I was wondering if anyone had ever tried iv cyclizine, diphenhydramine, hydroxizine or something else intravenously with heroin or some other opiate. And I also wanted to ask, how long does heroin stay heroin in a solution? I want to micron 4 or 5 shots for a special occasion and I don't want it waste micron filters, they are Whilst not expensive, still a hassle to buy. Apart from that they cost 2 bucks so... I get mine from a needle exchange BTW.
