First, it is not the drug but a persons past experiences (usually some kind of trauma) that drives addictive and destructive behaviour. Opiates just happens to be one of the most effective tools to supress and temporarily deal with said trauma.
Secound, methadone is an awful drug primarily prescribed for it's much longer half-life (compared to diamorphine/heroin). This makes it more convenient for the ones who are tasked with controlling the traumatized persons intake of the medication. Diamorphine is less physically addictive than methadone and features considerably fewer side effects.
Alcohol is more damaging to the body and harder and more risky to quit than diamorphine. This fact is easily overlooked because the drug is so ubiquitous and socially accepted in our culture. The recreational and casual use that we observe in everyday life makes us believe that alcohol is a less dangerous drug.
Alcohol and tobacco are among the hardest drugs we have, it's just that we are so habituated to their use that we falsely believe they are safer, less addictive and easier to quit once physically dependent.
Alcohol kills more people than "harder" drugs and is much more acceptable within polite society. Same situation with tobacco, which also happens to be one of the most difficult substances to quit that we know of. Your average patient suffering from substance abuse will have an easier time quitting most drugs in comparison to nicotine. Given intravenously, nicotine is 5-10x more potent in producing a euphoric effect than cocaine.
Heroin, meth, etc. might kill you quicker and be more unpleasant to administer with more noticeable withdrawals, but if we're talking about ultimate cost to society they're not the worst offenders.
