Although Psych0 has been off the Heroin
for a few years now, he used to score his Heroin in Rotterdam 2-3 times a week.
Rotterdam has the largest shipping port in the world and has been for a century, if not longer, and partly due to this it has become the largest distribution hub for Heroin in Europe and probaply even the Western-hemisphere, with vast quantities coming in from Afghanistan/Pakistan before re-shipping to harbours across Europe and all along the Atlantic.
With such a large and steady supply of pure, uncut Heroin, it's no surprise Rotterdam is the Heroin capital of Europe and known for having the purest H in the EU.
Even though Rotterdam has the purest and cheapest Heroin, it's still of fair to good qualities in other cities across the Netherlands as well, though the closer to the source (Rotterdam) or to one of the major cities (Rotterdam, Amsterdam & the Hague), the purer and cheaper H you'll find.
Partly because of it's very high purity and low price and partly because the H here is #3 Heroin (the freebase), by far the largest majority (90-95%) of the users smoke it on foil although in the largest cities you'll find the highest pertentages of IV users with users in smaller cities all smoking it instead.
Among Dutch society, the police and even other drug
users, Heroin is very much frowned upon and seen as a loser junky drug.
Fortunately the police knows from many years of experience that taking a hard stand against Heroin will not work, and although our very liberal drug and harm reduction
policy has steadily been broken down by the Christian and right wing parties that came to power a few years ago, the police generally ignores the goverments proposed "tough on crime" attitude as regards to drugs
Fresh syringes, needles and other injection supplies can be gotten for free at the mental health clinics that can be found in every major city and who also supply Methadone
maintenance treatment or other rehab/detox programs.
Fortunately we don't have any "paraphernelia laws" in the Netherlands, and have decriminalised posession of personal usage amounts.
The police does not actively arrest drug users and in the major cities they usually ignore small time dealers as well and instead focus on major crimes.
There is a relatively small percentage of Heroin users in the Netherlands compared to other countries in Europe or the West, and as mentioned earlier it's very impopular among youths and rather a drug used by 30-40+ year olds.
Also, there's no recreative pharmaceutical opiod usage in the Netherlands as far as anyone knows off, with all the opioids
that are used being H & Methadone.
Other than Morphine
no one has ever heard of any other opioids and even among long term drug users they are unknown, largely because of the very pure and cheap Heroin that's available and the very tight regulations on controlled pharmaceutical opioids.
