Dealers often misrepresent what they sell, cutting with toxic chemicals, lying about purity or even selling an entire different product. With drugs as potent as opiates, it could mean death. In fact, I think this is the leading cause of death by drug use.
These practices should be much more penalized than just selling the drug, even if both are illegal. Just like armed robbery is more severely punished than shoplifting.

There's an important difference there - product safety enforcement vs. morality policing.
Particulary when most dangerous drugs are a result of chemical knockoffs to try and get around supply issues to making reasonably safe ones.
If they make it illegal to sell, then the state must sell it. Otherwise it just doesn't work. Why should people acting legally need to buy from criminals?
Atlanta GA has decriminalized marijuana this year. If caught it's a $60 fee only. Previously it was $1000, up to 6 months in jail, and a criminal record.
This decriminalization should be applied to all drugs. This has been proven to work, everywhere it has been tried.
It depends on whether society values the lives of addicts or just wants to punish them.

It's hard to find truth in any drug related article, but this is the best we have.
As you point out, people often seek certain substances because at some level they feel it will make things better. The improvement they seek may be proportional to the strength of the substance, meaning those seeking out street drugs are probably also in the most dire straits. From that perspective, punishment seems quite cruel--kicking a person when they're already down.
