For one: "The research suggests that the development of a legal drug that contains certain properties similar to those in marijuana might help prevent or delay the onset of Alzheimer's disease."
There already is a drug that contains properties similar to marijuana -- it's marijuana. While it may not be legal at the present time, I believe that it is important to, instead of attempting to find a synthetic alternative (which would be far easier to mass produce/sell/market/monopolize) attempt to reconcile the discrepancies within the pro/anti-cannabis legislature to better suit the needs of our current condition.
That said, I was even more disappointed with the article's implication that marijuana is "immoral."
I feel as if these students are forced to adjust to the conditions of their academic system, rather than challenge what they might believe to be fallacious. As a scientific objectivist, this struck me at my core.
