Mar­ket forces

Isis Town and Country - - Opinion -

A RE­CENT study pub­lished in the Jour­nal of Health Eco­nom­ics found that when peo­ple reach the le­gal drink­ing age (21 in the USA), the avail­abil­ity of al­co­hol re­sults in a dra­matic drop in mar­i­juana use. This in­di­cates that mar­i­juana is more easily sourced than al­co­hol by peo­ple un­der the drink­ing age and that al­co­hol be­comes a le­gal sub­sti­tute for illegal mar­i­juana. A re­duc­tion in the le­gal drink­ing age may re­duce the amount of mar­i­juana con­sumed, and con­versely an in­crease in the drink­ing age could in­crease the amount of mar­i­juana use. It shows clearly that mar­ket forces, rather than pro­hi­bi­tion, af­fect drug use. DI­ETER MOECKEL
