That argument indeed doesn't make much sense to me. If I smoke, its not "this amount regardless of potency or method" rather "to get this high". If I smoked joints which I don't do since I like my lungs it would just mean much more unhealthy hobby. So yes strong stuff is a godsend, can get to desired state more effectively and cheaply too. The only situation where it may make sense is some inexperienced users taking too much, which can easily happen with random illegal street stuff. But its like arguing to ban hard liquors since people can get shitfaced from few shots easier than from beer. And indeed getting properly wasted increases the chance to develop some bad mental issues, father of one of my ex gf ended up with lifelong schizophrenia just from excessive drinking at ripe age of 18. Which is all true but response is - don't do stupid stuff, as it should be with other drugs. Legalizing and having easy available advice / guide is much better.
