Recently acquired some Heroin (don't know what kind or it's strength), it's off white / light grey in color. Never used H before.
I have a light opiate tolerance (oxycodone 10-15mg to feel anything).
For ROA I tried smoking it in a glass meth pipe (ball and tube style), heat was applied to the glass and the H started to melt and bubble until it turned black.
I was able to inhale a bit of vapor/smoke , enough to get a short and sharp cough from it. But I didn't feel a thing afterwards, waited 10 minutes and still nothing.
I had placed 10-15mg approximately in the pipe.
Am I doing this wrong ? How come I don't feel anything from it ?
