Sure. It makes sense, law should be protecting public health - it is a fair assumption. Now, there is a disagreement on the methods, whether making drugs more accessible would have a positive impact on the public health. A common basic argument just going per analogiam with alcohol doesn't have any sense in this context. It's a bit like a child's argument: "other children can binge youtube, why can't I, mommy?". Other arguments, like the lack of quality control in the illegal market, are different - they can't be reversed in such a childish manner and should be taken seriously.

PS Your point of view is very US-centric, I assure you the arguments against drugs in country I live might have been invalid, but definitely not racist.
