As has been pointed out already, heroin in itself is not dangerous: it's actually a very useful drug for pain relief. The problem is the pattern of use. This is true of all drugs, and so making artificial distinctions between how "dangerous" drugs are is fraught with difficulty. Heroin is addictive yes. But if you can't go a week without smoking a joint, then you, sir, are addicted, no matter how much you deny it. Not as addicted as a smack-head, but addicted none the less.
As for methadone, it is prescribed, as I understand it (I'm not a pharmacist), because it has such a slow come-down. Essentially the user remains high for much longer than with heroin, and thus is less likely to want to take heroin. In theory. I should also point out that pretty much every death after taking methadone has involved taking at least one other drug, usually alcohol.
And yes, please make sure you understand the difference between:
Methadone
Mephedrone
Methedrone
Methylone.
