I was in Amsterdam yesterday and was told the gist of this by a well informed source. Everything he said is as described in the extract below, taken today from the Netherlands Government's website.
My source also said, but this is not confirmed, that an individual would only be able to register with a single coffee shop, preventing both socialising, and the ability to exercise choice as to where you would like to smoke at any given time of day.
A few years ago, they stopped you being able to buy alcohol in a coffee shop, which also prevented mixed groups of people who wanted to both drink and smoke from socialising in the same place.
My source also asserted that the new measures would push drugs back onto the streets, where sales would be uncontrolled, organized by local criminal gangs with power struggles likely to cause injury and even death.
Not everyone who visits Amsterdam and other Dutch cities goes there to smoke. It's a wonderful place that you can enjoy in so many different ways. But all visitors will be effected by this, since the safe streets and canals that they enjoy walking along late into the night will not feel or be so safe any more.
I've been visiting The Netherlands for over forty years and I've always loved the people and the country for their practical, pragmatic, and progressive attitude to life. I'm saddened by this move, but I hope that sense will prevail. Please support the opposition to these changes. If I find a focal point for that, I will append it here.
There's some good, independent commentary here:
