So I have a question I could really use help with, I’m not sure what to do.  I’m an IV drug user.  The other day I had someone over who was using drugs IV.  Later that day after the person left I had a needle on my table that had a bit of cooked/prepared heroin in it.   (It was pure dark brown in color no blood in the needle whatsoever.  I put them he didn’t rugs Into a fresh clean needle and injected it, thinking it wasn’t mine from before. I’m not concerned that maybe it was not mine and could have been leftover from my geust.  I put it into a fresh needle to use it but I’m still concerned that I think could potentially have been in a needle she used before.   I’m not sure what I should do and am very scared about the situation......please any help would be greatly appreciated. This all happened yersterday around 1:00 pm (July 23).  It isn’t not 10:23 July 24th as I write those post.
Thank you
Hi there,

Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission in the event that you had unintentionally shared a substance that was previously in a needle that may have been used. 

From the information given, this scenario is determined to be of High Risk (Transmission of HIV is possible in the given scenario). The scenario mentioned above does meet the three components of the transmission equation. It satisfies the transmission equation because there is a possible presence of HIV positive bodily fluid (in this case, blood), with direct access to the bloodstream, through 'needle sharing'. 

The scenario you have presented appears to deviate from 'typical' needle sharing practices, where an individual will use a needle, with a second individual following, using the same needle. However, the possible presence of blood within the substance, whether it was transferred from one hypodermic needle to an unused hypodermic needle, can present a High Risk
 of transmission.

This is because hypodermic needles may create a vacuum-sealed environment, keeping HIV positive particles intact. 

Due to our assessment, we recommend that you seek HIV screening from a healthcare provider. Further, we recommend that you also seek post-exposure prophylaxis (PEP), due to the High-Risk nature of your scenario.

PEP is generally recommended to those who have been exposed to HIV transmission within a 72 hour window period. We recognize that this scenario is time-sensitive, due to our currently scheduled hours we were unable to acknowledge your post in a timely manner. We understand that our recommendation is well beyond the required time-frame in which you would have received this time-sensitive information. 

Again, please seek HIV screening for the above scenario. 

Thank you kindly,
