As to legalizing meth, coke, heroin? Well....what I would NOT do is continue locking people up for the rest of their lives, or a good percentage of them, for violating the drug laws. And waht I would also do away with is the "war on drugs" and the rest of the "war on...." which our government decides we're in when they are politically popular. They simply don't work, but they DO cost taxpayers and people. I wholeheartedly disagree with the lock them up and forget about them mentality...it's WHY I do what I do for a living.
Yes, I guess I would allow each ADULT to determine what cancer-causing (and sorry, you're gonna need to prove that those cancer causing, if they are, toxins are somehow worse (without the emotional argument) than government sanctioned and promoted cancer causing toxins) toxins they wish to ingest.
Most harmful substances ARE legal, many are government sanctioned. Peiople only get all up in arms about unpopular substances....but it is NOT directly proportional to the harm caused.
To me, it remains lacking in logic and basically futile and prone to a dangerous slippery slope based on the current bandwagon. Period.
