This is not a well controlled study. I’m not opposed to legalization or recreational use, but I have yet to see evidence that corroborates the safety and efficacy to the degree this paper does. I think there are neuropsychiatric effects that can be problematic, and I see that having watched tons of people get hospitalized due to unmasked bipolar disorder and psychosis; depressed patients with insomnia with sleep architecture that is likely worsened by cannabis. Weed should be decriminalized, and it should be regulated imo. We don’t know enough about it.
