It is time to make it legal. It is in California for medical reasons. It is very benifical to cancer patients to ease the effects of neasua and for glaucoma patients as well.
As for it leading to harder drugs no not any more then someone who drinks can become a alcoholic. I know many people who have smoked it for 30 almost 40 years. Instead of coming home and drinking a beer after work or a glass of wine they light up a smoke. They are Dr's and lawyers and business people of all walks of life living in modern bergs in upscale homes enjoying their nightly joint. It is as normal to my generation (mid-70's) as the martini is to the 60's.
