By what mechanism?

Simple.

As you increase the cost of an activity, you reduce the number of
participants.

At a minimun, the number of "Saturday night specials" sold will be
reduced since the cost of ammo for it would more than double the cost
of a usable weapon.

Fine, since you seem to think that one cannot obtain used
wheelweights, would you impose restrictions on the possession of
brand
new wheel weights?

The market all ready pretty much takes care of itself.

Cost of new product negates any cost advantage of trying to reclaim
them for another purpose.

In that case, I suggest that you go have the cops bust every tire
store in the US.

Totally unnecessary.

The industry has been advised of the hazmat procedures.

Don't know of many companies that are willing to expose themselves to
hazmat problems for a nominal sum of money.
