One motive is that it's cheaper to delete the emission system vs having to replace/repair the unit. Diesels have much more sophisticated emission devices vs gasoline engines, so it's more costly.
One does not roll coal from e.g. an EGR bypass or delete, though! The only way to get thick clouds of black smoke are too much fuel (turn up the pump) or not oxygen (bag over the air filter in the simplest case).
Many states and localities have "visible emissions" rules, where even if your vehicle doesn't have to pass emissions tests, you can still get pulled and cited for actual smoke. I've never been pulled for it (smoke means you're wasting fuel) so I don't know if it's an inconsequential fine or just not enforced generally.
In my lived experience the folks who intentionally want to roll coal are younger guys (something to do in high school) - "matured" diesel owners want little/no smoke for the higher performance
Meth is actually available by prescription in the US for ADHD and obesity [1] (at a much lower dosage than what addicts take)! Opiates obviously are as well.
>is meth, heroin, and cocaine supposed to be safe for you?
Most likely not, but definitely much safer than unregulated "bath salts". And keep in mind, "safe" is not binary, it is a spectrum. Even a lot of common household OTC drugs are not safe if taken in improper dosages or without following the instructions carefully.
And even regarding those drugs that you've mentioned, a giant chunk of the deaths and overdoses occur due to impurities and unknown mixes that are unaccounted for due to the illegal status of those substances.
For example, let's say a heroin addict keeps buying from the same dealer and knows his safe "dosage", which is N grams. The thing is, that's not the real dosage, because street heroin is mixed with tons of garbage fillers to prop up the value and make the drug cheaper to manufacture. So his real "safe" dosage could be 70% of N, with 30% being fillers. Then at some point later, he either switches dealers or his usual dealer switches suppliers, and the fillers only account for 10% of the final product now. So the addict buys his usual "safe dosage" of N grams, without being aware of decreased filler amount(dealers don't post an accurate percentage of fillers in their drugs on the package, cause why bother if it is illegal either way, and it could be that they didn't even know it themselves). Even though the addict thinks he is buying his usual "safe" dosage, in reality his dosage becomes 29% higher (0.9N grams vs. 0.7N grams), hence the overdose.
Note: numbers and percentages are absolutely made up, because i have zero idea about typical heroin dosages and percentage of fillers in those. But my point should still be valid, even with the real life numbers probably being much different.
Absolutely not. Those are very dangerous substances to take. Now add in the additional dangers posed by criminal production. How does a drug user know whether it's really cocaine? Of course, they don't. It's completely unregulated the most extreme manner possible.
Where are you getting that women getting raped or abused is unique to only the porn industry? Is there any hard data, or is this just some bs that people assume happens in porn.
I don't claim that rape is unique to the porn industry; only that porn makes it worse. (Porn can be addictive, so supply increases demand increases supply. This has been documented with respect to CP. As those studies require library access, I will leave it to the reader to find someone with academic library access to read those articles.)
The major studios are a small part of the problem, however, it's the non-U.S. and underground scene that generates most of the problematic content.
