Yes, but why would you want to reduce your chances by using substances that are likely to further reduce your lifespan?
You all go on about how there are not the stats which show illicit drugs to be more harmful than legal drugs. Have you for a moment considered that this might be because a small proportion of the population uses illicit drugs and therefore quite obviously the stats will be skewed accordingly.
If any comparative studies have been done over a lifetime considering the differences in health outcomes betwen those who have used e.g. alcohol and those who have used illegal drugs, I'd be interested for you to offer these.
Plus when someone dies, who is going to front up and say 'well, Mr Coroner, I think it might have something to do with all the heroin, cocaine, et al he has pushed into his veins for dozens of years'?
Are you able to quote controlled, randomised, double blind, longitudinal trials which adequately demonstrate that the long term use of the above drugs do not have a deleterious effect?
Really? I'm sure you will have no problem in providing proof of the above statement.
i.e. a controlled trial showing no more risk in filling your veins with heroin than happening to witness a bar fight.
Quite obviously stuffing your blood supply with the variously horrible substances which the main drug is cut with is going to be potentially lethal, so why in the name of god would you do it???
Is your life so pathetically dull and boring, so lacking in stimulation, that you have to create an artificial euphoria from some synthetic compound?
So what if so called professional people take drugs? Why are you presenting this sad fact as something that you seem to feel legitimises their use?
How do you know what the eventual outcomes have been or will be for these people?
Doctors and dentists, e.g. have no need to access 'illicit' supplies of impure drugs.
They can, and do, very easily access the most pure pharmacological form of whatever they want. All it takes is the dishonesty and lack of ethics to dole out prescriptions for patients who never receive the drugs. Many a drug habit has been so sustained for many, many years. I hardly think your pointing to these people's drug habits as validity for your argument has the slightest drop of merit. They derive their drugs by means every bit as criminal as the pushers.
And further, I can tell you that I've seen the results of this drug use and the eventual outcome is too horrible to describe here.
But, hey, just rock on stuffing your minds and bodies with rubbish. I expect the great Australian medical system will be there for you when you either overdose or experience the inevitable long term results of such abuse.
From the Portugese experence drug decrimialisation has been a success on every social indicater. Probably most importantly Lower over all usage by youth and later take up.

As a tangental aside;
Narrated by Jack Thomson the 1994 ABC documentry "Billion Dollar Crop " can now be viewed on youtube in 5 parts, the VHS cost me $120 back then. Spend an Hour to understand Industrial HEMP...
