geez, you people are spewing forth all sorta of missleading information. (which is ok, everyone makes mistakes)
I'll try to clear up somethings.
GOTHS: Ok, first of all, in the late Middle Ages, there was a group of Germanic tribes from Eastern Europe called the Visigoths and Ostrogoths. They roamed Europe and invaded the Western part form around 371-568 A.D. Other ones you may have heard of are the Huns, the Lombards, Angles/Saxons, Franks, Vandals (whom you may recognize from the band, as well as the word in the Engilsh laguage)among others.
Now, Goths refering to the social group. Goths are a new form of social misfits, characterized by a certain form of dress which is various and not specific, but is almost always in some sorta black. They listen to a form of death metal mucis which itself has been labeled as "goth." they also draw influence from Gothic literature, of which the most famous whould have to be Edgar Allen Poe. There have been many of these groups in society, from beatnicks to hippies, from punkers to surfers.
So As for as I know, GOTHS ARE NOT A GANG.
Now, as for gangs, I live in Brooklyn, NY, and you might expect there to be gangs here. Well, there are. Of course there are the Bloods and the Crips, who are spread nationwide. There are local gangs here in my neighborhood: the Hellraisers, the Dukes, the UFOs, and the Incas. There other gangs in other parts of Brooklyn, and more in other boroughs. And there is graffiti everywhere, even in the "good" parts of the city. But there are beautiful murals.
And as of right now in the US, Cannabis is only legal as a prescribed drug, I think. However, it is illegal any other way. It is still sold, smoked, used. Its almost as common as underaged smoking(cigaretts) and drinking.
