I grew up in Holland.
I never smoked Tobacco (unless it was rolled into a joint), but I have smoked weed. There are 3 shops within a 10 minute walk from my house where you can buy it. It is not much of a taboo, if at all. It is not something I normally do though. I just become drowsy which is not the greatest of highs. I really prefer not to smoke tabacco, or drink alcohol or smoke weed. Though if I had to pick one, it would probably be the latter.
