Kokainstreckmittel steht im Verdacht, Hirnschäden zu verursachen

Wer regelmässig Kokain konsumiert, das mit dem Tierentwurmungsmittel Levamisol gestreckt wurde, zeigt schlechtere kognitive Leistungen und verfügt über eine dünnere Hirnrinde. Dies geht aus zwei aktuellen Studien der Universität Zürich hervor. Die Forschenden schliessen daraus, dass Levamisol neurotoxisch wirken könnte und plädieren für den Ausbau sogenannter Drug-Checking-Programme. (Universität Zürich, 31.10.2018)

Persons addicted to cocaine often find that the drug is much less enjoyable after years of use, yet they have great difficulty quitting. A new brain imaging study shows why this may be so and also why extinction-based therapy may not be effective for cocaine users.

The study, led by researchers at the Icahn School of Medicine at Mount Sinai in New York City, found that in long-term cocaine users, there is global impairment in the ventromedial prefrontal cortex (VMPFC), an area of the brain that is linked to impulse and self-control. (Medscape, 15.09.2017)

Irland. Cocaine – Reduce the Harms

Ireland ranks fourth highest in EU for use of cocaine among young adults

Minister Catherine Byrne launches new awareness campaign

In light of an upward trend in cocaine use and cocaine-associated deaths in Ireland, a new campaign has been developed by the Ana Liffey Drug Project (ALDP) and the HSE to raise awareness about the dangers of using cocaine (powder and crack), and how to reduce the harms associated with snorting, smoking or injecting cocaine. The campaign was launched today, Tuesday 17th July, by Minister Catherine Byrne. (Health Service Executive, Irland, 17.07.2018)

Cocaine-addicted individuals say they find the drug much less enjoyable after years of use, but they have great difficulty quitting. A new brain imaging study led by researchers at the Icahn School of Medicine at Mount Sinai reveals why this might be so, as well as why a common psychological therapy may not work in addicted cocaine users.

Oxytocin protocol appears workable and safe for methadone patients who use cocaine

Some 30 to 60 percent of patients in methadone maintenance therapy (MMT) for opioid use disorders use cocaine. Compared to other MMT patients, those who use cocaine have higher rates of relapse and mortality. Studies with animals have suggested that the hormone oxytocin could be doubly helpful to these patients, by reducing the addictive effects of both opioids and cocaine. Now, researchers supported by the National Institute on Drug Abuse have developed a protocol for adjunctive oxytocin treatment, and a pilot study has indicated that it is workable and safe for MMT patients.

In 2016, 37 percent of overdose deaths involved cocaine and fentanyl without heroin, up from 11 percent in 2015

Last year more than 1,300 New Yorkers died of a drug overdose, and nearly half (44 percent) of those deaths involved fentanyl. (New York City Health Department, 01.06.2017)

Why Females Are More Sensitive to Cocaine

This research:

Examined why females are more sensitive than males to the rewarding and motivational effects of stimulant drugs.

Demonstrated that the female hormone estradiol is responsible for the increased sensitivity.

Identified two signaling pathways—mGluR5 and the cannabinoid CB1R pathways—through which estradiol mediates enhanced escalation of drug administration and greater euphoria in females. (NIDA Notes, 03.08.2017)
