If cocaine was cheaper then it would be looked at more like meth. The thing is, when you combine cheap, free access to powerful neurotoxic stimulants with an addictive personality, the result is usually total decompensation. Stimulants can ruin someone's physical health sooner than any other drug class.
I was under the impression that cocaine isn't neurotoxic. On the other hand, I was likewise under the impression that there's also a significant difference between the rate at which cocaine will ruin someone's physical health (aka, way fucking faster, due to the much greater cardiotoxicity) than meth will, assuming equivalent amount of time spent under the influence of the drug.
Not to mention the huge difference in duration. It's much harder to casually use a drug that requires an 8 - 12 hour commitment.
Then there's the socioeconomic and historical aspect. I'm not going to sit here and break it down, because it should be fairly obvious to anyone who does some reading on the history of the meth and coke trades, but the reason they're looked on differently has a lot to do with how they entered into society and the view of the mainstream.
This has probably already been mentioned, but meth is quite expensive here in Australia, by American standards, and cocaine is even more so, to the point where meth is more of a middle class drug, simply because the rural poor ''white trash'' stereotype couldn't afford it, generally speaking. It has essentially replaced cocaine as the party stimulant of choice, although like cocaine in America, it also has a large scene of addicts, the difference being that smoking meth here is much more normalized and is not uncommon even among more recreational/party type settings, there's no huge gap in perception between eating it, snorting it* and smoking it, there is, however, a large stigma surrounding IV use. My understanding is that it used to be mostly local product, cooked by bikies, with a smaller portion of import, whereas there was a shift large shift in the early 00's when the ''ice epidemic'' took off and meth replaced heroin as the hard drug of choice (heroin having gone into drought around the turn of the century - my guess would be that this was all intentional, yaba taking off in SEAsia and someone catching onto the fact that meth doesn't rely on crop cycles), and then another shift in that ratio, around 2009 or 2010 iirc, which resulted in a temporary flood of high grade product being sold for double the price (if I had to take a guess, this would be when the SEAsia market hit capacity, so they started sending the overflow down here). Of course the high price stayed, the high quality didn't, although generally speaking my understanding is that there's still plenty of good stuff out there, just a ''who you know'' situation.
Cocaine, on the other hand, is so expensive that it's less of a recreational drug and more of a luxury item. The price is so absurd that there's just no justification unless you're quite wealthy, having it as an occasional treat or, generally speaking, trying to show off. Frequent trips to the bathroom and white residue under the nostril is a status symbol in what passes for high society (heh) in Sydney.
Anyway, I'm rambling. TLDR: Meth is our coke. Coke is our coke for wankers with more money than sense.
*Snorting, for some strange reason, is very uncommon. Those who don't IV tend to either eat it for a longer lasting, more physical high (passing around a bag of cheap cut 'speed' at a festival for everyone to dip their finger in, or pouring some into a drink), especially if it's lower quality product, or smoke it in a glass pipe with a bulb on the end, which gives a shorter high, somewhat less physical but with a strong euphoric rush. One of my first dealers was shocked when we got high together and I turned down his pipe so I could crush some of my purchase up and proceeded to snort it.
I know this is going off topic here, but I think the term ''addictive personality'' is not only so nebulous as to be meaningless (effectively begging the question, ''why is X an addict? Because X has an addictive personality''), but a complete cop out that allows one to ignore the socioeconomic, environmental, medical and psychological factors which contribute to addiction.
I've never met a "functioning meth addict" in my life. I have no doubt that they exist, but every time I meet someone who fucks with it, their lives are always wrapped up around that drug, way moreso than other addicts I've been around (cokeheads, opiate addicts, etc). I've done it a fair number of times and it definitely is highly addictive.
The problem with functional addiction is that tends to be a phase between non-addiction and dysfunctional addiction. Most addicts go through it and most of them think they'll stay in it and most of them don't. I think claim can be laid to true functional addiction only when that addiction ends, otherwise, statistically speaking, it's just a buildup to something bigger.
