thanks so much. I appreciate your response.
In your question itself, you provide a clear analysis of why you could not have caught HIV. I agree with your reasoning. For what it is worth, I am unaware of any reported occurrence of HIV transmission by sharing cocaine snorting equipment. If it occurs, it is too rare to worry about. And from your description, it sounds like that didn't happen anyway (but of course only you can judge that; there is no way I can tell). And HIV isn't transmitted sexually through clothing. And HIV is rare among heterosexual women in the US and most industrialized countries.
So my conclusion is that there was no HIV risk. You have no cause for worry and do not need HIV testing.
I see this is your second low- to zero-risk, anxiety-driven question on this forum in the past 4 months. Please note the MedHelp rule about a maximum of 2 questions every 6 months on the moderated forums (see Terms and Conditions).
