I felt amphetamine has entactogen-like effects, before even knowing that they were closely related; imagine what someone knowingly ingesting amphetamine as an entactogen might feel. Why are many entheogens and entactogens illegal if they have many benefits and miniscule possible harm? Well, the short answer is for no reason.
Dislocated shoulder. A dislocated shoulder happens when your upper arm pops out of your shoulder socket. The shoulder is one of the easiest joints to dislocate because the ball joint of your upper arm sits in a very shallow socket. This makes the arm extremely mobile and able to move in many directions, but also means it isn't very stable.
A separated shoulder isn't the same as a dislocated shoulder, but it can be just as painful. If you have a separated shoulder, the ligaments that connect your shoulder blade to your collarbone have become either strained or torn. Your shoulder will feel loose and your arm may feel weak or even numb.
