First and foremost, marijuana is an excellent pain killer: without tolerance with proper use and habituation. Also, this anti-emetic, an appetite stimulant, soothing, etc. And side effects like euphoria or the desire to devour are not so bad if your illness negates all the colors of life. Products from cannabis are effective in symptomatic (and not only) treatment of the widest spectrum of various diseases.
I completely agree, I think that's why many countries finally began to recognize this preparation as a good medical product, which has fewer side effects than its closest competitors.
