no lie ur …
no lie ur stupid,who ever made this
well, it might have …
well, it might have more tar than a cigarette but it is way more natural thn cigarettes will ever be…we dont put actual tar in marijuana it is a natural substance found in marijuana, and there is nail polish remover and a whole bunch of chemicals….but thats just my opinion…
the gateway theory, …
the gateway theory, a gov survey reports 100 million americans have tried marijuana. how many people did they call? not every one has a phone and some people may not have been at home . If I had to guess I would say they called about 100 million so almost every one. do you think it is likley that an addict has tried marijuana the same way a doctor or lawyer has tried it. can we link these two careers to smoking pot?
the tar in pot does …
the tar in pot does not stick to your lungs like cigs and it is not sprayed with radioactive chemicals like tobacco. fact Most people have increased heart rates from a sexual encounter, jogging, or getting excited. In 2005 one reliable study suggest the marijuana may increase brain cell activity. ofcourse that study didn’t recieve very much attention from the media.
the gateway risk is …
the gateway risk is non-exsistant with weed. ppl who move on to harder drugs have behavior patterns that lead them to take risks. These same ppl are more likely to smoke weed at a young age b/c it is a risk that is preceived as high at the time. later in life, larger risks (harder drugs) are taken do to these behavioral patterns. Coffee has a drug componeant and most hard drug users drank coffee regularly before becoming addicted to hard drugs? Does that make coffeee a gateway drug?
8% of schizoprenia …
8% of schizoprenia cases could be prevented. That is a tiny number considering how many ppl suffer from schizoprenia, so small that it is likely that ther is no statistical signifcance and pot should only be avoided for this reason by those who have schizoprenia risk factors other than pot use.
There are no …
There are no studies it effects your brain and there are no studies it effects your mind. Its just a bunch of people with theory’s. People that smoke cannabis know a lot more about cannabis then People that don’t. You think you can give people this bullshit when we all know the person who made this video never smoked.
IF YOU DON’T KNOW …
IF YOU DON’T KNOW WHY THE GATE WAY THEORY EXISTS THEN YOU SHOULDN’T MAKE THIS VIDEO BECAUSE ITS OBVIOUS!!!!
Ok how do you supose you get canabis when it is illegal. Simple you have to find a dealer. Finding a dealer is a shady buisness. Usually a dealer will have other drugs as well and some day you would be tempted to try some. It is probition that is a gateway not canabis by itself. I’ve smoked weed for years and I have never tried anything like Crack or Meth the dangerous drugs.

The 3rd one is an old article dated 2001, and as always when dealing with psychiatrist, is based on what THEY think is right, thos same people who are drugging our children and l;ove ones, They do not have any impact on my perceptions because I know they are fake doctors and they don’t relate on any scientific evidences in there practice.

Conclusions : …
Conclusions : Cannabis use did not increase the risk of head and neck cancer; however, because of the limited power and duration of use studied, a small or longer-term effect cannot be excluded.
Lets say it’s not a good start for your arguments but it might be the only one, let me check

I took the first source in your list and here is what I found :
Results : There were 75 cases and 319 controls. An increased risk of cancer was found with increasing tobacco use, alcohol consumption, and decreased income but not increasing cannabis use. The highest tertile of cannabis use (>8.3 joint years) was associated with a nonsignificant increased risk of cancer (relative risk = 1.6, 95% confidence interval, 0.5-5.2) after adjustment for confounding variables.

:Teenagers …
:Teenagers typically try marijuana first before trying other drugs”
Teenagers typically try adult Tylenol or eat carrots before trying pot. Should we outlaw carrots and Tylenol?
Many of your points are “could be” or “possibilities” while the rest have for the most part been disproved.
Any legitimate argument you may have presented is far outweighed by personal responsibility, liberty and freedom.
