Possible misread 
Hi Bill,
After reading the article, I think it is a possible mis-read as far as the intent of the authors. It is unfortunate that the article barely addresses an issue that has been a hot-topic here, but it wasn't written w/ the forum in mind...
That being said, if I may rephrase the three points you mention:
">* The more marijuana is used, the shorter its effects last.<"
=Over time and with regular use, it takes more grass to achieve a high.
">* Tolerance to the psychoactive effects develops with continued use.<" =Smokers don't notice the effects of grass after awhile (see above)
">* Psychological and mild physical dependence gradually<"= Habitual use of pot can lead to mild physical and psycological addiction. 'Mild' meaning there are no 'withdrawal' symptoms.
So, no....the article is not meant in any way to condone the use of pot or alcohol at all.
The article comes across with pretty strong anti-drug and alcohol use statements...but they are mentioned under the particular 'headings' with each type of drug which may be why they appear to say less about pot use.
The important information to all prescription drug users is to read the label, speak openly w/ your doctor about the possible interaction of the drugs in question and diving.
If my understanding is correct, I believe DAN cannot write an article that simply lists drugs and say: "If you take this, you're fine. If you take THAT, you may not dive."
---Again, each individual is unique.
[[And before the grass-smoking contingent jumps my case here, lets all remember the oft-heard phrase, "Yeah, _____ is a 'lightweight'!" ---this in reference to someone who invariably gets incoherent on one hit (one inhalation)....and will be the very first to vehemently deny it.]]
We can make a prediction as to how drugs affect MOST people....but it is no guarantee.
It would be irresponsible to make a 'blanket judgement' and tell the public, 'fine, go ahead....'---or not, when a complete knowledge of an individual's history and a physical exam is necessary. This would need to be done by a professional who knows how to evaluate the information and make an appropriate interpretation of the data.
I hope this helps, Bill.....maybe someone else reading this can shed some more light ???
