, filter it through a cotton, I would be way better off correct? I have a syringe and everything I need. I'm not very familiar with IV.. I have only ever had someone hit me I've never done it myself. But could someone give me some insight on this. By cooking it and filtering through a cotton, would I not be getting rid of whatever the cut is that's giving me issues? Obviously times are tough and I can't afford to take it as a loss. it is good dope it just has something in it that's no good. Thanks.
