No illegal stuff, Dave.
I had one siff of an Afghan while I was already drunk when I was 18 and I didn't noticed a thing, since it wasn't such a big deal that was the last time I did illegal drugs. By illegal drugs I mean the same stuff as you are referring to: coke, speed, hash, XTC, crack and yes Dutch Nederweed, although the best in the world it's still illegal.
Dutch cigars are very famous for there various blends of tobacco from all over the world. When you ever get lost in Amsterdam I must recommend a visit to the cigar shop of Hajenius.
www.hajenius.com There cigarsmoking can be wittnessed as an art instead of a lifestylehype. However, avisit to any well stocked shop for cigarettes and cigars can be good fun, last cigars I bought where already dipped in Cognac, very nice!
