Can't wait for SCOTUS to apply the same logic to drug prohibition, which is also not at all an enumerated federal power (assuming the same logic that alcohol regulation isn't one either).
Oh they won't, because they're activist judges with an agenda not some impartial arbiter of the constitution
Though the one point I will make is that the federal government is enumerated the power to regulate interstate commerce, so while they can't ban the substances, they could make it illegal to transport them over state lines. Such is the reason you still can't take mj from one legal state to the next.
We should still be able to have bodily autonomy and consume whatever substance we want. Just like women should have bodily autonomy and not be forced to carry pregnancies against their will
