In Memoriam:

Steven McWiliiams

Scared of possible jail time, in constant pain and lired of battling (or medical marijuana patients' rights, Steven McWiliiams committed suicide in San Diego on Monday July 12005 on his 51st birthday.

Mr. McWiliiams was famous nation-wide for his efforts and the legitimacy he lent to the medical marijuana movement. Not taken seriously at first, McWiliiams did nol give up, working for the movement since as early as 1996 when California state voters approved Proposition 215, allowing patients to use marijuana for medical purposes when prescribed by a doctor.

Steven McWiliiams worked to implement Proposition 215 locally in San Diego. Showing up weekly for City Council meetings carrying a marijuana plant, he urged the local politicians to come up with a plan for the distribution of marijuana. As a result the city came up with standards for the number of plants allowed by users. Mr. McWiliiams served on a city-organized committee for a time that dealt with these issues. He ran for city council a few times, when he wasn't alternately suing the city.

In spite of all this, he was convicted in 2003 for illegal cultivation, and sentenced to a six-month federal prison term. Still out on appeal at the time of his suicide, he was in chronic and serious pain, the judge had ordered that he not use marijuana. Mr. McWiliiams suffered severe side


This book is dedicated to Sebastain Orfali; Roger Watanabe; my mother, father, wife and family; all cannabis medical patients; and all the people who have suffered the effects of the War on {prohibited cannabis) Drugs, We share a common affliction. Some law enforcement and political agents have shared our pain; others are in different stages of denial. May the Christian God, Buddah, Alai, Sheeba, and the God you worship, bless you all.

elfects from the use of standard prescription painkillers. He left a note saying that the pain was loo much to bear, and he hoped his suicide would help change the government's position towards marijuana as a medicine.

Memorial services were held in San Diego at City Hall, white roses were passed to the attendees.

Steph Sherer, executive director of Americans for Safe Access said, "Steve McWiliiams was tortured by the federal government because of the medication he needed."

The Native Suns Dispensary opened in San Diego an June 6, 2005, in defiance of the Supreme Court's ruling against individual states' medical marijuana laws. In a 6-3 split-decision, Justice Paul Stevens said that congress has a mural responsibility to change the nation's laws regarding cannabis use for medical patients. In writing the decision, Justice Stevens did find that the federal government did not exceed its authority under law when federal officers raided medical marijuana patients with California state prescriptions.

The War on Drugs

The War on Drugs in "America, Land of the Free" is out of control. This War on American citizens and many other unfortunate souls around the world continues to be driven by fear and misinformation that is spun by numerous US and foreign government agencies.

The War on Drugs concentrates on encarcerat-ing cannabis users and is headed by a drug czar.

Czar is defined by Webster's Dictionary, as 1. A former Russian emporeror. 2. An autocrat, 3. Informal. One in authority: Leader. From these definitioins we know that a Drug Czar is not one to listen to any opposition. Is this the basis of democracy?

The most infamous American Drug Czars include: William Bennet (a tobacco smoker, alcohol drinker and compulsive gambler) General Barry McCaffrey (the most decorated US General and instigator of failed "anticannabis media propaganda"), and John Walters (a career bureaucrat who labels peaceful cannabis consumers as terrorists). All past and present Drug Czars profess "high moral standards."

Many official Government and private reports have recommended legalization or decriminalization of cannabis including:

1928: Le Dain Commission (Canada) recommended to decriminalize or legalize small amounts of marijuana.

1972: the Safer Commission, appointed by President Nixon, reported that laws regarding marijuana should be decriminalized. Nixon rejected that recommendation, and instead endorsed the creation of the US Drug Enforcement Agency (DEA).

1990: California Advisory Panel (appointed by the State of California) recommended that California legalize marijuana, State Attorney General John Van de Kamp refused to publish the report.

2005: The Budgetary Implications of Marijuana Prohibition report is released. The Harvard University report by 500 US economists headed by economist Milton Friedman endorses legalizing and taxing cannabis.

Cannabis has been used medicinally for more than 10,000 years. Cannabis is being legally dispensed medicinally in 10 US slates, Canada, the Netherlands and Spain. Still the US Government classifies cannabis as a Schedule I drug along with heroin as having no medical value.

The July 30, 2004 editon of the Seattle Times reported "Marijuana smuggling case first local use of Patriot Act provision. The US attorney in Seattle, WA charged 15 people in a marijuana smuggling operation. The undercover snitch, a U.S. Immigration and Customs Enforcement agent, posed as a middle man who actually smuggled money from the US to Canada.

The alleged cannabis and money smugglers were charged under the Patriot Act. The Patriot Act was passed into law in the US in order to thwart international terrorism after the September 11 attacks on the World Trade Center towers in New York City. However according to US attorney Todd Greenberg in Seattle, "there is no indication these defendants are connected to terrorism."

Here are a few well documented facts:

Cause of Death Annual Deaths

Tobacco 435,000

Poor Diet and Physical Inactivity 365,000 Alcohol 85,000

Microbial Agents 5,000

Toxic Agents 55,000

Motor Vehicle Crashes 26,347

Adverse Reactions to Prescription Drugs 32,000

Homicide 20,308

With ever increasing prohibition we are growing more cannabis around the world than ever before. Most of the photographs and much of the information was collected outside of the USA. The cannabis laws in the "Land of the Free" are some of the most horrifying and repressive in the world. However, with the artificial "cannabis price support program in a free market" spawned by the US government, the rest of the world is benefiting. Growers from all over the world, including the ones that are willing to risk their freedom and assets in the USA, are able to cash in on this defacto program.

