Well, theoretically, I believe a person ought to have the right to do whatever they want so long as it does not harm another individual. This would include digesting and mutilating their own bodies in whatever manner they see fit. A very Libertarian ideal.
The downside is that hard drugs tend to completely alter a person's mind. In fairness, that is the whole point of taking any drug. This is not bad in and of itself. The mind altering part of the drug usually causes addiction. Two problems arise from this.
1) The tend to become worthless once addicted.
2) They physically need the drug and will do anything they have to do to get the drug.
Agree.
With the first problem, you are degrading your society from within. That is never good.
Not necessarily. I assume that your premise is that one degraded person in a society degrades the society. While such a premise is ostensibly sensible, it is much more complex, and many reasonable thinkers do not associate themselves with the thought that society is merely a sum of its parts.
The Libertarian in me, the theoretical/philosophical side of me, says that it is their prerogative. Again, they can do what they want with their life and their bodies. However, the practical side of me, the "realist" side of me, says that society (people within our society) want to mother hen these people. They will not let them fall flat on their face. They will want to support them financially via food stamps, welfare, etc.
True, society might have to support such individuals by providing basic subsistence; however, as a practical issue, this is a relative cost that one must weigh against the cost of enforcing the current legislation. While there are certainly cheaper ways of enforcing the current legislation, there are also cheaper ways of providing basic subsistence.
Oh, and if they have kids, that just really perpetuates the problem. So, to combat this, it seems easier to just outlaw such drugs. And yes, I understand the arguments (failures) against such actions.
I agree that the kids lose when their parents are addicted to narcotics; however, as a practical issue (once again), we must weigh this loss against what kids are losing in a society in which it can be argued that there is a black market which provides more incentive for many of these kids to peddle drugs on the street than to pursue legally permitted employment.
The second problem is the more serious problem. People who are addicted to hard drugs will do anything to keep the high coming. The end result is that it significantly drives up crime against innocent people. The interesting thing about this problem is that it does not apply to all "hard" drugs.
A question arises here with two possible and plausible answers: Why are these individuals turning to crime?
1. They have an altered mind-state. For these crimes, it appears as though it is simply a necessary condition that crime will increase. However, there are ways to control this phenomena. And, if we think about the practice of opium dens, we might be able to identify the key. Certain drugs (marijuana) could be sold and consumed anywhere; certain harder drugs (opium) might be limited to dens where individuals buy, consume, get high, and come down in a controlled environment. They get their fix; they get their high; and, they leave (or, remain forever).
2. Which you seem to embrace below, the high is so overwhelming and tempting, that individuals will do anything to chase it. Many of the harder drugs are too expensive for these individuals to afford; therefore, they will steal to fund their addiction. This theft will often result in physical harm. Regardless of how one tries to deal with and lessen this problem, it might still be a necessary consequence. However, it is worth attempting. Prohibited substances will always be more expensive than they would be were they permitted. Marijuana is an incredibly cheap crop to grow; poppy is cheap; coca is a bit more expensive, but not overwhelmingly so; meth is incredibly cheap to produce. Were these drugs legal, I cannot imagine a situation in which a large manufacturer would not get into the business of mass producing opium and cocaine (like Brown and Williamson mass produces cigarettes); in fact, just like cigarettes, I imagine that the product would be even cheaper because it would be cut with something (tar and other BS). The end result is a cheap low-quality version of these drugs and a more expensive high-end version of these drugs (cigarettes v. Davidoff cigars; Jim Beam v. Johnny Walker Green Label; etc.). The low-quality might be both less agreeable and less potent (just enough to get a decent high). Either way, though, it would be much more affordable to the masses who want to use, resulting in less crime to fund the habit (there would also be less crime attributed to turf war and dealers' justice).
For people that use "high end" drugs (cocaine, etc), this is not a problem; they can afford their drugs and do not engage in various crimes to support their habit. It is the "hard drugs" in the poor communities that gives me concern. They get physically addicted to something they are completely hopeless to support on their own.
Is this more or less confusing than before? I feel like a hypocrite on this subject.
Don't think you are a hypocrite, just have to place faith in the drastic economic consequences, related specifically to the cost of the drugs, that could foreseeably result.
