The World Anti-Doping Agency's (WADA) mission is to lead a collaborative worldwide campaign for doping-free sport. WADA works towards a vision of a world where all athletes compete in a doping-free sporting environment.

REVEAL is a platform where you can share information about doping suspicion in a completely anonymous and secure manner – managed independently by the International Testing Agency (ITA). Every piece of information is important in the fight for clean sport and through REVEAL you can support the investigation of anti-doping rule violations or criminal behaviour. Please feel free to contact us at should you have any questions.

The use of Benzodiazepines as tranquilizer in free diving

The serious risks for health - A real doping practice

By DR Michel Lglise

Benzodiazepines are a class of drug substances that impact on the brain and some other areas of the central nervous system to reduce their  excessive  activity  - We can reference  about  50  generics and  100 different brands around the world;

they can be classified in 3  groups  according the time of elimination from the body ( said half life ) :  fast - medium – low elimination

( few hours till several days)  and  according to their most particular effects on the  brain and nervous system

Among but not  limited to : alprazolam ( Xanax ) – chlordiazepoxide ( Librium)- clorazepate ( Tranxene ) – diazepam  ( Valium ) – lorazepam( Ativan)

Oxazepam ( Serax)- Triazolam ( Halcion ) etc etc

All the  BZD  are  classified by the health department of most of the national countries  in specific categories as  risked substances mainly in case of : abuse – misuse of their normal medical  use , possibly huge risks in certain associations  with other medications – association with alcohol …..also grapefruit +  and specific personal  contraindications – but also even in a normal use when  not  respecting the prescription ……

These are  very useful medications but It must be only an use  for  treatment under a medical prescription and never turned from that use as  ex for sport practice  …… that can be an  aggravating factor  of risk  and source of serious accident according to the specificity of each discipline environment and constraints ………

The  normal  use is  limited  to  reduce anxiety chronic or seizures – panic disorder -  induce relaxation and sleep  and  anesthesia for surgery – muscle relaxation-  alcohol withdrawal treatment  -in the frame of  common  daily social life.

The use of BZD is NEVER innocuous  as can make believe  its  large use and overuse worldwide -

A large number of  serious ( even lethal ) accidents are reported when the correct use is not respected

The frequent and common side effects are sleepiness, dizziness, drowsiness, anterograde amnesia  , hangover effects in the next days, adverse effects in cognition and also hypotension, cardiac arrhythmias  , slow heart rate nause, respiratory depression, apnea,  blurred vision

The main recommendation is not to use these products  using or driving machines  and accomplishing  some  dangerous gestures and performances mainly at work and  during the sport practice when needed a total discernment and total mastering of the  situation and full efficiency of the  cardiovascular and respiratory  system.

We  can  be very worried  when BZD  are used to facilitate  the sport practice and performance in or out of competition.

We firstly  think about the  free  diving disciplines ….  the sides effects can induce  a profound and dangerous sedation, reduction or loss of consciousness, heart and respiratory  depression ,even coma , and in all cases  insidious and durable loss of cognition (in severe  accident , a specific antidote in Intravenous must  be  delivered in a huge emergency  on site that is no easy according to the  specific environment in deep  water …)

This a very risky practice, often not always  really felt by the athlete but insidiously dangerous for health , in a short medium or long term

It is also totally unfair as assimilated to  a doping practice to enhance the performance.

There are absolute reasons to use  the benzodiazepines ONLY for  strict , duly evaluated  medical reasons

This is also an occasion to remember that no doping strategy has place in the CMAS  family
