CBD for Tested Athletes

CBD and Tested Athletes – A Question of Trust

The use of cannabidiol (CBD) in sport has increased dramatically in the last few years, especially CBD creams and gels that can be applied to muscles, joints and tendons. Yet, the vast majority of the products in use contain cannabis plant derived CBD and a large percentage of these products, especially those stated to be ‘broad spectrum’, are highly likely to contain THC in trace or greater amounts. While this may be a tolerable risk for amateur athletes, any exposure to THC over time creates a substantial risk of failing a THC test.
What does ‘broad spectrum’ CBD mean?

In the United States, CBD products can contain as much is 0.3%. Law in the United Kingdom is stricter, with products only permitted to contain less at 0.2% or one milligram per container. In many cases these products are labelled ‘zero THC’ when in fact they are 0.2 or 0.3 percent CBD (or even greater). While this amount is usually too low to induce psychoactive effects (except possibly when ingested), it is not too low to violate WADA (World Anti-Doping Agency) regulations.

Biosportart products contain absolutely no (0.000…%) cannabinoids except CBD. We use only PureForm CBD that is derived from citrus terpenes using organic chemistry

“Cannabidiol (CBD) is not prohibited. However, athletes should be aware that some CBD products extracted from cannabis plants may also contain THC that could result in a positive test for a prohibited cannabinoid.”

WADA: Only pure CBD is permitted

Cannabidiol (CBD) is legal according to WADA (World Anti-Doping Agency) and Global DRO (Global Drug Reference Online). Furthermore, CBD is the only cannabinoid that is legal according to WADA and Global DRO. Biosportart products contain absolutely no (0.000…%) cannabinoids except CBD. Our products do not contain any other cannabinoids, such as THC, CBG, CBN, THCA, etc. PureForm CBD is 99.5% or greater purity, the remainder being limonene, a food-safe citrus terpene.

Why even a small amount of THC or other cannabinoids is a risk.

Consuming or absorbing even tiny amounts of THC can pose a real risk of failing a drug test. This is because THC accumulates in adipose (fat) tissue over time, where it may remain for weeks and even months. A study in the British Journal of Pharmacology (see below) showed that regular exposure to even small amounts of THC can accumulate in fat tissue in significant amounts. And that this THC can effectively ‘reappear’ in the bloodstream after this fat is burned and ‘re-intoxication’ can occur.

THC is stored in fat and when you burn that fat, that THC is released back into the bloodstream. This is why Biosportart’s non-cannabis derived CBD creams and gels are the safest choice for tested athletes.

Re-intoxication is a particular risk for those athletes involved in endurance events that require prolonged periods of exertion or endurance (marathons, triathlons, etc.) or those sports that feature dietary cycles such as ‘bulking and cutting’ such as boxing, MMA, and bodybuilding. The rate of lipid metabolism (fat burning) in these groups can dramatic. The more energy that is expended, the greater risk is of accumulated THC being released — and therefore being detected — directly after competition.

It is possible for athletes that absorbed small amounts of THC over a long period of time to fail THC tests, weeks and even months after ceasing use. This is why Biosportart creams and gels are the safe choice for tested athletes.
