I've never encountered meth in the UK, although I do remember seeing a couple of documentaries about 5 years ago, warning that a meth epidemic was imminent. It never seemed to happen (yet) though.
I have only deliberately taken meth once - it was during my first week in Australia, in early-2006. Me and a few friends had been to a dance festival, and then went back to my hotel room to smoke some weed. Unbeknown to me, a friend of a friend brought with him not only weed, but also a crackpipe and some ice! None of us (except the guy who owned the crackpipe and the ice) had ever even seen a crackpipe before, but it got offered around, and we all had a few hits. I probably had 4 or 5 hits. All it did was keep me awake for the next 2 days straight, and make my jaw completely lock shut - like a far more extreme version of the jaw-clenching you get from pills. I came to the conclusion that it was a pretty horrible drug - its just not the high I'm looking for at all.
I actually got to be friends with the guy who's crackpipe/ice it was, and he offered me it on a few occasions since then, but I always declined. As things stand, the only drug I've ever had a problem with is cigarettes, and I wish to god I had never smoked for the first time. I would hate to look back in a few years time and think 'I wish I'd never taken meth for the 2nd/3rd/4th time etc'. I've done it once, and have no desire to do it again. I did, however, smoke speed on a few occasions after that, and from what I have read on Bluelight, there's every chance it was actually just watered-down meth

But I certainly never had a meth high as strong as when I smoked it deliberately.
I have a theory about why meth has taken off in Australia (but not in the UK). I think it's because pills are so expensive in Australia, so it makes economic sense for clubbers to use meth, whereas in the UK, people are quite happy to munch through 10 pills in a night. I think this problem has been exacerbated by the poor quality of pills in Australia in recent years, whereas (correct me if I'm wrong) you can still get relatively good quality meth.
Another possible reason why meth has taken off in Australia (but not in the UK) is that there is no crack in Australia, whereas there's loads in the UK. At the end of the day, in poor neighbourhoods with high-unemployment, youre always gonna get problems with drugs, whatever those drugs may be.
I actually just watched the Louie Theroux documentary - I found it interesting, as I do all his documentaries. The only disappointing thing (and I find this about most of his documentaries) is that he never comes to any conclusion, nor does he suggest any possible solution to the problem. I'd say the same thing about Ross Kemp's documentaries - I'd love to hear his personal views about the issues he documents - e.g. how to solve gang crime. Surely you'd think that documentary makers like Louis Theroux and Ross Kemp would be in a better position than most to suggest solutions to the problems they spend months filming?
Anyway, for all you Europeans who have never tried meth - you're really not missing out. Unless, of course, you want to stay awake for days on end, and have severe jaw-clenching.
Peace out.
