Any Marijuana Users?

Data is as data does...

But would you expect Michael Schumacher to start a race after a good sized scooby?

I know nothing about usa cannabis laws, but in the states where it is legal, are you allowed to drive after some dope?

If not why not?

Absolutely not, it comes under the same DUI laws but I am not sure how it is checked. I have a feeling it is more common than I once thought. 

Actually spoken as someone who has ridden my little motorbike under the influence and really experienced the (in my case) realisation of time issues that came with it. Obviously you never have or are in denial. It was pretty scary, and not something to do. I know from the scene of those days that some people would end up in hospital. The drugs are usually mixed with alcohol so it tended to get the blame as easier to process a ban but that was probably not always the case. I remember I used to think of not if but when. Life was hectic at times.

Every study arrives in its own conclusion. The idea is not only to look at what you want to see or listen to what you want to hear. What I learned in reading a research/study is that the first thing you need to look at is not the conclusion but its design. Cross sectional and case control studies are not strong designs because they are highly susceptible to bias.  Also the study was published in 2007. Surely, there are more recent studies than this. If I'm writing a paper about relational effect of Cannabis, I wouldn't be bothered to read a 17 year old journal unless it is a solid randomised controlled trial. Yep, I'm biased

That's your case but that doesn't apply to everyone as everyone is different. 

This thread is just speaking on marijuana, not alcohol which have ruined countless of lives but no one has died from Marijuana and hospitalization happens with due inexperience, not from the drug itself. 

There's no device to prove someone is high on marijuana at a single point in time (unlike alcohol). 

Drivers beware

Which says that it does affect safety...

THC in saliva only lasts a few hours and majority of American police departments don't have saliva tests in their vehicle or a laboratory where it is performed.

no, it isn't a dip stick test.

I found an English link that might be easier to follow. I dont know how the law works in the uk but here in NL a positive saliva test would be followed at the police station by a blood or urine test to accurately measure the THC levels .

Interesting debate.

I am curious about how long the stuff stays in your blood stream, and if, like alcohol, there is a level that is acceptable.

I don't take the stuff very often, and never drive with, but I can do the following day when I feel no effect.

THC is funny. It depends on a lot of factors. THC attaches to your fat cells sooo if you have a LOT of fat, THC will be stored in your system for long HOWEVER it isn't the active-THC (you're not high the next day).

The active THC component, that makes you high, only lasts a few hours in your bloodstream.

BTW there no "acceptable" limit for driving. An officer in the US can pull you over and test and arrest you if you admit to a "I a sip" or even if they have "probable cause". The courts take the word of the officer, 9x out of 10.
