IIt’s illegal because it works. Pharmaceutical companies stand to lose everything.
Health concerns regarding cannabis/marijuana tend to come from a self-fueling group of discredited scientists funded by the pharmaceutical, prison, tobacco, and alcohol industries. They push non-peer-reviewed papers, fraught with conjecture and confounding variables, while relying upon reports issued by others in their own group to further support their own grossly misleading research and clearly biased agendas.
Here’s the real science:
Study: Cannabis/Marijuana Use Not Predictive Of Lower IQ, Poorer Educational Performance
“… to test the relationships between cumulative cannabis use and IQ at the age of 15 and educational performance at the age of 16. After full adjustment, those who had used cannabis more than 50 times did not differ from never-users on either IQ or educational performance. Adjusting for group differences in cigarette smoking dramatically attenuated the associations between cannabis use and both outcomes, and further analyses demonstrated robust associations between cigarette use and educational outcomes, even with cannabis users excluded. These findings suggest that adolescent cannabis use is not associated with IQ or educational performance once adjustment is made for potential confounds, in particular adolescent cigarette use.”

Daily Cannabis/Marijuana Use Is Not Associated with Brain Morphometric Measures in Adolescents or Adults
"No statistically significant differences were found between daily users and nonusers on volume or shape in the regions of interest. Effect sizes suggest that the failure to find differences was not due to a lack of statistical power, but rather was due to the lack of even a modest effect. 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."

The Duke University (New Zealand) Dunedin study, the one which claimed that smoking cannabis/marijuana in your teens leads to a long-term drop in IQ, has been utterly rebuked by a later paper published by the Proceedings of the National Academy of Sciences. They examined the research and found its methodology to be flawed.
"...existing research suggests an alternative confounding model based on time-varying effects of socioeconomic status on IQ. A simulation of the confounding model reproduces the reported associations from the [August 2012 study], suggesting that the causal effects estimated in Meier et al. are likely to be overestimates, and that the true effect could be zero".
