True. 6,000 people died of cocaine abuse in 2006. Another statistic said 17,000 died in 2000 from all illicit drugs. Now surely moderate cocaine abuse is causing deaths in people who aren't known addicts.

But tobacco is certainly far far worse at 443,000 annual deaths. Occasional responsible use of hard drugs is likely not that bad for you.

To be fair, the tobacco issue is due to the delivery method of smoking rather than the active ingredient (nicotine). On its own, nicotine is an addictive but relatively mild stimulant in normal doses. People desire it for the typical stimulant effects (energy, focus, wakefulness, appetite suppression) but as long as the predominant delivery method involves the repeated inhalation of carbon monoxide, lung-coating tars, particulates, and hundreds of other hazardous compounds, it comes with a terrible burden to health.

If everyone had been smoking coffee grounds to ingest caffeine all these years, I'd imagine there would be similar issues around caffeine. Thankfully, there are other delivery methods for nicotine which are more in line with those for caffeine but they are often prohibitively expensive (inhalers, gum, etc) or under a lot of pressure from tobacco companies and those who produce the gum, patches, and inhalers (nicotine vaporizers commonly referred to as "e-cigarettes").

I think that as long as people derive a benefit from nicotine (like caffeine) there should be a lot more support for these more novel delivery methods that don't involve the inhalation of burning leaves. You can argue that anything habit-forming is negative and undesirable but as with coffee or tea, people often find it worth the tradeoff of potential blood pressure issues common to stimulants.

I was referring to the fact that neither coffee nor tobacco impairs a person's judgement, or ability to function in society.

For example, Imagine a person who comes to work after smoking a cigarette versus a person who comes after smoking a joint.

Regarding cocaine deaths, that is despite the fact that cocaine is not legally available, and is very expensive whereas cigarettes are readily and cheaply available. Almost all the deaths from cigarette smoking happen to heavy users over the long-term (149,222 of deaths are between ages 50-69 and 250,000 are over the age of 70) when compared to hard drug use. Cocaine is highly addictive, and the fact is a good percentage of the population does not have the self-control to restrict them to "occasional responsible use" (As is amply evident in the case of alcohol)
