There is no real way of telling how many "lines" it would take you to overdose. It would vary based on body mass,size of the lines and quality/concentration of the product since almost all street bought cocaine is "cut" or mixed with something else to increase the amount of product. Usually it is cut with lidocaine or similar to give a numbing sensation but it can also be cut with aspirin, codeine, and sometimes baking soda or even harmful chemicals that can cause severe health problems and even poison you. But to try to answer your question an average person could probably sniff about one gram of pure cocaine rapidly before overdosing. However everyone's body reacts differently so your safest bet is to not use cocaine or any illegal drug as most of the time you don't really know what you're getting and it is extremely dangerous and addictive. Save your money and stay alive, don't use drugs
