people might well stick to less harmful drugs like marijuana.

They won't. They'll be right out there in the open destroying themselves--and many more than there are today. And guess who will pay for their numerous attempts at rehab?

If ease of concealment were no longer an issue - as it wouldn't be with legalization - people might well stick to less harmful drugs like marijuana.

They won't. They'll be right out there in the open destroying themselves

The ones who are deep into addiction, perhaps - but even an addict can say to himself, "The better I keep my drugs hidden, the better my chance of getting to use them."

--and many more than there are today.

So you claim.

And guess who will pay for their numerous attempts at rehab?

Any jurisdiction that votes to do so (or votes for representatives who propose to do so).
