In announcing his involvement with a group that seeks a "third way" for American drug policy, David Frum explains why he thinks marijuana should be unavailable even to people who can use it responsibly:
The goal of public policy should be to protect (to the extent we can) the vulnerable from making life-wrecking mistakes in the first place.
There's a trade-off, yes, and it takes the form of denying less vulnerable people easy access to a pleasure they believe they can safely use. But they are likely deluding themselves about how well they are managing their drug use. And even if they are not deluded -- if they really are so capable and effective -- then surely they can see that society has already been massively re-engineered for their benefit already. Surely, enough is enough?
