THC will blight your training whilst you delude yourself and dream of bullshit.
Perhaps, but that seems a bit presumptuous to me. Living in the Pac NW I've known a lot
of potheads, indeed whole families of potheads, and they're no more deluded than anyone else...so far as I can tell at least.
Read the previous posts concerning the dangers to yourself and others in the dojo when under the influence.
Aikido does not suffer lapses in attention.
It's this last part that makes me inclined to say people shouldn't mix the two. Then again though, sometimes a person will show up to training dog tired and folks don't think twice about it. I remember a study that was done in the U.K. comparing the effects of sleeplessness, marijuana, and alcohol on operating a car. Marijuana was the safest option of the three.
Now, as with driving a car, you're taking a very real risk if you decide to imbibe, and that is not fair to the people around you in my opinion, but I also want to set a little perspective. Compared to the very socially accepted alcohol, marijuana is slight in its effects.
Ok...devil's advocate signing out.
