I know that this question was asked of Australians butt I'll put in my Seppo 2 cents. A Junkie in the US typically is a heroin addict. dopefiend is interchangeable and the prefered term by some ( one could be an adrenalin junkie, ect...) Methamphetamine addicts are called "tweakers" and people that use coke "coke heads." Crack smokers are "base heads."
At any rate, speaking of heroin it seems to be more stigmatized than the US and Europe, while ice, is associated with "white trailer trash" or gays. Alrgough in Hawaii and parts of San Diego, everyone is smoking it. In the Brothels of TJ, the girl brings a loaded pipe up to the room- the major part of foreplay.
I get the impression that Ice enjoys fairly wide mainstream acceptance whilst it appears heroin is demonized. I also know that the rules of this forum discourage heroin related questions even general ones like is there a scene for it. Did Aus rebound from the 2000 drought? Is the heroin SE Asian #4 or smokable afphgani brown? What is the heroin scenes like in the different parts of Aus? Is there currently a drought? I know I can't ask these questions because I asked them before when I found out that Europe was having a severe heroin drought (there is a dedicated thread with quality, or lack there of, and prices of small amounts).
I'm not visiting aus soon unfortuanately but I wanted to compare and constrast the heroin availability and use trends in aus and Europe. But I don't want to break the rules so I won't ask the questions or expect posted results. Ya'll don't worry about the narcoswine getting intel on the scene- they have a sea of snitches to feed them that info (though they have been known to monitor BL). I don't expect a posted answer, but any vetran dope fiends please PM me time permiting of course.
I have a morbid curisosity of drug history and culture as Drug Mentor could probably attest to based on my posts in DiTM during his tenure there as a mod, many of which were historical articles or period pieces with contemporary articles thrown in.
These reason I'm confounded is because I see lots of info about Ice, LSD, ect... but nothing about heroin which leads me to think that it is demonized and considered extra taboo.
