Driving high is illegal in all US States
Since not many people have been posting facts and only anecdotal evidence, I will start. I will be posting facts that show how marijuana usage can affect driving, or how it can’t. No bias.
Source 1: The US Gov has known that weed impairs driving since 1993 .

Source 2: "...the 3.3% THC dose increased body sway but did not affect brake latency." 2002.

Source 3: "The unadjusted odds ratio for THC was 1.25, representing a significantly elevated risk of crashing by about 1.25 times or 25 percent. These unadjusted odds ratios must be interpreted with caution as they do not account for other factors that may contribute to increased crash risk. Other factors, such as demographic variables, have been shown to have a significant effect on crash risk. For example, male drivers have a higher crash rate than female drivers. Likewise, young drivers have a higher crash rate

than older drivers. To the extent that these demographic variables are correlated with specific types of drug use, they may account for some of the increased crash risk associated with drug use." Page 25-26, paragraph 4, and 1 with respect to page numbers. 2017.

Source 4: "Visual search frequency in these subjects did not change when they were treated with alcohol or marijuana alone. However, when treated with the combination of alcohol and marijuana, the frequency of visual search dropped by 3%. Performance as rated on the Driving Proficiency Scale did not differ between treatments. It was concluded that the effects of low doses of THC (100 μg/kg) and alcohol (BAC < 0.05 g/dl) on higher‐level driving skills as measured in the present study are minimal."
Summary: If you lick alcohol, you won't get drunk. If you smell weed, you won't get high. No shit it won't impair your driving. (For the people who are gonna argue that driving isn't affected.) 2001.

Source 5: "Alcohol significantly increased accelerator, brake, signal, speedometer and total errors but only the speedometer measure showed increased errors under marijuana. This increase suggests that the principal effect of marijuana was to reduce the time that subjects spent monitoring the speedometer." pg 175 paragraph 2
HOWEVER,
"The lack of marijuana effects may have been due in part to the doses being much smaller than were originally thought. Rafaelsen et al. (1973) reported that other workers who examined the same batch of marijuana suggested the subjects received doses of 3 to 8 mg rather than 22 mg THC." 175 paragraph 3
"The higher cannabis doses and the alcohol dose significantly increased brake time and start time. One of the subjects on the 12-mg-THC dose passed 8 out of 10 red lights without activating the brake pedal at all. The 16-mg-THC dose also increased start time. The number of gear changes significantly increased with alcohol and tended to decrease, but not significantly so, with cannabis. Neither drug affected mean speed." 176 paragraph 1
These are all
simulations BTW.
"Both the alcohol and the higher dose of mari- juana were found to result in poorer car handling performance with significantly more cones being hit under these conditions. Under the higher mari- j uana dose, driving speed was reduced compared to placebo. The difference was small but consistent. In the second trial, three hours after treatment, differences among conditions were slight." 197 paragraph 4
THIS IS THE REAL WORLD DRIVING.
And this quote is for all of the people that drive more safe while high.
"In conclusion, marijuana impairs driving behavior. However, this impairment is mitigated in that subjects under marijuana treatment appear to perceive that they are indeed impaired. Where they can compensate, they do, for example by not overtaking, by slowing down and by focusing their attention when they know a response will be required. Such compensation is not possible, however, where events are unexpected or where continuous attention is required. Effects on driving behavior are present up to an hour after smoking but do not continue for extended periods." 187-88 last p and first p.

I challenge every person to find a peer reviewed article about the effects of driving high on marijuana.
