Why is marijuana legal?

Answer 1

In the 1930s, Harry J. Anslinger, America's first "drug czar," perpetrated one of the most enormous, most egregious deceptions imaginable, and its results and its lies are still with us today. Many people today believe that marijuana is a dangerous, addictive drug, only because back in 1936, Anslinger began one of the world's greatest public relations campaigns to demonize a plant that is actually less harmful to humans than alcohol or tobacco according to all research. And despite decades of legitimate scientific proof to the contrary, most people still believe the lies Anslinger created seventy years ago.

Answer 2

Medical Marijuana is "legal" only in 23 states of the US and only for medical use (the use of the word legal is tentative as it does contradict the federal law that's in standing currently). As for WHY this was done, and why other states are trying to do this also - is because of the high number of benefits from marijuana when used in this capacity. The very first use though, is to counteract the effects of chemotherapy on cancer patients. Chemo makes most violently ill, and smoking marijuana has proven to reduce these effects drastically. There have also been studies done showing that there may be a link between smoking marijuana and reduced effects of Alzheimer's.

It is also usefull for people suffering from MS or glaucoma
