Problems and Benefits of Smoking Cannabis

Ok so i have a few problems associated with the herb marijuana. First problem is that it is illegal therefore the drug can be made anyway possible, being mixed with other harmful drugs. But if it was regulated by the gov. they could control the amount of THC that was in it. There are a few medical benefits associated with the herb, and there is extensive research about what happens when smoked. There are also many benefits including economy benefits, and jail congestion would be lessened if the herb was legal.
