Years ago I remember reading an article about Tai Chi master Cheng Man Ching. He had been in New York City only a short time (so he arrived right in the middle of the 60's youth movement) and was discussing various topics with his students. He was asked whether or not using marijuana might help develop the flow state in tai chi practice.
He was quick to reply in the negative, pointing out that certain important aspects of mental focus are lost as a result of the mental "high" cannabis induces.
He went on to say that from his viewpoint, regular use would damage the kidneys. Cheng Man Chings knowledgebase was, of course, traditional chinese medicine so he used terms such as jing and essence.
Has anyone heard of western scientific research that corroborates this? I have used google phrase search to look around. Lots of opinions on the pro and against cannabis sites, people trying to sell herbs to counteract ill effects, no scientific research yet.
