Though the 4th edition of the Hempology 101 textbook has not yet been made available on-line, the 3rd edition has been on-line for years. It is out-dated, as it was written at the turn of the century, but for the most part it is still worth the read. However, when writing the last chapter on the future I did a lot of LSD and did not edit as much as I should have.
If you like what you read please buy the greatly improved 4th edition! Buy the Hempology101 Textbook
