Agreed, throughout my University career I saw far more destruction from booze than I did from weed. If you're a lazy ass riding through school on your parents dime and smoking dope, then the dope isn't your issue. Your issue is you're a lazy ass. Booze is a different animal and what makes it worse is it's a socially acceptable and encouraged behaviour. Alcoholism is a real disease, it's widespread and effects millions, from all social classes and without many of them even knowing it or being able to get help. Yet we spend all this time trying to discourage and rehabilitate pot smokers while alcoholics are left to find help in anonymity. Marijuana has been used medicinally for centuries. It's used in many instances to treat mood disorders such as anxiety and depression. In fact, that might be one of the strongest arguments for widespread legalisation, it would allow for far better control on the amount of the various substances that are present in pot. They can be increased or decreased as required. I've known a number of people, some very close to me, who have used Marijuana to help treat disease and illness, none of them were encouraged to drink however. The only time I've ever heard of alcohol being used medicinally is to cauterize a wound caused in a bar fight.
