Cannabis is freely available in the Netherlands for sale in "coffee shops" in small quantities. The cost of five grammes, the maximum amount that can be legally purchased, is about £.50 ($19), enough to make about a dozen cigarettes.
The cannabis sold comes in vastly different strengths
There is a wide variety of cannabis available in the "coffee shops". A number of them have a "menu" where you can choose the type of cannabis by strength and cost.
