I dont do MMA but Ive been training BJJ for 25 years. In my early days I never liked training after vaping. Even now, because I teach usually before I train I need a clear head. But when we do our competition training, so hard stand up to ground training (and I dont teach beforehand), I hit my vape. I have to tell you Im more relaxed and I see things so much clearer. also Im more creative and have more fun. I wish i could do it before every training session.I know some mma guys they take mj 2 days before a important fight to realx and focus.
I did also a lot of martial arts stoned, but no big or important fights just in the training.
I also know a worldclass kendo fighter who was afraid to win cause of thc in the doping test.since thc is in the doping list, pro athlet who wants o win cant take mj...in mma there is no doping test and thats also not good cause of massive amphvitamine and steroid abuse.....
