absolutely. if you would take a person who hasnt smoked weed before (at least not often) and make em "be" in a coffeshop for an hour or so (without actually smoking) he/she is gonna notice the weed. the atmosphere in the shops are soaked in weed smell, what'd expect?
I booked a Mini-Cruise for later this year, gonna see the sights. I can't wait. Apparently they have a Cannabis Museum, the only one of its kind in the whole world!
