I can tell you this much:
The advert campaigns on the internet by anti-pot fags are based only on opinions made up by the people making the banners.
Things they say like "One joint is the same as 4 cigarettes." How fucking subjective could you get? I know few people who smoke joints to themselves (believe me...there is no buzz on number 3 if you smoke 2 big fatties early in the day.

Not to mention that they could be talking "light" cigs. But I don't give them the credibility of a study at all - so light or not doesn't really matter
Another great one: "Marijuana takes your energy away." Now - Just because there are Acacia's (its this grotesque little bug that sits on the wall and does its best to wait to smack you in the back of the head when your not looking) on this board - "Someone I know" will be sitting down after 8 hours of filling 53 foot trailers with 100lb boxes all day (Noone else I know can do 4 of them in an 8 hour day with one "helper"

. The problem is that there is NO RELAX MODE. There is a proverbial ROCKET THE ASS OMFG GOGOGO!
There are times when you get stupid on the stuff - but that is the point - like booze - you go to a place you are going to stay or whatever and work it. Things can get confusing if you didn't make your plan ahead of time - but for fuck sakes -I'm a rookie in perl and I can still code like a mofo (get the results I want in any case

. And SITTING ON A FAT LAZY ASS for days will also make the stuff put you to sleep. That is the human - not the drug - being lazy.
So my opinion - plainly spoken is that whoever does these campaigns and spreads phobia HAD BETTER THINK about what they are saying before I shoot those OPINIONS down with FACT.
Not to mention that many many VERY intelligent and well respected people (not rockstars but DOCTORS) use the stuff and don't mind their babies being able to smell the stuff. (Of course you don't let em get enough to goo their lungs
I like that question ;)
BTW. A room full of Jack smells like love. Sometimes the fuckers can get right kibbly compared to other strains, though. And no -I don't ;)
Cheers to all,
