One person I feel has gone over the issue well is one by the name of Adam Conover. He made a video involving marijuana, among many other subjects, and always provided sources involving his videos even he often makes them humorous.

Cannabis reverses aging processes in the brain, study suggests
Memory performance decreases with increasing age. Cannabis can reverse these ageing processes in the brain. This was shown in mice by scientists at the University of Bonn with their colleagues at The Hebrew University of Jerusalem (Israel). Old animals were able to regress to the state of two-month-old mice with a prolonged low-dose treatment with a cannabis active ingredient. This opens up new options, for instance, when it comes to treating dementia. Ref. Source 4b.
Remember that the old films that were made were made because a person lost the war on prohibition and needed something else to go after. The fact that they went after Marijuana and made it seem like a life alterating drug when in fact it is not has proven to be a serious unfair war. Now we are learning the truth about marijuana and finding out that it never was dangerous and never should have been illegal.
