Around here there is this type of heroin sold in clear capsules filled with off-white powder with some brown specs. I have only shot up about 5 times, but he noticed a few differences with these "caps". When dissolving the heroin in water, the shit smelled like peanut butter, but it all dissolved except the water had a slight brown tint. The rush was awesome after injecting, but within a few hours, I would feel like shit, his head would hurt, and him and his friends all had the shakes after sleeping for an hour, upon wakening gave very strange shakes. Anyways I want to know how to avoid this headache/nausea in the future without losing the entire amount trying to purify it with some acid/base technique. Could this heroin possibly be washed with Acetone or is it acetone soluble?
