First of all, everyone knows that speed is filthy - it is a drug that know its place. Most people who use it do so when they're young and give up on it. Those who continue do it for long social functions, long flights - it serves a useful social purpose (insofar as the majority of people yack endlessly about shit - with the speed user they just compress that a little). Those who use it habitually were always going to be wrecks. No sane person wants to be awake forever. If you do, you're not sane - speed is the drug for you.

Weed is 'cool'. It relaxes you. It makes you talk shit very, very slowly. It encourages you to listen to very, very bad music. It has psychological repurcussions in a great many people. Lots and lots of people do it.
Plenty of those people are deluded into thinking it's harmless. Many of them argue that cigarettes and alcohol are more harmful. Why yes, yes they are. That doesn't mean weed doesn't, or won't make you an idiot. Weed smokers, the sort getting towards their early-30s, are a load of sanctimonious pricks. There is no cut-off point with weed, because it is no-where near as ridiculous as speed. Because it's not ridiculous (i.e., you can just about saunter along at half-consciousness for months, years at a time) you never get the blessed relief, as with speed, when you finally stop doing it, if indeed you do.

These are irrational arguments, yes. However, in my personal observations - and if yours are different, I'd probably call you a liar - I know loads and loads of perfectly decent, intelligent people who habitually, or casually, smoke weed and fail to notice that (with a pitifully few exceptions) they become lethargic, anti-social lepers with faint notions of the intelligence they haven't excersized for years. With speed you either do it for a bit and realise why it's not a good idea or you're mental, in which case, you're mental so whatever you take isn't going to make a great deal of difference. It's more divisive, yes. And that's a very good thing indeed.

I could summarise with the following: people on speed listen to gabba, Happy Hardcore and your various tribes of hip-hop. People on weed listen to Pink fucking Floyd.
