Haha, this conversation sounds more like somebody felt uncomfortable in germany for some personal reason and it is a discussion in a very stereotype manner. Its like an European would write about the American that they only eat hamburger, watch Oprah Winfrey and love weapons...
German law is very flexible, its about in which federal state they fucked. Every federal state have there own definitions about whats for youre own consum or comercial drug selling, and very important that you dont have to cooperate with the police.
But when you fucked up you have a very big problem with youre driving licence. You lose it for ca. one year, you have to do psychological test and you have to go to seminars which prepares you for those test and you have to pay it all, thats very expencive and whith out a driving licence youre realy fucked up. I dont know about drugs&driving licence in other country, i think it always bad when they got you...
We have a hugh psychedelic scene in germany and nice psytrance partys
When youre carefull and play with the rules youre quite save. The cannabis stuff is very dangerous here, most people i know who have trouble with the law where caught with cannabis, i avoid cannabis
