I guess it's a damn good thing you're a smart person who doesn't smoke weed!
Please cite the part where I claimed to be intelligent. I made no such claim. But I value whatever intelligence I do have. Which is why I give drugs with any evidence, anecdotal or otherwise, of mental decline a very wide berth.
Enjoy your beer, coffee and/or cigarettes, at least the government and their hand-picked research buddies have determined those to be far safer than weed
They have? You have a cite for that? Are you seriously claiming the government has done placebo controlled studies comparing marijuana or THC and alcohol, cigarettes and coffee/caffiene?
Actually I have personally read studies that show caffeine and other stimulants like amphetamines to improve the outcome following brain damage. I have also seen plenty of anecdotal evidence that stimulants in general can increase mental performance. So that much is plausible.
Incidentally I don't drink alcohol or smoke cigarettes and I drink coffee only rarely.
Now that my sarcasm reserves have been fully depleted, can you please tell me how I'm capable of remembering my humongous password, which is ~128 bits of entropy large and ten words long, despite my handicap of having been a daily cannabis user for over 10 years?
If you are referring to a diceware password then 10 words is not particularly impressive. I have a truly awful memory and I also have a ten word diceware password memorized. In any case how good your memory may or may not be at the moment isn't the point. The question is how does it compare to before you started smoking regularly.
How am I even capable of using Linux, which demands a large portion of the brain's memory be dedicated to a plethora of commands, syntax and philosophies?
It demands no such thing. I run Arch Linux and again I have a terrible memory. I just look up commands when (not if) I forget them. Also this does not speak at all to the question of whether smoking marijuana affects memory. All it proves is it doesn't cause actual brain death or mental retardation. But it still could drop your functional IQ by 10 points for every 3 years of 'wake and bake' or something similar. Since peoples' IQs tend to drop every year after their 18th birthdays in any case this would not be simple to demonstrate.
