Marijuana, Alcohol, Intoxication Self-Ratings, and Driving Performance

Intoxication Self-Ratings: "Both simulator and road studies showed that relative to alcohol use alone, participants who used cannabis alone or in combination with alcohol were more aware of their intoxication. Robbe (1998) found that participants who consumed 100 g/kg of cannabis rated their performance worse and the amount of effort required greater compared to those who consumed alcohol (0.05 BAC). Ramaekers et al.

Driving After Cannabis Consumption

Driving After Cannabis Consumption: "Cannabis is only considered a risk factor for traffic accidents if drivers operate vehicles after consuming the drug. Robbe (1994) found that 30% to 90% of his participants were willing to drive after consuming a typical dose of cannabis. This is consistent with a recent Australian survey in which more than 50% of users drove after consuming cannabis (Lenne, Fry, Dietze, & Rumbold, 2000).

Cannabis Substitution Effects

Cannabis Substitution Effects: "Another paradigm used to assess crash risk is to use cross-sectional surveys of reported nonfatal accidents that can be related to the presence of risk factors, such as alcohol and cannabis consumption. Such a methodology was employed in a provocative dissertation by Laixuthai (1994). This study used data from two large surveys that were nationally representative of high school students in the United States during 1982 and 1989.

Hemp Products and the DEA

"In late 1999, during the development of the 2003 rules (described in the previous section), the DEA acted administratively to demand that the U.S. Customs Service enforce a zero-tolerance standard for the THC content of all forms of imported hemp, and hemp foods in particular.

Potential Economic Benefits of Kentucky Hemp Industry (1998 Dollars)

Potential Economic Benefits of Kentucky Hemp Industry (1998 Dollars): In a July 1998 study issued by the Center for Business and Economic Research at the University of Kentucky, researchers estimated that if Kentucky again became the main source for industrial hemp seed (as it was in the past), the state could create up to 771 new jobs and generate $17.6 million in new earnings.

Federal Antidrug Media Campaign Backfires

"The NSPY [National Survey of Parents and Youth] did not find significant reductions in marijuana use either leading up to or after the Marijuana campaign for youth 12 to 18 years old between 2002 and 2003. Indeed there was evidence for an increase in past month and past year use among the target audience of 14- to 16-year-olds, although it appears that the increase was already in place in the last half of 2002, before the launch of the Marijuana Initiative.

Marijuana, Alcohol, and Driving

Marijuana, Alcohol, and Driving: "When compared to alcohol, cannabis is detected far less often in accident-involved drivers. Drummer et al. (2003) cited several studies and found that alcohol was detected in 12.5% to 79% of drivers involved in accidents. With regard to crash risk, a large study conducted by Borkenstein, Crowther, Shumate, Zeil and Zylman (1964) compared BAC in approximately 6,000 accident-involved drivers and 7,600 nonaccident controls.
