It's amazing the hemp heads ignore what drugs has done to Columbia today. Let's deal with this statement.
It is vague. Misleading. And meaningless.
Drugs have screwed up Columbia because:
(a) they are illegal. Not because they are "drugs". If they were legal, their value would drop sharply. Paramilitary, communist, and terrorist groups could not use them as a source of funding. The US would not spend millions on spraying plant killing chemicals, aircraft maintenance and operational costs, and weapons and training for Columbia's military.
(b) "drugs" mainly means cocaine in the case of Columbia. Not pot.
(c) Gee, ya think if marijuana were legal conditions would change in Columbia? NO - see "a" and "b" above!
Note - the above arguments are not an argument for the total and unregulated legalization of marijuana. They are merely to the specific point that decriminalizing pot for medical purposes will have ZERO impact on the state of affairs in Columbia.
Whoops. And as someone has already pointed out:
Colombia, not Columbia.
