First post so apologies in advance for any and all rule breaking. I was wondering if anyone can relate heroin potency to the type of high it produces? For instance, does a lower quality product give the user a more upbeat and energetic type of high while a more pure product causes a nodding sleepy high? I have noticed my highs while using heroin can vary greatly but I have been unable to pinpoint which type of product produces which type of high. I?m just looking for people?s input and experiences to help me predict in advance what to expect. Thank you.
