If PMA and DOM are experimental amphetamines, consider that a failed experiment.
Shit sux.
I've never heard anything good about PMA, and what i've heard about all of the DO line compounds was so-so at best (especially for DOM).
No surprise that stuff's almost always sold as something else on the black market.
Which is a crying shame, given that they are much more dangerous than the drugs they are sold as. PMA can also have really nasty interactions with MDMA, which is doubly problematic for an extasy "replacement" with a slow onset ("these pills are probably bunk, gotta get some other rolls, oh wait, why am i in the hospital?").
Evil GMs may mourn the absence of drug interactions in SR rules.
Though being sold woad instead of nitro may make up for that (be sure to buy some skills to identify street drugs if your character is going to use them).
One should, of course, keep in mind that dealers are foremost interested in making a profit- adulterants should be cheaper and/or easier available than the drug they are marketed as (this is why most "my weed was laced with PCP" stories don't hold up to closer scrutiny, you make more money selling it as PCP).
Which limits the number of possible adulterants, especially given the price and availability structure for drugs in SR4.
But yes, to come back to your complaint, most newly developed drugs don't quite catch on. There's a lot of trial and error in developing new psychoactive compounds.
You systematically modify an existing compound, receive dozens of new substances and then go ahead and test them.
Many fail to some degree, some do so horribly.
Once in a while, you come up with a new wonder drug.
Almost all of them make it to the grey market in some way or the other, though, if only for a short amount of time.
@ Brazilian_Shinobi : what KCKitsune said.
Have to file in the next report now.

Getting back to the original topic, i just read up again on the Jazz description in the BBB.
Couldn't find anything to the extend that it has more long-term side effects than cram.
In fact, tempo is the only drug in the game with an exhaustive list of such, but given the duration of a normal campaign, such stuff would usually only come up in an epilogue unless you start with a severe or burnout addiction.
What
can be said about it is that users are more aggressive and hyperactive than cram users.
The deal with Jazz is that it was developed specifically as a combat drug for cops.
From an outgame perspective : giving the GM a tool to boost the opposition against heavily cybered PCs without having to worry about the budget- doubly important back in SR2, when the initiative system was completely broken in favor of wired characters, who spent their additional passes
before anyone else and could shoot 4-8 times before the coppers where able to react.
Faced with such problems, Lone Star turned to chemical augmentation to counter this threat (and you can be sure that a lot of corps, as well as gangs, followed their example).
Now, amphetamine and methamphetamine have both seen use in combat as well (practically all factions in WWII issued one or both compounds to their troops, the USAF hands out dexamphetamine to pilots up to this day), but a soldier is in a totally different situation than a rent-a-cop going up against a wired street sam and needing a short boost.
While cram could be a choice for an extended combat mission, it would leave the officer tweaked out all day long.
Doesn't fit well with the job requirements outside of busting violent offenders.
Customers might take offense to that.
So they needed a compound that allowed the user to return to baseline within an hour or two.
This is where Jazz comes in.
The fluff also indicates that it is much more tailored towards being a combat booster- i'd suspect the high to be more tense, less euphoric and more edgy than cram, though not on the level of Kamikaze (suicidal psycho bloodthirst) or nitro, which is basically a stimulant cocktail and would combine a broad range of effects (user feels all-out WAAAAGH!).
