There is no one to blame for the existence of a thriving underground market for marijuana in LA, , than LA & CA.A gram of concentrated weed for a vape pen + battery is $43.50But then the city and state tax $16.76. Cut that tax in half and people will stop buying from unlicensed shops. And best of all, CA & LA will reap more tax dollars than they are today. No one, not even stoners, like to be gouged by The Man.
