BUY LOCALLY, THINK GLOBALLY

I'm writing about Gary Gall's thoughtful letter: "Cannabis is a safe,
effective medicine" (June 10). Suppose that half, or even more than
half, of the people who purchase medical marijuana don't really need
it for medical reasons. That means they are not buying their
marijuana from drug dealers who get their marijuana via Mexican drug
cartels. And it also means they are not buying their marijuana from
drug dealers who also sell other, much more dangerous drugs, such as
meth, heroin, and cocaine. Most marijuana consumers would prefer to
buy locally grown marijuana of known quality, known purity, and known
potency. But if they can't, they buy black market marijuana.