Here is how the program works. Cannabis is illegal. This creates an artificially high price for cannabis because the supply is limited and the demand high. Aggressive entrepreneurs see the opportunity and fill the need in the marketplace. When harsh laws are enforced, entrepreneurs give way to thugs and organized crime who fill the orders for cannabis. Any first year economics student can figure this out!

This information has caught the eye of a few politicians. A growing number of politicians are finding the integrity and moxie required to risk "political suicide" and endorse medical cannabis.

Indoor Marijuana Horticulture


The "Bible" has gone through a complete metamorphosis since the first edition in 1983, The First Edition was just 96 pages, black and white and bound with a pair of staples, i wrote the book on a Kaypro II computer. To typeset I hooked my Kaypro to a VAX mainframe computer, The typeset "galleys" were pasted up into "hard copy," I printed the book on a Multilith press. My wile and I collated pages and stapled them together to form the first Indoor Marijuana Horticulture book. The book immediately became a best seller among indoor growers and has remained on top ever since!

The Second Edition (1985) grew to 288 pages and was christened "The Bible" by indoor growers. The Third Edition (1993) grew to 320 pages and the Fourth Edition (2001) tipped the scales at 132 pages and contained 200 color photos and drawings. The Bible is published in Dutch, German, French, English, and Spanish. There is also a special UK Edition. The Australian Edition was banned by the Australian Government, but lofty Auzzies still find ways to bring in the Bible.

The Bible now has a little larger format (6 x 8.25 inches (150 x 210 cm]), 512 pages and is full color throughout with more than 1100 full color photographs, drawings, charts, and graphs. The Fifth Edition is completely rewrilten to reflect the changes in cannabis cultivation in recent years. Sections on seeds, seedlings, vegetative growth, cloning, flowering, breeding and hash have been amplified substantially, All new sections have been added on greenhouses and outdoor growing. Photos and precise color drawings augment text to simplify information so that it is easier to assimilate.

Digital cameras, fast computers with big hard disks and fast Internet connections have transformed the Bible into a much more complete work.

We were able to hold the price at J521.95 from 1993 until 2005, 12 years. The expense of adding color to each and every page, hiring editors, travel, office overhead, and inflation have made it necessary to sell a minimum of advertising as well as increase tire price to ¡524.95.

The Internet was developed by the DOD (Department of Defense) in the latter half of the 20th century. Government geeks and spooks developed the Work! Wide Web for national security reasons. It is easy to set up a proxy server along with a few other safety precautions to surf with safety so the government cannot track your every move.

Be very careful when surfing the Internet. Check out for more information about surfing safely.

Smart growers, especially from countries with draconian laws, do not e-mail about growing or surf grow sites on a computer located in a grow house. Remember, a person never knows who is peeking at transparent e-mail. "Firewall" software alerts and protects the user against another party tracking a surfing path or lo unauthorized entry into their computer. Ask at your local software store for security software to keep unwanted computer spooks subdued, ched< out the FAQs on [or a complete rundown on Internet security.

Do not frequent marijuana sites or talk shop on the net unless you have taken appropriate security measures.

Internet information can be great or it can be packed with problems. All growers and "authorities" have the same status on the Internet, and can post "facts" to their site or news group. Many times unverified, poorly researched "facts" are either sell-serving or untrue. Always ask yourself if the information you are reading makes sense. If it sounds too good to be true, it probably is. I often surf through many sites and pages before finding something worth retaining. "Free" often means the material is sales oriented. News groups provide an excellent forum to share grow stories.

Marijuana Chemistry

Cannabis is the only plant that produces chemicals called cannabinoids. However, with gene splicing and genetic engineering, it is only a matter of time until cannabinoids are added to other plants. Cannabinoids are ingredients unique to cannabis; the psychoactive cannabinoids are responsible for the mind-bending effects of marijuana. Some cannabinoids get you high. Around 40 cannabinoids have been confirmed to exist, but most are not psychoactive. Here is a short rundown on the six most prominent cannabinoids.

A0 TI-IC, the main ingredient that gets you high, is called: A-'-trans-tetrahydrocannabinol. All cannabis, whether industrial hemp or drug marijuana, contains some A3 THC Industrial hemp cannabis contains infinitesimal amounts while dried flower tops (buds) of potent marijuana can contain up to 25 percent A9 THC. In potent varieties of marijuana, perhaps all of the mind-bending effects are derived from A9 THC. A" THC is found in very low concentrations in cannabis. It also gets you high, but there is so little A" THC in most cannabis that researchers, breeders, and growers concentrate on the more abundant and potent A'1 THC. To simplify matters we will refer to both A'1 THC and AH TI-IC as THC.

Cannabidiol, known as CBD, also appears in virtually all varieties of cannabis. The amount of CBD varies enormously, from a trace to more than 95 percent of all cannabinoids present in a plant. CBD generally has a sedative effect regarding the high you experience. CBD, when combined with THC, tends to postpone the beginning of the high, but the Rood part is that CBD can make it last twice as long. Whether CBD increases or decreases the force of the high is subjective and must be discerned by each smoker.


Cannabinol, or CBN, is produced as THC oxidizes or degrades. Only a trace of CBN exists in fresh bud. Stored and cured tops or hashish have higher levels of CBN, that has converted from THC. Marijuana with high levels of CBN generally makes the toker fee! disoriented, olten sleepy or groggy referred to as a stupefying high. At best, CBN contains only 10 percent of the psychoactive potency of the original THC.

Tetrahydrocannabivarin, called THCV, is the shorter three-carbon propyl that replaces the five-carbon pentyl chain. This compound is associated with the fragrance of the plant. In other words, very pungent smelling marijuana normally contains THCV. Warmer temperatures bring out more smell.
