The autopsy showed Foster had a .098 milligrams-per-liter level of THC, or tetrahydrocannabinol, the intoxicating ingredient of marijuana. Pearson said that is a significant level.
“That indicates very recent use,” she said. “I would say she used marijuana within a half-hour or an hour before she died.”

The toxicology report showed that Goodman had THC in his system, but not at a level considered legally impaired. Edibles are a bit more dangerous just because they do have a longer absorption period and a slower drop than smoking," said Breckenridge Police detective Caitlin Kontak.

• The chemistry of medical marijuana is not known and not reproducible.
•  There is a lack of evidence of safety for the use of marijuana under medical supervision.
• There is a lack of evidence of efficacy of medical marijuana.
• Qualified experts do not accept the drug.
• Scientific evidence is not widely available.

 If you have a medical problem, chances are, there are far more effective treatments than smoked marijuana; prescribed treatments have undergone meticulous testing procedures to minimize risk. Though some may be disappointed, today’s smoked marijuana should not be confused with real medicine. Smoking and inhaling a large array of chemicals in order to deliver a drug is a backward step in medicine and a risky step for a patient.

Simply put, marijuana is not a pure compound; there is no way to make sure that ingredients are measured reliably and are consistent from one batch to another. ...

In old-school dope, levels of THC — the psychoactive chemical that makes people high — were typically well below 10 percent. But in Colorado's legal bud, the average THC level is 18.7 percent, and some retail pot contains 30 percent THC or more, according to research released Monday.
"This shows that marijuana is a GMO product just like other products sold by big business. And just like other industries, now you have a big marijuana industry determined to hide these findings from the public. Where is their outcry? Where are the promises to change the way they do business?" 

Because many of these products are packaged to mimic popular candies, they may be attractive to kids, MacCoun said. "There's the concern that young children will find these products and eat them, thinking they are ordinary sweets," MacCoun told Live Science. "This can be a very traumatic experience, and there are even some indications it can be physically dangerous for young children,

For some marijuana users, it is not only the plant itself that may cause an allergic reaction. Pot can become very moldy when it is being stored, and people who are allergic to mold may have reactions,

·        These consequences include impaired short-term memory and decreased concentration, attention span, and problem solving, which clearly interfere with learning. Alterations in motor control, coordination, judgment, reaction time, and tracking ability have also been documented; these may contribute to unintentional deaths and injuries among adolescents (especially those associated with motor vehicles if adolescents drive while intoxicated by marijuana).
·        Negative health effects on lung function associated with smoking marijuana have also been documented, and studies linking marijuana use with higher rates of psychosis in patients with a predisposition to schizophrenia have recently been published, raising concerns about longer-term psychiatric effects. New research has also demonstrated that the adolescent brain, particularly the prefrontal cortex areas controlling judgment and decision-making, is not fully developed until the mid-20s, raising questions about how any substance use may affect the developing brain. Research has shown that the younger an adolescent begins using drugs, including marijuana, the more likely it is that drug dependence or addiction will develop in adulthood.
·         A recent analysis of 4 large epidemiologic trials found that marijuana use during adolescence is associated with reductions in the odds of high school completion and degree attainment and increases in the use of other illicit drugs and suicide attempts in a dose-dependent fashion that suggests that marijuana use is causative.

tudents, parents, teachers and school administrators are finding it increasingly more difficult to protect Colorado youth while at school with nearly 300 different types of edibles on the market.

Medical cannabinoids are here to stay, but intellectual honesty is imperative if we are moving toward exploiting their potential benefits. Owing to rising THC concentrations of products, "medical" marijuana is rarely good medicine. This review has identified the dangers associated with whole­plant marijuana, whether used for recreational or for supposedly medical purposes.

Several problems are associated with marijuana use during pregnancy, because prenatal exposure influences brain development and can result in permanent cognitive impairment. [35] Cognitive deficits resulting from prenatal exposure include inattention; impulsivity; and impairment in learning, memory, and certain aspects of executive functioning. [36] In addition, prenatal exposure to cannabis has been associated with reduction of fetal growth. [37]
For many years, the myth of smoked cannabis being "healthier" or "no worse" than smoked tobacco was perpetuated by pro­marijuana groups. Both smoked cannabis and tobacco contain approximately 4000 chemicals and that these chemicals are essentially identical in both plants.In another recent review, [23] the authors concluded that "smoking of cannabis is not medically recommended due to the potential respiratory tract, dangers of noxious compounds such as polycyclic aromatic hydrocarbons, tar and carbon monoxide."
 
 

Pollster Dan Jones & Associates found that only a third of Idaho residents want to legalize pot, 64 percent oppose and the rest didn’t know.

• 18-24 year-olds oppose pot legalization by 55-47 percent
• 25-34 year-olds oppose it by 61-34 percent
• Idaho Republicans are especially against legalizing marijuana, 80-19 percent.
• 49 percent of Idaho Democrats favor decriminalization of marijuana use, while 48 percent oppose.
• Among political independents, 59 percent oppose legalization, 38 percent favor.

The fact is that there is no level of THC in blood above which everyone is impaired, and below which no one is impaired.  This is not because we need more studies; it’s because of human biology. Consider the following three factors.

Shows that Colorado 12 to 17 age group, 18 to 25, 26+ are significantly higher than US average for past 30 day marijuana use and all showed increased rates between 2011-12 and 2012-13

Changes in Marijuana Use Patterns, Systematic Literature Review, and Possible Marijuana-Related Health Effects

In 2012 and afterwards California 12th graders as compared to their peers in other states became (a) 25% more likely to have used marijuana in the past 30 days, (b) 20% less likely to perceive regular marijuana use as a great health risk, (c) 20% less likely to strongly disapprove of regular marijuana use, and (d) about 60% more likely to expect to be using marijuana five years in the future. Analysis of 10th graders raises the possibility that the findings among 12th graders may reflect a cohort effect that was set into place two years earlier.
