It's debatable what someone meant or didn't mean, if they don't say it. I tend to go by what someone actually said. Especially on the internet (or writing in general) i.e. people you don't know, whose background you don't know, without intonation etc. There's very little to no information for interpretation.

Now you asked a new question. Fair enough. Unlike the previous question, where Contergan immediately jumped to my mind, for your question nothing jumps to mind. But google helped. I think you wanted to ask a different question, more like what I originally answered to, e.g.:

    Can you name any approved drug that, that when taken over a short course, can over the long term cause the death of the person taking it?

You did ask though:

    Can you name any drug that, when taken over a short course, has had long term detrimental effects to the person taking it?

Yes I can, for example: Heroin. https://en.wikipedia.org/wiki/Heroin

Let's take that apart:

    name any drug

Check. Heroin is a drug. It's even been prescribed as a pain killing opioid.

        The UK Department of Health's Rolleston Committee Report in 1926 established the British approach to diamorphine prescription to users, which was maintained for the next 40 years: dealers were prosecuted, but doctors could prescribe diamorphine to users when withdrawing. In 1964, the Brain Committee recommended that only selected approved doctors working at approved specialized centres be allowed to prescribe diamorphine and cocaine to users. The law was made more restrictive in 1968. Beginning in the 1970s, the emphasis shifted to abstinence and the use of methadone; currently, only a small number of users in the UK are prescribed diamorphine.

    taken over a short term

Check. Heroin is apparently way up there in addictiveness. After a very short period of time, you will be addicted (even if not like some people claim, after the very first use and regardless of dose or your own addiction susceptibility.

    However, contrary to Bayer's advertising as a "non-addictive morphine substitute," heroin would soon have one of the highest rates of addiction among its users.

Also https://web.archive.org/web/20100213101818/http://www.drugre... which curiously notes that nicotine is even more addictive than heroin. I'll not mention nicotine further here though, because the detrimental effect come from the other substances usually taken with it when ingested via tobacco as far as I am aware (tar).

    long term detrimental effects to the person taking it

Check. Detrimental effects of heroin are numerous. And given it's addictive very fast, even side effects that only turn up later, I would definitely include.

    Common side effects include respiratory depression (decreased breathing), dry mouth, drowsiness, impaired mental function, constipation, and addiction.[12] Side effects of use by injection can include abscesses, infected heart valves, blood-borne infections, and pneumonia.[12] After a history of long-term use, opioid withdrawal symptoms can begin within hours of the last use.

Not to mention the constant possibility of overdosing. Meaning death. The ultimate detrimental effect.
