In a just published “exit interview” with Rolling Stone Magazine, President Barack Obama opined that marijuana use should be treated as a public-health issue, not a criminal matter, and called the current patchwork of state and federal laws regarding the drug “untenable.”
“Look, I’ve been very clear about my belief that we should try to discourage substance abuse,” Obama said. “And I am not somebody who believes that legalization is a panacea. But I do believe that treating this as a public-health issue, the same way we do with cigarettes or alcohol, is the much smarter way to deal with it.”
He added, “It is untenable over the long term for the Justice Department or the DEA to be enforcing a patchwork of laws, where something that’s legal in one state could get you a 20-year prison sentence in another. So this is a debate that is now ripe, much in the same way that we ended up making progress on same-sex marriage.”
Although the administration, largely in its second term, has permitted states to experiment with marijuana legalization policies without federal interference, it has not pushed strongly for any permanent changes in federal law, such as amending cannabis’ schedule I classification or permitting banks to work closely with state-licensed marijuana businesses. As a result, some marijuana law reform advocates believe that President Obama has not done enough to move the issue forward during his tenure. Responding to this criticism, Obama said: “Look, I am now very much in lame-duck status. And I will have the opportunity as a private citizen to describe where I think we need to go.”
Why Obama believes that he will have greater opportunities to address cannabis policy as a private citizen than he did as President of the United States leaves us scratching our heads, but we certainly hope that he follows through on his pledge to focus on drug policy reform in the next phase of his political career.

Cannabis-influenced driving performance is significantly different from alcohol-induced driving behavior, according to driving simulator data published in the Journal of Applied Toxicology.
Investigators with the National Institute on Drug Abuse and the University of Iowa evaluated simulated driving performance in subjects following their consumption of vaporized cannabis, alcohol, or placebo.
Researchers reported that cannabis administration was associated compensatory driving behavior, such as decreased mean speed and increased mean following distance, whereas alcohol administration was associated with faster driving. Their findings are similar to those of other driving studies, like those here and here.
Investigators also reported that cannabis dosing in combination with low quantities of alcohol “mitigated drivers’ tendency to drive faster with alcohol” – a finding that contrasts with prior data acknowledging that the two substances combined typically possess an additive adverse effect on psychomotor performance.
“THC concentration-dependent associations with decreased speed, increased time below the speed limit and increased following distance suggest possible awareness by drivers of potential impairment and attempts to compensate,” authors concluded. “The compensatory behavior exhibited by cannabis-influenced drivers distinctly contrasts with an alcohol-induced higher risk behavior, evidenced by greater percent speed.”
According to the findings of a recently published literature review of crash culpability studies, “[A]cute cannabis intoxication is related to a statistically significant risk increase of low to moderate magnitude [odds ratio between 1.2 and 1.4].” By contrast, a 2015 case-control study by the US National Highway Traffic Safety Administration reported that driving with legal amounts of booze in one’s system is associated with a nearly four-fold increased crash risk (odds ratio = 3.93).

Researchers from Texas A&M University and the University of Florida, Gainesville evaluated drug use patterns from a nationally representative sample of 2,835 12th graders.
Authors found that youth use of alcohol most often preceded the use of tobacco or marijuana. They also reported subjects’ age of alcohol initiation is the strongest predictor of later polydrug use.
“Alcohol is the most commonly used substance, and the majority of polysubstance using respondents consumed alcohol prior to tobacco or marijuana initiation,” they reported. “Respondents initiating alcohol use in sixth grade reported significantly greater lifetime illicit substance use and more frequent illicit substance use than those initiating alcohol use in ninth grade or later.”
They concluded, “Our results … assert that the earlier one initiates alcohol use, the more likely that they will engage in future illicit substance use.”
The findings are inconsistent with recent claims made by several prominent lawmakers that cannabis is a ‘gateway’ to later substance abuse.
Studies conducted by the RAND Corporation and others have previously dismissed any alleged causal role of marijuana as a gateway to subsequent illicit drug abuse, finding, “There is no conclusive evidence that the drug effects of marijuana are causally linked to the subsequent abuse of other drugs.”

Marijuana consumers do not typically use cannabis and alcohol in combination with one another, regardless of whether they are consuming cannabis for medicinal or social purposes, according to data published online ahead of print in the journal Addiction.
Investigators with the RAND Drug Policy Research Center and the University of California, Irvine surveyed marijuana use patterns among participants between the ages of 18 and 91 in four states: Colorado, New Mexico, Oregon, and Washington. (The use of marijuana for medicinal purposes is legal in New Mexico, while laws in Colorado, Oregon, and Washington permit adults to possess and purchase cannabis for both medicinal and/or recreational purposes.)
Authors reported, ”Individuals who use cannabis do not commonly use it with alcohol, irrespective of whether they are consuming cannabis recreationally or medically.” They concluded, “Fewer than one in five recreational users report simultaneous use of alcohol and cannabis most or all of the time and less than three percent of medicinal users report frequent simultaneous use of alcohol and cannabis.”

Investigators from the University of Victoria in British Columbia assessed the influence of medical marijuana access on other drug-taking behaviors in a cohort of 473 Canadian adults licensed to engage in cannabis therapy.
“Substituting cannabis for one or more of alcohol, illicit drugs or prescription drugs was reported by 87 percent of respondents, with 80.3 percent reporting substitution for prescription drugs, 51.7 percent for alcohol, and 32.6 percent for illicit substances,” they reported.
Rates of substitution were highest among respondents between the ages of 18 and 40. Patients using cannabis for pain were most likely to use pot as a substitute for prescription drugs.
Authors concluded, “The finding that cannabis was substituted for alcohol and illicit substances suggests that the medical use of cannabis may play a harm reduction role in the context of use of these substances, and could have implications for substance use treatment approaches requiring abstinence from cannabis in the process of reducing the use of other substances.”
Evaluations of patients enrolled in state-specific medical marijuana programs, including those in Arizona, California, and Rhode Island, yield similar results — finding that patients are particularly likely substitute cannabis for opioids. According to a recently published National Bureau of Economic Research report, states that permit qualified patients to access medical marijuana via dispensaries possess lower rates of opioid addiction and overdose deaths as compared to states that do not.
