It’s a hyperbolic title. They’re measuring standardisation metrics for medicinal dosages and future research. It’s a necessary step, since it is very Wild West:

Additionally, doctors prescribe medical marijuana to be ingested in various formats, including joints. But prescribing a dose for smoked cannabis poses a problem Roggen hopes his research can help resolve. “If a doctor tells a patient to take three puffs daily,” he says, “what does that actually mean?”

Robert Strongin, a professor of organic chemistry at Portland State University, who was not involved in the research, agrees that the results illustrate steps toward a way to systematically regulate dosing. “This information could be particularly useful for medical marijuana patients and clinicians for whom dosing control and consistency is a significant issue,” he says. Roggen’s investigation provides a starting point for manufacturers to address issues relevant to quality control and to be able to manipulate the sensory, intoxicating and pharmaceutical effects of the resulting joint.
