How do you shoot up a morphine pill?

You don't. Why would you? Pills are made to be eaten, not shot into your veins. You risk your life. Please reconsider if you are thinking of doing this. At the very least, you risk the possibility of a horrible infection in your blood which could kill you. If you got the pill from a doctor, then just eat the thing like he told you. If it belongs to someone else you shouldn't take it at all. Experiments can be deadly. While you may be looking for a quick high, you may just quickly die. Please reconsider. You may not be exempt from the consequences of making a poor choice.
