I do not have access to the specific content of the "Joe and Charlie tapes" or the second "tape" you mentioned.
Regarding the accuracy of content related to alcohol metabolism or any other scientific topics, it's important to note that AA is a mutual aid fellowship and not a medical or scientific organization. While the AA program has helped many people struggling with alcohol addiction, it is primarily based on the principles of spiritual growth, peer support, and the twelve-step recovery process.
If you are seeking accurate information about alcohol metabolism or related scientific topics, it's best to refer to reputable scientific sources, such as peer-reviewed scientific journals, academic institutions, or medical professionals. Alcohol metabolism is a well-studied area of science, and there is plenty of reliable information available from authoritative sources.
