yes, that was exactly was i was thinking. only thing i'd probably always iv is heroin/hard opioids. because any other ROA is a complete waste.
edit: also benzodiazepine injection solutions. god i wish i could get my hands on on some midazolam solution. that, mixed with bupe, were probably the most incredible highs i've ever had.
<truthinfinitely superior high (theres a fairly niceeee rush).
