The obvious corollary.
Go American. Smoke only American weed, good clean, patriotic, legal reefer. Put the Mexican drug lords out of business once and for all and help our local entrepreneurs and farmers out (Not to mention all the tax revenue it generates). Get high for the balance of payments sake!
In fact, those who are opposed to domestic pot are only helping the illegal growers in other countries. They should be sent to jail.
USA!, USA!, USA!.
And remember -- "A friend with weed is a friend indeed!" -- Freewheelin' Franklin.
