EPFL reveals new suit for healthcare workers

Researchers at Lausanne’s technology institute EPFL have developed a reusable protective suit for medical staff working with infectious diseases such as Ebola in hot climates.

The hermetically sealed suit, developed by EPFL with partners including the University of Geneva and Medicine Sans Frontières, is designed to address problems discovered during the recent Ebola outbreak in West Africa, which killed 11,000 people over two years.

Ill-adapted for tropical countries, the suits worn by health professionals during the outbreak were too hot, expensive and had to be thrown away after one use, EPFL said in a statement.

“When you dress to enter the contaminated zone, you have to put on around 10 different layers,” said Laurent Kaiser, who works at Geneva’s university hospital HUG and is a professor at the University of Geneva medical school.

“You also wear a diving mask that quickly fogs up, surgical gloves and thick aprons. Not to mention that after an hour of sweating in the red zone in your plastic suit your boots are full of water.”

In addition, most protective gear of this type  can only be used once.

“At the treatment centres, hundreds of contaminated suits were destroyed every day, tens of thousands per quarter, despite the cost and all the environmental risks,” Matthieu Gani, project manager for the new suit, said in a statement.

Produced by Sf Tech, a Swiss company that makes drysuits for divers, the new, more comfortable costume can be disinfected in a chlorine solution and reused over a period of three months, said EPFL.

It should also cost four times less than current outfits.

Additional funding is being sought to develop a sturdy ventilation system for the suit, it added.

A prototype is currently on display at the Geneva Health Forum, until April 21st, where visitors can try it on.

The World Health Organization finally declared West Africa free of Ebola in January this year, just over two years after the first case came to light.

More than 500 healthcare workers died during the outbreak.

CANNABIS

UPDATE: What are Switzerland’s rules for cannabis consumption?

Switzerland has a complicated set of rules for both medical and recreational cannabis consumption. Here's what you need to know.

UPDATE: What are Switzerland's rules for cannabis consumption?

Long prohibited and seen as a gateway drug with potentially dangerous impacts, countries across the globe have begun legalising cannabis in recent years. 

While the legalisation for medical use has been widespread, there have also been successful legalisation campaigns in several countries. 

The situation in Switzerland is also in flux and has been complicated by a range of recent changes.

Whether referred to as cannabis, marijuana or hemp, Switzerland’s Narcotics Act qualifies it as “a psychoactive substance”, with tetrahydrocannabinol (THC) being its most intoxicating ingredient.

The law specifies that “only THC is controlled under the Narcotics Act. Other active substances like cannabidiol (CBD) are not subject to the Narcotics Act as they do not have comparable psychoactive effects”.

Here’s what you need to know. 

Switzerland has legalised medical marijuana 

As of August 1st, the use of cannabis for medical purposes will be allowed in Switzerland

Patients who are medically prescribed the drug will no longer need to seek exceptional permission from the health ministry, as was the case prior to August 1st. 

Demand for cannabis-based treatments has risen sharply, with the health ministry issuing 3,000 exceptional authorisations in 2019.

The government “intends to facilitate access to cannabis for medical use for patients” and was therefore lifting the ban on its use for that purpose, it said in a statement.

The previous procedure involved “tedious administrative procedures”, said the ministry. “Sick people must be able to access these medicines without excessive bureaucracy.”

As of August 1st, “the decision as to whether a cannabis medicinal product is to be used therapeutically will be made by the doctor together with the patient” the government wrote

The sale and consumption of cannabis for non-medical purposes will remain prohibited.

The new regulations could benefit thousands of people suffering from severe chronic pain, it added, including those with cancer and multiple sclerosis.

The law change will also mean that the cultivation, processing, manufacture and trade of cannabis for medical use will be subject to the Swissmedic regulatory authority, just as with other narcotics for medical use such as cocaine, methadone and morphine.

Legality of recreational cannabis is determined by the THC

THC of at least 1 percent is generally prohibited in Switzerland and use of products with this (or higher) content may be punishable by a 100-franc fine.

Of course, if someone is determined to smoke it, 100 francs may not be much a deterrent — but that’s a subject for another article.

“By contrast, possession of up to 10g of cannabis for personal use is not considered a criminal offence”, the law states, as long as it is not used by or sold to minors.

And, as with nearly everything else in decentralised Switzerland, “there are still considerable differences between cantons regarding implementation of the fixed penalty procedure”.

However, “cannabis flowers intended for smoking with a high proportion of cannabidiol (CBD) and less than 1 percent THC can be sold and purchased legally”, according to the legislation. 

That’s because, unlike the THC, cannabidiol “does not have a psychoactive effect”.

In other words, low-content THC and CBD will not give the “high” that recreational users seek.

When will Switzerland legalise recreational cannabis?

Currently, small amounts of recreational cannabis are tolerated in Switzerland.

“The decisive factor for classification as a banned drug is how much THC is contained in a cannabis product. If the THC content exceeds one per cent, the product is prohibited. Hashish is prohibited regardless of its THC content.”

As noted by the Swiss government, “If you are caught in possession of a small amount of cannabis (no more than 10 grams) for your own consumption, you will not be fined. In addition, if you supply (but do not sell) up to 10 grams to an adult, e.g. when sharing joints, you will not be fined.”

“If you are caught using cannabis, you may be given a fixed penalty fine of 100 francs.”

In June 2020, the National Council approved a plan to start cannabis trials for recreational use.

The experiments are to be carried out in Switzerland’s larger cities. Basel, Bern, Biel, Geneva and Zurich have all expressed interest in conducting the trials. 

The study seeks to find out how the market for cannabis works – and how to combat the black market. The social effects of legalisation will also be examined. 

At this point, no decisions have been made. However, Swiss authorities have set certain conditions in case recreational use is approved.

The National Council said if cannabis were to be legalised, it must be locally grown in Switzerland – and it must be organic. 

Health Minister Alain Berset noted that legalisation should benefit Swiss farmers even though “very few producers have experience in this area”.

Can you grow your own cannabis?

In truth, a number of people cultivate marijuana plants on their balconies or in their (secluded) gardens for their own personal use.

As it turns out, the law allows it, as long as it is a variety of the plant that does not have a narcotic effect — that is, the THC content must be less than 1 percent. 

By the same token, cannabis-based products with THC content of below 1 percent can be brought into Switzerland from abroad.

However, the import rules differ depending on the type of product  it is — flowers, seeds, extracts, oils, or other goods.

How much cannabis is consumed in Switzerland each year?

Precise numbers are hard to come by, but according to an article in Le Temps, which based its information on a medical study, about 100 tonnes are consumed in the country annually.

Cannabis remains the largest market in terms of volume: it represents 85 percent of drugs consumed in Switzerland, netting between 340, 000 and 500,000 francs per year.
