Likewise on the Central Coast of NSW. Strong, white, either powder of rock, both mix up clear. Though the powder has a yellow tinge to it - and both smell of acetic anhydride (that vinegar smell), though not strongly. I overdosed on .25g of the rock which is my usual dose and had no other opiates nor benzos in my system. As always be careful kids. When it comes to heroin there's fine line between pleasure and death, and some of of us like sitting on the fence between the two, on the nod, not carrying or even obvious as to which side we may fall. Sorry to ramble.
Ash.
