Regarding the commenter that brought this subject up - Great Job.
#! Fact. (formally #1 but above even that) - If your not pissed off, your not paying attention.
If you are new to the subject of Cannabis, this is a good starting point. As a matter of fact most everyone is at this same starting point because, as it turns out, we've all been lied to for a very long time. (Surprise! ;))
Every study, every research grant, anything the public has been exposed to about Cannabis within the past 70 years or so is tainted with a "Reefer Madness". Still palatable today in media coverage from the local rag newsprint to the "lamestream" and off into the internet (even today, Yahoo! censors (among many other things) the word "Cannabis" from their comment forums. This ubiquitous demonization of benefical Cannabis makes experienced consumers intrigued about the legal rational.
As shown in the polls, ballot boxes and uncensored comment sections of any Cannabis related issue, the People Have Spoken - Loudly, I must add.
Continued demonization by major press and politicians shows a disconnect from their customer base. Careful attention to positions best be addressed by these organizations soon before the public begins to demand the funds for the DEA be put into internal investigations of government and major media.
#1 Fact - Cannabis is non-toxic.
There is no scientific LD-50 for Cannabis, There have been no recored medical deaths directly due to cannabis ingestion - Ever.
A discussion here about this basic known medical and scientific fact is rather moot. Suffice to say, prove me wrong.
#1 Myth - Cannabis is a harmless plant.
Keep in mind people, just because it can't kill you doesn't mean it is inert.
Younglings - stay away for now, most recent studies are showing important findings regarding early development of the brain and body.
Absolutely Psychoactive, a person not in the proper mental state could have a "bad" experience. The "painful" self-recognition described in the book Understanding Marijuana partially explains the severe distaste by some users (and politicians).
Although mind opening and wonderful to some people, the substances in this plant have different effects upon different people and most important - children should be educated about the developmental issues of brain and body.
#2 Fact - Cannabis is the most useful plant known to man.
From industry to medicine, the value of Cannabis has long been known.
#2 Myth Cannabis is illegal
The United States never had a Constitutional Amendment declaring Cannabis a prohibited substance as required (only an Act) such as alcohol was. Many states allow for the possession and use of Cannabis for medical reasons and the states of Colorado and Washington have declared Cannabis legal for anyone over the age of 21.
There is some good, some bad - for some ugly look up the incarceration of Daniel Chong
Fact: the number one cause of death related to cannabis is incarceration.
