A recent development (check it out here) might lead the way to a quicker, more easily administered drug test. Instead of the lab analysis of urine, blood, or other fluids, this recent technology might allow first responders, such as EMTs, to assess a person’s exposure to drugs (prescription and otherwise) by simply dipping this device (think pregnancy test) into their saliva.
As of right now, the researchers have been able to demonstrate the success of the technology with cocaine, but it shouldn’t be too long before they can provide similar devices for many different drugs.
Now, it’s true that I usually focus on abused drugs in this blog, but this technology could help medical professionals identify dangerous drug interactions common to many prescribed, properly taken, medications. Given the huge increases in prescription medication abuse in the United States, that could be extremely useful and might save some of the 12,000 lives annually lost to accidental overdoses.
Maybe when these devices get cheap enough they can be used in addiction treatment centers to provide more immediate testing results.
Who knows, one day, the technology might be widespread enough to make home drug-testing a simple reality. Whether that’s a good or bad thing should probably be left to another post…
If I were a betting person (I’m not really), I’d bet that most of you have been to YouTube before. For some of us the video site provides good information and for others it’s an endless source of comedy. Either way, YouTube has also become a hallmark of the youngest generation of computer users – they love to post funny videos of their friends for the whole world to see. Some of those young YouTube users have been posting videos of themselves using Salvia.
Salvia, Salvinorin A, and YouTube
For those unaware, Salvinorin-A (note Salvanorin by the way) is the active, hallucinogenic drug in Salvia, a plant that is legal for those above 18 in the United States. Salvinorin A is a very potent hallucinogen that unlike LSD and many other hallucinogens, does not act on serotonin circuits, but instead acts on opioid receptors to produce short term effects. The range of effects include surfacing of past memories, uncontrollable laughter, sensations with various motor properties and becoming one with an inanimate object.
Salvia’s usage has long been documented among South American Shamans for visions and healing purposes. However, shamans use it only through extraction into tea or through chewing and modern methods of use include smoking or ingestion sublingually. Smoking the drug produces a much faster onset. Chewing Salvia leaves results in a much smaller amount of the drug, allowing the shamans to use the plant therapeutically. Large doses, such as those that are used now aren’t shown to have therapeutic effects.
Interestingly, the opioid receptor Salvia acts on (the Kappa opioid receptor-type) is not the same one that morphine and heroin act on (called the mu opioid receptor). This can leave Salvia users with a dysphoric effect (like depression) that makes for a miserable experience and a desire for the trip to end. Good thing it is a quick trip!! However, Salvia is known to produce different effects in different users, so dysphoria is not always present.
Recently, researchers looked into YouTube videos people posted of themselves or their friends using Salvia. Since Salvia is a fairly short-acting drug, lasting an average of 6 minutes, they were able to see many of the full experiences in their natural environment. Some of the observed effects of salvia included uncontrollable movements, changes in visual perception, laughter and “separateness” of body.
Salvia, addiction, and long term effects
As far as we know right now, Salvia use doesn’t seem to produce many long-term, severe, consequences and it’s addictive properties are not yet known. Still, the experience during use can be quite harsh. The number of hits, as to be expected, closely correlated with the amount of functionality problems exhibiting themselves in diction and fluency of movements. As noted earlier, although usage in low doses may be used for holistic healing purposes, smoking of Salvia does not seem to have any sort of healing powers.
Like many other legal drugs, Salvia use should be undertaken with caution, understanding the potency of the drug, its effects, and the possible consequences. Just because a drug is legal doesn’t mean it’s completely safe – Make sure you know what you’re doing before trying it out.
