Re: “Talking to teens about cannabis crucial, parents told at forum

The daily use of Cannabis medicine results in a complete tolerance to the psychoactive effects of Delta 9 THC due to the receding of CB1 receptors in the central nervous system, specifically the brain resulting in no impairment in the ability to operate a motor vehicle while using Cannabis medicine properly.

Cannabis impairment is so vastly different, (and non-consistent) from virtually every other type of drug impairment, including alcohol, that to compare them is actually kind of ridiculous.
The range of impairment goes from Zero to totally impaired. One individual can have 50ng/ml and be perfectly coherent and functional and another can have 5ng/ml and be completely impaired.

The identification and removal from the road, of drivers that are actually impaired by Cannabis use will not be easy but arbitrarily locking up cannabis patients is just going to punish innocent people even more and cost everyone a great deal in court challenges.

I suspect there will also be court challenges on recreational use alone that will not go well for the government simply because the currently proposed laws on cannabis impairment are based on false science and false assumptions.

Adolescent cannabis use and brain systems supporting adult working memory encoding, maintenance, and retrieval

However, cannabis age of onset brain-behavior associations did not differ between groups with a single reported use and those with repeated use, suggesting age of onset effects may reflect substance use risk characteristics rather than a developmentally-timed cannabis exposure effect. Within repeated cannabis users, greater levels of total cannabis use were associated with performance-related increases in dorsolateral prefrontal cortex (DLPFC) activation during maintenance. This pattern of significant results remained unchanged with inclusion of demographic and prenatal measures as covariates. Surprisingly, however, at the group level, cannabis users generally performed better than participants who reported never using cannabis (faster RT, higher accuracy).

Teen Marijuana Use Not Linked to Later Depression, Lung Cancer, Other Health Problems, Research Finds

What we found was a little surprising, said lead researcher Jordan Bechtold, PhD, a psychology research fellow at the University of Pittsburgh Medical Center. There were no differences in any of the mental or physical health outcomes that we measured regardless of the amount or frequency of marijuana used during adolescence.

Daily Marijuana Use Is Not Associated with Brain Morphometric Measures in Adolescents or Adults
Barbara J. Weiland, Rachel E. Thayer, Brendan E. Depue, Amithrupa Sabbineni, Angela D. Bryan and Kent E. Hutchison
Journal of Neuroscience 28 January 2015, 35 (4) 1505-1512;

In sum, the results indicate that, when carefully controlling for alcohol use, gender, age, and other variables, there is no association between marijuana use and standard volumetric or shape measurements of subcortical structures.

Impact of adolescent marijuana use on intelligence: Results from two longitudinal twin studies

vol. 113 no. 5
> Nicholas J. Jackson, E500E508
there was no evidence of a doseresponse relationship between frequency of use and intelligence quotient (IQ) change. Furthermore, marijuana-using twins failed to show significantly greater IQ decline relative to their abstinent siblings. Evidence from these two samples suggests that observed declines in measured IQ may not be a direct result of marijuana exposure but rather attributable to familial factors that underlie both marijuana initiation and low intellectual attainment.
