You on drugs? No, smart pills

12 July, 2017Articles, News

Smart Pills abuse has become so widespread that it is no longer a talking point. . But the increasing addiction and abuse of legal drugs among professionals, that is to prescription drugs and over- the-counter medicine and alcohol, is becoming a growing cause for concern.. A survey of 6 000 South African professionals by Professional Provident Society (PPS) recently revealed that 4% of graduate professionals indicated they used substances such as alcohol or medication to cope with stress. Dr Dominique Stott, executive of medical standards and services at PPS, said: “Medication can be regarded as an abused substance when it is used for purposes which it was not intended for or when a patient becomes addicted to the effects.

“Such medication may even be obtained over the counter, such as codeine-containing pain tablets and cough mixtures.

“The side-effects of using this medication, can become addictive and require increasing amounts for the user to get the same effects.

“For example, it can be easy to become addicted to pain medication when one suffers from chronic pain.

“Addicted individuals’ doctor-hop to obtain the medicine they want, as there is no central database to record the dispensing of these medications.

“A doctor might not be aware that their patient also sees other doctors who are providing the same scripts and the patient could be taking vast quantities of tablets”, she said. The South African Community Epidemiology Network on Drug Use showed in 2015 that the abuse of over-the-counter (OTC) and prescription medicine, such as slimming tablets, analgesics, and benzodiazepines such as diazepam and flunitrazipam were erious issues.

Treatment admissions for over-the-counter and prescription medicine, as a primary or secondary drug of abuse, were between 1% (in the northern region of Mpumalanga and Limpopo) and 6% (Eastern Cape). During this reporting period, 225 (2%) of patients across the country reported the non-medical use of codeine, with 87 of the patients coming from Gauteng.

According to Jackie Maimin, acting chief executive of the Independent Community Pharmacy association, codeine use, in particular, often starts out innocently with the use of codeine-based cough syrups or over-the-counter headache tablets.

“Because codeine is less stringently regulated than other opiates, such as morphine and oxycodone, acquiring and abusing it is comparatively easy.

“Though less potent, codeine provides effects similar to morphine.”

“As an opiate, codeine-use has a high risk of its users developing a tolerance and eventually a dependence on it. Although many people begin using codeine to relieve a legitimate condition, regular use frequently leads to abuse as tolerance develops and some codeine users turn to the drug to cope with physical pain and eventually their emotional pain as well,” warns Maimin.

For some, codeine is only part of a larger addiction. Sometimes, it is the gateway drug into addiction to other substances, especially other opiates such as oxycodone or morphine.

ToughLove SA, a self and family help group supporting people out from drug addiction, explained that drug addiction was a complex disorder that was characterised by compulsive drug use. “Every drug produces different physical effects, but the common result is that repeated use can alter the way the brain functions.

Stott also affirmed that dependence on medication such as codeine, oxycodone and benzodiazepines was overtaking illegal drugs in addiction centres.

“It is also established that patients with psychiatric disorders, such as chronic anxiety or depression, can attempt to self-medicate. This becomes a problem in the treatment of the patients as there is not only the psychiatric disorder to treat but also the dependence on an additional substance.”

It was important, she said, that people did not turn to chemical substances as a way of dealing with their challenges and found alternative ways to relieve stress. “Those who feel overwhelmed, even when healthier habits are incorporated into their lives, should seek advice in stress management,” she said.

Cocaine more addictive than first thought, study finds

30 May, 2017Articles, News

People who use cocaine “recreationally” may be closer to becoming addicted than they think, a study has warned.

Even among non-dependent cocaine users, visual cues associated with consumption of the illicit drug lead to dopamine release in an area of the brain responsible for cravings, according to research published in the medical journal Scientific Reports.

Dopamine is a chemical that causes people to seek pleasurable activities, and researchers have known for years that cocaine use triggers the release of the neurotransmitter.

The research suggests that using cocaine just once may cause an addiction.

“The study provides evidence that some of the characteristic brain signals in people who have developed addictions are also present much earlier than most of us would have imagined,” said Prof Marco Leyton, an expert on the neurobiology of drug use and addictions at McGill university in Montreal, Canada.

In people with addictions, visual cues – such as seeing someone using cocaine – are often enough to trigger dopamine release.

This cue-induced release of dopamine shifts to the dorsal striatum, a structure deep inside the brain thought to be particularly important for when people start to lose control of their reward-seeking behaviours.

To better understand how soon this effect might be seen, Leyton’s team used positron emission tomography (Pet) scans to look at what happens in the dorsal striatum of recreational cocaine users.

The scientists created highly personalised cues by filming participants ingesting cocaine in the laboratory with a friend with whom they had used the drug before.

During a later session, subjects underwent a Pet scan while watching the video of their friend taking cocaine.

Exposure to the cocaine-related cues increased both craving and dopamine release in the dorsal striatum.

“An accumulation of these brain triggers might bring people closer to the edge than they had realised,” said Prof Leyton.

The findings also underscored the importance of providing help early to avoid the severe effects of dependency, he said.
