Long-Lasting Enzyme Chews Up Cocaine 73

MTorrice (2611475) writes "Despite cocaine's undeniable destructiveness, there are no antidotes for overdoses or medications to fight addiction that directly neutralize cocaine's powerful effects. A natural bacterial enzyme, cocaine esterase, could help by chopping up cocaine in the bloodstream. But the enzyme is unstable in the body, losing activity too quickly to be a viable treatment. Now, using computational design, researchers tweaked the enzyme (full paper, PDF) to simultaneously increase stability and catalytic efficiency. Mice injected with the engineered enzyme survive daily lethal doses of cocaine for an average of 94 hours."

      Yes, "daily lethal doses" is really weird. The problem with cocaine is not lethal doses (that's a problem with heroin). It's that the people addicted to cocaine end up completely crazy after a few years. The effect on the brain can be fun, but in the long run it is really destructive.

          My own observations leads me to think that the people with low self-esteem or low self-confidence seem to like cocaine a lot. People without those particular issues don't enjoy it much if at all. I tried it a couple of times and decided it was a real waste of money, but it's really popular in the worlds of arts and politics, two places where people with some real personality issues tend to congregate.

      Nope, but it will save lives from overdoses.

      There's a line of reasoning that's somewhat common, it goes: "We should never do anything altruistic ever, because it will create a moral hazard, and the mere potential of moral hazard is always worse than concrete good." Similar arguments are used against drugs that treat opiate overdoses [wikipedia.org], and relatedly, drugs used to fight alcoholism [wikipedia.org]. Some of this is bound up in the idea that addiction is a moral or character failing, or strictly a psychological disorder that can only be treated with therapy and "getting to the real problem," and anything else we do is simply palliative and forestalls treating the "real" problem.

      To your point, what needs to be done is a real epidemiological study, to see if people really end up taking more drugs, or if the trauma of OD'ing, being revived by the paramedics and spending a week in the ER with heroic interventions isn't sufficient to make some people hit bottom and scare them straight.

      • Oh, I'm not saying that in some contexts it couldn't be a tool, and I'm not saying something which helps prevent someone from dying of an overdose isn't a good thing ... but if some well meaning idiot (and there are many) just decided to give people this 'for their own good', it could have very adverse reactions.

        • More to the point, some people simply aren't happy if someone doesn't suffer, yet don't have the guts to straight-up admit that.

          I think you're still off by one step. They aren't happy with themselves, so they can only feel good if someone else is suffering more than they are. Since they don't feel good about themselves, they cannot be happy no matter what their situation might be, but they can make themselves seem less miserable [to themselves] by contrast, and since your perception of your attitude shapes your attitude, it really does make them feel better.

          These people aren't inherently bad people. They're damaged. Pity the trolls,

      Well, no. This isn't like a speedball where you have two drugs fighting each other - the enzyme removes the cocaine from your system. You're still addicted and the cocaine isn't doing anything, so you take more and it still doesn't do anything. If you take so much that you start to feel it, all that means is that you've exceeded the capacity of the enzyme to break it down and you now are responding as normal. It's still possible to overdose, I'm sure, but presumably more difficult.

      • They'll just pop a hand full of Xanex. There are so many chemicals to alter mood/perception I can't even imagine building enzymes to attack them all.

        Inside six months they will have an online formula for cocaine substitute. Like the heroin addicts figured out valium gives methadone the same stumble as heroin.

  • If they love the powder they will refuse anything that limits the high or the frequency of getting high. I wish i could say that therapy is worth a hoot but so far what I see is cell therapy (the iron bar type) works better than a two thousand dollar a day rehab. Catch them the first time and lock them down until they are forty years old and some can be turned around. Twenty years in a cell can get one past the memories of getting high.

      All qualitative arguments aside, and sticking to purely quantitative evidence: imprisoning drug users has resulted in no reduction in drug users over the last 30+ years. Drug use has risen, unabated by the threat of prison, from the very beginning of our misguided war on drugs.

      Punishing addiction is bad policy. There are far deeper psychological issues surrounding drug addiction that cannot be addressed by the penal code.

        Punishing addiction is an efficient way to reduce crimes. Addicts are often criminals in order to pay for their drug use. Many drugs can enable more violent crimes with both short term and long term effects. Examples: short term effect = feeling numb, indifferent to inflicting pain on others, long term effect = permanent damage of brain functionality.

        Your platitudes aren't supported by facts.

        • by cusco ( 717999 )

          The effect is only temporary, unless you're going to incarcerate them for life or execute all of them. They get out, they commit more crimes unless the cause is addressed first.

    • Yes that's what we should definitely do, lock people up for doing something they like. Lets line up the smokers, alcoholics, gamblers and everyone else with a form of addiction and put them behind bars for 20 years. They'll sure solve societies problems.

      I can't say this politely, you are a fucktard.

      How about we let people do whatever they want as long as they aren't physically hurting anyone else.

Which in turn could further confuse addicts regarding their own tolerance levels and if they obtain coke from a different source, say on a business trip, they'd run the risk of
