It's great to finally see the reefer madness ideology dying down. I can confirm through experience that cannabis is a great pain reliever when extracted into a butter or oil and consumed in food. It is also a great sleep aid. Depending on what you're trying to treat with cannabis its good to know the cannabinoid profile or harvest time of certain strains which can result in different effectiveness. For instance a late harvest is better for a sleep aid then an early harvest, more of the THC has degraded into CBN. Check out my latest strain review(Justin Trudope) for more cannabis knowledge.
