is there drug test in professional chess?

i want to know

Yes.  Someone at FIDE has fantasies of chess someday being included in the Olympics where it's mandatory.  I think at this stage it's pretty random since everyone but FIDE recognizes what a joke it is.

Beta Blockers like propranolol are not allowed

Believe it or not, chess falls under the auspices of WADA and are subject, in theory, to the same drug controls that cyclists are.

I believe testing is performed only at the highest levels of competition, ie. world championships.

The most likely drugs to be abused in our setting would be amphetamines.

I did a quick check at WADA. Beta blockers are a no-no in competition.

If you google WADA, you can pull all that stuff up if you're interested.

i played pretty good on  mdma .

you gotz the AIDz

I am not sure if any drug will help people play chess better other than something for a headache or to relieve pain.
