After watching one of these episodes, I'm under the impression that it is safe to pursue marijuana in switzerland. Of these cities, which has the best? Lugano, Lucerne, maybe lauterbrunnen, Berne, zofingen, Basel, Zurich?
Uh, you might want to rethink this.
I just Googled marijuana Switzerland and lots of articles came up about it being decriminalized. This is one of them: http://www.huffingtonpost.com/2013/10/03/switzerland-decriminalizes-marijuanan4037400.html.
If you read it, you will find that it is still not legal and that if you are caught with a small enough amount, you will only have to pay a fine. Here are a couple of quotes:
"Anyone over the age of 18 caught with 10 grams or less of the drug will no longer have to make a court appearance and will not have offenses entered into their permanent record; instead, violators will have to pay a fine of 100 Swiss Francs (approximately $110), then be on their way."
"But "decriminalized" is not the same as "legal," as a Swiss Broadcasting Corporation report makes clear. Growing marijuana plants, imbibing the drug in any form and dealing it are still forbidden."
Google it yourself and see what you find.
