I find it quite funny that myself, and most of my friends smoke weed. There have been numerous Friday nights where we have all sat around and had a smoke as opposed to going to the town centre and getting horrifically drunk. It really shows the difference in culture when, instead of someone's mum coming in the room to find everyone getting rowdy and drunk; they are sat there watching a documentary on the planet and having a chat.
Who would you rather encounter in the dead of night: A group of stoned youths or a group of drunken youths?
In all likelihood the stoners will avoid you, whilst the drunkards will actively seek a reaction in some way.
There is, of course, a culture of excess in England. However, excessive smoking simply leads to sleeping, so I fail to see the problem. Of course there is the schizophrenia debate, yet there are countless downsides to alcohol and excessive consumption.
It is all the media hype and political controversy which comes about with legalising or decriminalizing, not the straight scientific facts, otherwise we would all enjoy our Friday nights in a coffee shop!
Something does need to be done, though, as cuts keep getting smaller and smaller - And as I am merely an 18 year old who still lives with his parents, I am currently unable to harvest my own fruits of labour, and as such am a part of the criminal underworld! Hell, I work in M&S and half the bloody staff are!
