uhh clearly misinformed. east coast heroin (specifically NJ) is the most pure according to the DEA and has been so for several years. the main port of entry for the entire country is the port of newark and thus reaches the hands of fiends with much less cut than is added through transportation. the type of heroin must also be distinguished (tar vs. #4 powder) because #4, typically not available on the west coast but recently showing up, is usually of a much higher purity. drug and vice unit have a compelling interest to make a claim - more fear = more money. i would do a bit of outside research beforehand. similarly - what would a local drug and vice unit have as a comparison? high overdose levels more likely point to a cut with a drug such as fentanyl (synthetic drug more cheaply produced than heroin) than a high level of purity. in addition, the only reason that NJ receives such high purity heroin is because of the fact that it is the entry port for most cartels. i highly doubt that portland is the main port of entry for the west coast - california has much more traffic in its ports and is easier to smuggle drugs into. looking at pure numbers, california has much higher amounts of the drug seized than oregon, close to 20x more. please don't take the word of people who have a personal interest in the matter at hand. do a bit of research and save yourself some embarassment.
